2.2 Sub-band Channel Assignment SATELLINE-EASy 869

2.2.1 Sub-band

Each sub-band is defined by a start and stop frequency. Furthermore, the maximum allowed power level and maximum duty cycle is defined separately for each sub-band.
2.2.2 Duty cycle

The purpose of the duty cycle limit is to ensure that no single application can occupy this license-free band for more than a certain percentage of time. The term duty cycle defines the percentage of a 1-hour period a single modem is allowed to transmit. The modem limits the duty cycle itself. Duty cycle is limited by the firmware by adapting to the transmitted data. The absolute maximum for a transmission is 1 second after which the transmitter is switched off.

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0
2.2.3 Power level
The power level limit is defined separately for each sub-band. The maximum power limit for each subband is pre-programmed into the SATELLINE-EASy 869 / SATEL Compact-Proof 869. The user can choose from 10, 20, 50, 100, 200 and 500 mW ERP* output power for frequency variant 869.400...870 MHz and for Indian frequency variant 865...867 MHz following power levels: 10, 20, 50, 100, 200, 500 and 1000 mW ERP*. No matter what power level the user has chosen the maximum allowed power level of the chosen sub-band cannot be exceeded. *ERP = The effective radiated power from the antenna relative to a half-wave dipole 2.2.4 Channel assignment
Each sub-band is divided into 25 kHz channels according to a channel assignment scheme defined by the recommendation CEPT/ERC/REC 70-03. The sub-band settings for modems are by default:
· Active sub-band: Subband1 · Subband1: 869.4000 869.6500 MHz, 500 mW, 10 % duty cycle · Subband2: 869.6500 869.7000 MHz, 25 mW, 10 % duty cycle · Subband3: 869.7000 870.0000 MHz, 25 mW, 1 % duty cycle · Subband4: 869.7000 870.0000 MHz, 5 mW, 100 % duty cycle When the user selects the active sub-band, RX/TX frequencies will also switch to Sub-band min. freq. +12.5 kHz (for example 869.4125 MHz for Subband1). Centre frequency of the highest channel within a sub-band: sub-band upper limit 12.5 kHz. Note. The active sub-band can be selected by using SL command SL&B= or selecting on the programming menu. SATEL Configuration Manager (current version 1.12.3) does not support the subband settings yet, neither does LCD. CTS line indicates the duty cycle. Any transmitted data appearing at the serial port outside the duty cycle period is ignored.

5 INTERFACE CONNECTORS & LEDS

5.1 Antenna connector
All models have a single TNC female type antenna connector with impedance of 50 Ohm. The antenna should always be connected when the power is on. Removing the antenna while the transmitter is on may damage the power amplifier inside the transmitter.

5.2 Power supply
SATELLINE-EASy is available in two operating voltage ranges depending on which type of internal power/interface-module has been installed at the factory. The voltage range is marked on the label:
· +7...+27.5 VDC (delivered by default) · +3.5...+7.5 VDC SATEL EASy-Proof is available only in +7...+27.5 VDC operating voltage range. SATELLINE-EASy 869 is available only in +7...+27.5 VDC operating voltage range. SATEL Compact-Proof is available only in +10.6 ... +13.3 VDC operating voltage range.

The radio modem must be connected to a power supply with an adequate current output.

As an increased safety feature, it is recommended to add a fuse between the power supply and the modem. This assures that both, the device and the power supply, is protected against over current situations. Recommended fuse sizes are:

Operating voltage range Current rating of the fuse

+3.5 ... +7.5 V 2.5 A slow

+7 ... +27.5 V 2 A slow

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0

The radio modem is referred to as DCE (Data Communication Equipment) whereas the device connected to it, typically a PLC or a PC, is referred to as DTE (Data Terminal Equipment). The 15-pin female `D'-type connector of the radio modem contains the connections required to establish data communication between the radio modem and DTE.
In order to transfer data, the physical interface between DCE and DTE must be compatible and properly configured. This chapter describes shortly the basics of the physical interface options, the related settings and the operation of the serial interface.
The radio modem contains two separate serial ports Port 1 and Port 2: · Only one port at a time can be selected for communication. · Port1 is configured ON by default. · The physical interface of Port 1 is always RS-232. · The physical interface of Port 2 depends on the selected settings.

The handshaking signals apply to the selected serial port (Port 1 or Port 2). The handshaking signals are CD (Carrier Detect), RTS (Ready To Send), CTS (Clear To Send), DSR (Data Set Ready) and DTR (Data Terminal Ready). The physical level of these signals is always RS-232. The wiring and cable connections are illustrated in chapter INSTALLATION.

SATEL Compact-Proof and SATEL EASy-Proof have only one serial port: RS-232.

6.1 RS-232 interface (Port 1, Port 2)

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0

RS-232 standard defines the method of transferring binary single-ended data serially between DTE and DCE. Although the standard defines the electrical characteristics, timing and meaning of the signals, as well as the pin out of connectors, it is applied in a multitude of slightly differing ways (e.g. different pin configurations). For this reason different computers and peripherals are not necessarily directly compatible with each other. RS-232 standard defines transmission lines, in which each single signal line level is referenced to a common ground level. When connecting equipment using RS-232 interface make sure that the equipment are connected together sharing the same ground potential. Major differences in ground potentials may result to large current flow in the ground (GND) wire and may lead to a malfunction or damage the connected devices! RS-232 has been designed for serial data transfer over short distances (usually less than 15 m). For longer distances, RS-422 or RS-485 is better suited in order to maintain the integrity of data.

6.2 RS-422 interface (Port 2)

RS-422 standard defines a serial data transfer method, which is very similar to the RS-232 standard. In RS-422 however, the signal lines are balanced (or differential) transmission lines. A balanced (or differential) transmission line is formed by using two signal wires together to convey each single signal. Because the state of the signal is defined by the mutual voltage difference (hence the name differential), any common mode disturbances induced into the lines will cancel out. The effect of different signals moving in the same cable will also be smaller than in the case of the RS-232. Transmission distance can be considerably longer than when using RS-232 type of connection, and distances of 1 km are possible.
As an example, let's examine the TX-signal: TX-signal will be transmitted using two lines (A and B). A logical "1" corresponds to a situation, where the voltage on line A is greater than the voltage on line B. Correspondingly a logical "0" corresponds to a situation, where the voltage on line A is smaller than the voltage on line B.

6.3 RS-485 interface (Port 2 externally connected)
RS-485 is an extension of the RS-422 standard and enables the connection of more than two devices on to the same bus. Communication is half-duplex, so there is only one cable pair, compared to two when using the RS-422. The RS-485 standard defines the electrical characteristics of the connections in such a way as to prevent possible data contention states as well as cable shorts etc. from harming the devices themselves.
The modem does not have an internal RS-485 interface. Instead, RS-485 can be established by using the RS-422 interface and wiring the signals externally as depicted below.

6.4 Termination of RS-422/485 lines
Each differential pair of wires is a transmission line. A transmission line must be terminated properly to prevent, or at least minimise, harmful reflections formed between the transmitting and receiving end of the transmission line. A common method of terminating a RS-485 type of transmission line is to connect a so-called termination resistor, between the wires and at both ends of the transmission line. Even when there are more than two devices on the same transmission line, the termination resistors are needed only at the ends of the transmission line. The termination resistor must be selected so that its resistance matches the characteristic impedance of the transmission line as close as possible (typical values range from 100 to 120 Ohm). When using a RS-422 type of connection the termination resistor is connected only at each of the receiving ends. Termination resistors are particularly important when using long transmission lines and/or high data transfer speeds.

User Guide, Version 10.0

6.5 Serial data format

The serial interface uses an asynchronous data format. Any character to be transmitted on the serial line contains a start bit, the data bits (7, 8 or 9 bits), an optional parity bit and one or two stop bits. Data bits are transmitted with the least significant bit first, the most significant bit last. For even parity, the number of 1's in the data plus the parity bit equals an even number. For odd parity, this sum is an odd number.

Start bit

Data bits (lsb first, msb last)

Parity bit Stop bit(s)

Example: The letter C (43 in hexadecimal, 01000011 in binary) is transmitted as shown in the table below when using 8-bit data length:

DATA FORMAT
8 bit, no parity, 1 stop bit 8 bit, even parity, 1 stop bit 8 bit, odd parity, 1 stop bit 8 bit, no parity, 2 stop bits 8 bit, even parity, 2 stop bits 8 bit, odd parity, 2 stop bits

CHARACTER
0110000101 01100001011 01100001001 01100001011 011000010111 011000010011

CHARACTER LENGTH
10 bit 11 bit 11 bit 11 bit 12 bit 12 bit

The overall length of characters (10, 11 or 12 bits) should be taken into account when calculating the data throughput capability of a system. A useful rule of thumb is that the transmission of one character will require roughly one millisecond (1 ms) at 9600 bps.
The serial port settings of the radio modem and the terminal device connected to it must equal otherwise errors will be introduced into the transferred data.

6.6 Handshaking lines
Handshaking signals can be used to control data transfer. For example, the radio modem can inform the DTE that the radio channel is busy, and that it is not allowed to initiate transmission.
A common way of using handshaking signals is to monitor the CTS-line and ignore the others. Usually the terminal device is fast enough to handle the data received by the radio modem, so the use of RTS-line is not necessary.
Handshaking is not needed if the system protocol is designed to prevent collisions (data contention) by the use of polling, or if there is little traffic and also if there is no harm from occasional data contention situations (several radio modems try to transmit at the same time).

6.6.1 CTS line

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0

· CTS (Clear To Send) is a signal from the radio modem to the DTE. It indicates when the radio modem is ready to accept more data from the DTE. The options for CTS line are:
· Clear To Send - CTS line is set active when the radio modem is ready to accept data for transmission. CTS will shift into inactive state during data reception, and at the end of transmission. CTS shifts back into active state either when reception ends or the radio modem has finished data transmission.
· TX buffer state - CTS will shift into inactive state only if the radio modem's TX buffer is about to overflow. This typically happens when the transfer speed on the serial interface is greater than on the radio interface, and the size of transmitted messages is large.

6.6.2 CD line
CD (Carrier Detect) is a signal from the radio modem to the DTE. It indicates when there is activity on the radio channel. The options for CD line are:
· RSSI-threshold - CD is active whenever a signal exceeding the level required for reception exists on the radio channel. It doesn't make any difference if the signal is an actual data transmission, a signal of a radio transmitter not belonging to the system, or even an interference signal. CD is also active when the radio modem itself is transmitting.
· Data on channel - CD will switch to active state only after recognition of a valid data transmission. CD will not react to interference signals or noise.
· Always ON - CD is always in the active state. This option can be used with terminal equipment that treats CD line as an indicator of an active connection.
· Ext Antenna Control CD follows the status of the transmitter. This option can be used for controlling external equipment e.g. antenna switches.

6.6.3 RTS line
The options for RTS-line are:
· Ignored - RTS-line status is ignored.
· Flow control - The radio modem transmits data to the terminal device only when the RTS-line is active. Non-active state of the RTS-line will force the radio modem to buffer the received data. This option is used if the terminal device is too slow to handle data received from the radio modem.

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0 · Reception control - RTS-line controls the reception process of the radio modem. An active RTS-
line enables reception (as normal). Non-active RTS-line will interrupt reception process immediately, even if the radio modem is receiving a data packet.
6.6.4 DTR line
DTR (Data Terminal Ready) has a special function in the radio modem - it can be used as an external ON/OFF switch for power saving purposes.
The radio modem is: · ON, if the voltage at the DTR pin is more than +3 VDC · OFF, in the Standby Mode if the voltage at the DTR pin is less than +0.6 VDC
NOTE: If the DTR pin is not connected, the radio modem is ON.
6.6.5 DSR line
DSR (Data Set Ready) is a signal from the radio modem to the DTE. It indicates that the radio modem is powered up. DSR is typically ignored.
6.7 Pause length
The modem recognises a pause on the serial line (a pause is defined as a time with no status changes on the RS-232 interface TD-line). The pause detection is used as criteria for: End of radio transmission - When the transmit buffer is empty and a pause is detected, the modem stops the transmission and will then change the radio to the receive mode. SL command recognition - For a SL command to be valid, a pause must be detected before the actual command character string. User address recognition - In order for the start character to be detected, a pause must precede it in transmission.
Traditionally, in asynchronous data communication, pauses have been used to separate serial messages from each other. However, the use of non-real-time operating systems (frequently used on PC-type hardware) often adds random pauses, which may result in the user data splitting into two or more separate radio transmissions. This may cause problems especially in the systems including repeater stations.
In order to match the operation of the radio modem to the user data, the Pause length parameter can be adjusted on the programming menu. It may have any value between 3 and 255 characters. The default value is 3 characters.
Notes: The absolute time of Pause length is depending on the serial port settings. For example, 1 character is ~1.04 ms at 9600 bps / 8N1 (10 bits).
30

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0 The maximum absolute time is always 170 ms independent from the value of the Pause length given in the set-up. An increase in the Pause length increases the round trip delay of the radio link correspondingly; this is due to the fact that the radio channel is occupied for the time of the Pause length after each transmission (the time it takes to detect a pause). If this is not acceptable, the TX delay setting may also be useful in special cases.
6.8 Data buffering
Whenever the radio modem is in Data Transfer Mode it monitors both the radio channel and the serial interface. When the terminal device starts data transmission the radio modem switches to transmission mode. At the beginning of each transmission a synchronisation signal is transmitted and this signal is detected by another radio modem, which then switches into receive mode. During the transmission of the synchronisation signal the radio modem buffers data into its memory. Transmission ends when a pause is detected in the data sent by the terminal device, and after all buffered data has been transmitted. When the serial interface speed is the same or slower than the speed of the radio interface, the internal transmit buffer memory cannot overflow. However, when the serial interface speed exceeds the speed of the radio interface, data will eventually fill transmit buffer memory. In this instance, it will take a moment after the terminal device has stopped transmission of data for the radio modem to empty the buffer and before the transmitter switches off. The maximum size of transmit buffer memory is one kilobyte (1 kB). If the terminal device does not follow the status of the CTS-line and transmits too much data to the radio modem, the buffer will be emptied and the transmission is restarted. In the receive mode, the buffer works principally in the above described way thus evening out differences in data transfer speeds. If the terminal device transmits data to a radio modem in receive mode, the data will go into transmit buffer memory. Transmission will start immediately when the radio channel is available.

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0

All modem types have a single TNC female type antenna connector with impedance of 50 Ohm.
SATELLINE-EASy, SATEL Compact-Proof and EASy-Proof (330 420 / 403 473 MHz) offers the radio settings for user to select:
· Channel spacing: 25 kHz, 20 kHz or 12.5 kHz · Frequency can be any 6250 Hz divisible frequency between 330 420 *) / 403...473 MHz in case
the Channel Spacing is 25 kHz or 12.5 kHz (for example 403.000 MHz, 403.006250 MHz, 403.012500 MHz) · Frequency can be any 10000 Hz divisible frequency between 330 420 *) / 403...473 MHz in case the Channel Spacing is 20 kHz (for example 403.000 MHz, 403.010 MHz, 403.020 MHz)
*) 330.000 389.950 MHz, 390.050 420.000 MHz
SATELLINE-EASy 869 and SATEL Compact-Proof (869 MHz freq.range) has a fixed 25 kHz channel spacing. See chapter 2.2 Sub-band Channel Assignment SATELLINE-EASy 869 for further details regarding usage limitations.
The data speed of the radio interface depends on the radio channel spacing: · 25 kHz channel => 19200 bps · 12.5/20 kHz channel => 9600 bps
The data speed over-the-air is irrespective of the data speed of the serial interface. If the two differ from each other, the radio modem will buffer the data (max 1 kB) temporarily.
Please note that any communication link introduces an extra time delay called latency that affects the system performance. It is the minimum time experienced by the data between the moment when the data appears at the serial interface of the transmitting modem and the receiving modem. Appendix B presents measured transfer delays in details.

7.1 Transmitter

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0

The output power of the transmitter is adjustable (see the table below for available values). The greatest allowable power depends on limits set by local authorities, which should not be exceeded under any circumstances. The output power of the transmitter should be set to the smallest possible level such that it still ensures error free connection under variable conditions. Excessively high output power levels used in short link spans can cause interferences and affect to the overall operation of the system.

The antenna (or a 50 Ohm attenuator) should be always connected to the antenna connector while the transmitter is being used in order to guarantee the maximum lifetime of the transmitter.

NOTE! Setting the transmitter output power to such a level that exceeds the regulations set forth by local authorities is strictly forbidden. The setting and/or using of non-approved power levels may lead to prosecution. SATEL and its distributors are not responsible for any illegal use of its radio equipment, and are not responsible in any way of any claims or penalties arising from the operation of its radio equipment in ways contradictory to local regulations and/or requirements and/or laws.

7.2 Receiver

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0

The sensitivity of the receiver depends on the channel spacing of the radio modem (=data speed of the radio interface) and on the mode of the FEC (error correction).

Receiver sensitivity Frequency range
403 473 MHz
869.400 870 MHz 865 867 MHz

FEC ON -111 dBm -114 dBm -114 dBm -111 dBm
-111 dBm

The radio modem measures the received signal strength (RSSI) of the receiver constantly. The Signal Threshold setting determines the received signal level above which the search for the radio messages is active. It is recommended that values given in the table above are used as a basis. If the threshold is set too low (the CD LED is ON constantly), it is possible that the receiver is trying to synchronise itself with noise. In such a case the actual data transmission might remain unnoticed. If the threshold is set too high, the weak data transmissions will be rejected although they could be otherwise receivable. Signal threshold should only be changed for a reason - for example in the following cases: Continuous interference is present and the desired signal is strong. In this case the signal threshold can be increased to prevent the modem from synchronising to the interfering signal(s) and /or possible noise. Maximum sensitivity should be achieved and the desired signal is very weak. In this case the sensitivity could increase by decreasing Signal threshold. This type of situation is usually a sign of a poorly constructed radio network / contact. Bit errors and momentary loss of signals can be expected in this kind of a situation. Some data might be successfully transferred.
The radio modems equipped with an LCD display show the RSSI of the last received message in dBm units. The RSSI can be requested also locally by using a special SL command (SL@R?). The RSSI value is available 7s after the receiving the message. After that the value is returned to zero.
7.3 Encryption

Data security is often a concern when using radio communication. In the SATELLINE-EASy product family an AES128-bit encryption (CTR-mode) on the air-interface ensures privacy in the radio network. The principle of encryption in the radio path is to collect a certain amount of data to a shift register and manipulate it according to a certain rule. Every data packet is encrypted individually. The process of encryption adds 10 ms delay in the data flow to each sent data packet (<5 characters) and must be avoided in the cases where low latency is the most important requirement.
AES is open source software from public domain. Author: Brian Gladman (U.K). The CTR-mode is SATEL's in-house implementation.
Separate product models from the SATELLINE radio modem family supports the encryption for the RF interface. The models supporting this feature and encryption level can be viewed in SATEL WEB sites at www.satel.com/products/. The radio models that does not support the encryption feature are compatible with the radio models with the encryption when the feature is disabled. It is not possible to
34

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0 update/change the models NOT supporting the encryption to support this feature in the field. This task can be executed is SATEL factory premises and will be charged according to the service price list. The factory default value for the encryption feature is OFF state. The setting state with the static, distributed encryption keys have to be set equally to the radios in the same radio network.
Please contact SATEL for more detailed information regarding the radio network compatibility settings in radio network between different models (channel width, radio frequency etc.).
The encryption password key is generated by using Main and Aux keys + in the beginning of the data packet transferred changing 32-bit string. It is mandatory to insert both information keys with the mentioned length keys. Options for generating the encryption keys are:
· Manually via terminal connection: · SL commands · Programming mode · Automatically with password via Configuration Manager software (generates automatically the
Main and Aux keys)
It is recommended to set up a radio network with encryption enabled by using only one selected configuration way. The equivalency of the encryption keys between radio modems can be verified from the Key Hash information field. Last 4 marks indicates the equivalency [0-9, A-F].
NOTES: The encryption works ONLY in SATELLINE-3AS radio compatibility mode LCD UI does not include any of the encryption information or settings It is not recommended to use the encryption with Source Routing with <10B message sizes Restoring the factory settings doesn't effect to the Encryption -settings
7.4 Radio state
This setting allows users to disable/enable the transmitter. Unless overridden by the factory configuration, users can select state of the radio by using Configuration Manager software (starting from version 1.8.0) and selecting the value of Misc settings Enabled Radio States: Tx/Rx (both transmitter and receiver are enabled) Rx Only (transmitter disabled, receiver enabled)
In case the factory configuration defines the modem as Rx-only device, the value can't be changed by the users.
Programming menu / LCD Sub-menu Radio setting Radio state provides "TX/RX" or "RX Only" selections

7.5 Priority RX/TX

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0

Priority setting selects the priority between reception and transmission. The setting can be changed in Programming Mode. By default, transmission has higher priority than reception i.e. the default value is Priority TX.
Priority TX means that a terminal device attached to a radio modem decides the timing of the transmission. The transmitter is immediately switched on when the terminal device starts to output data. Should reception be in progress, the radio modem will stop it and change to a transmit state. There is no need to use any handshaking for the control of timing.
Priority RX means, that a radio modem tries to receive all data currently in the air. If a terminal device outputs data to be transmitted (or an SL command) it will be buffered. The radio modem will wait until the reception has stopped before transmitting the buffered data. This will result in timing slacks to the system, but decreases the number of collisions on the air; this is particularly useful in systems based on multiple random accesses.

7.6 Forward Error Correction (FEC)
FEC improves the reliability of data transfer over the radio by adding additional correction information to the radio messages. Based on that information, the receiving radio modem will be able to correct erroneous bits provided the ratio of erroneous and correct bits is reasonable. However, the use of FEC decreases the data throughput, because the amount of transmitted data increases about 30 % (see Appendix B). FEC should be used on long distance links and/or if the radio channel is "noisy" in other words suffering from interfering signals.
NOTE! All radio modems, which are to communicate with each other, must have the same setting for FEC (ON or OFF). If the transmitting radio modem and the receiving radio modem has different settings, data will not be received.

7.7 Error checking
When the error checking is switched on, the radio modem will add a checksum to the transmitted data. When the data is received, the checksum is verified before data is forwarded to the serial port. Options for error checking can be accessed in the Additional setup menu in the Programming Mode
OFF (default setting). Received data is not verified at all. In practice, this is the fastest way to operate, because the data is given out from serial port immediately after it has been received. This is recommended method, if the application protocol already includes error checking functions.
Error check verifies the data in small blocks and they are delivered to DTE as sub messages after validating. Once an error is detected, the rest of the message is ignored. In practice, if the error appears in the middle of the message, the first part is forwarded to DTE and the data in erroneous sub-message and after that will be lost.
36

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0 Full CRC16 check adds two checksum characters at the end of the user data message. At the reception end the receiver receives first the whole package and if the checksum matches the data message is forwarded to the serial port. If Full CRC16 check is selected it must be set ON for all radio modems in the same network. Otherwise the checksum characters appear at the end of user message on the serial port.
7.8 TX delay
The radio modem can be configured to delay the beginning of a radio transmission by 1...65000 ms. The function can be used to prevent packet contention in a system, where all substations would otherwise answer a poll of a base-station simultaneously. During this delay data sent to the radio modem is buffered. Even when the priority setting is "RX", the radio modem is prevented to change over to the receiving mode during the period of the TX delay. If TX delay is not needed, its value should be set to 0 ms.
7.9 Add RSSi to data
RSSI info "\02RSSI:-nnn dBm\03" will be concatenated to the end of serial port messages, nnn is three digit decimal number.
7.10 Separate RX/TX-frequencies
Modem can transmit (TX-frequency) and receive (RX-frequency) on separate frequencies. The switch between the frequencies introduces an extra 40 ms delay in the data transfer that must be taken account when designing the system.
7.11 Free Channel Scan (FCS)
NOTE! Free Channel Scan (FCS) is not applicable to modems using 869.400 870 / 865 867 MHz frequency range. Free Channel Scan (FCS) is designed for one-way transmission between one transmitter and one or more receivers when there are at least two different radio frequencies available. The transmitter monitors the noise level of the channels between the transmissions and finds the best transmission channel. The receivers scan and follow the frequency of that particular transmitter consequently. A more detailed description of FCS function and FCS terminal software is available from the manufacturer or from the nearest distributor.

7.12 User data whitening

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0

In some cases, if the user data includes a large number of constant characters, additional bit errors may appear. The use of error correction (FEC) is recommended in such cases. If that is not possible, the Data whitening feature can be used to improve the reliability of data transfer. The feature is set on/off in the programming mode.

NOTE! All radio modems, which are to communicate with each other, must have the same setting for Data whitening (ON or OFF). If the transmitting radio modem and the receiving radio modem has different settings, data will not be received correctly.

7.13 Pacific Crest and TRIMTALK compatibility

NOTE1 Pacific Crest and TRIMTALK compatibility is not applicable to modems using 869.400 870 / 865 867 MHz frequency range.

SATELLINE-EASy, SATEL Compact-Proof and EASy-Proof supports additional to the original SATELLINE3AS data transfer also:

· Pacific Crest FST compatible data transfer over the air, if the opponent Pacific Crest modems operate in the transparent mode/FEC ON/Scrambling ON that is the most common setup among RTK applications. The other modes are currently not supported.

· TRIMTALK® 450s compatible data transfer over the air.

SATELLINE-EASy and SATEL Compact-Proof radio modem provides the following radio compatibility options:

· SATELLINE-3AS Original SATELLINE-3AS data transfer mode (Default)

· PacCrest-4FSK Transparent mode/FEC ON/Scrambling ON (Option 1)

· PacCrest-GMSK

Transparent mode/FEC ON/Scrambling ON (Option 2)

· TrimTalk450s(P)

Trimtalk450s GMSK Rx fitted to PacCrest transmitters (Option 3)

· TrimTalk450s(T)

Trimtalk450s GMSK Rx fitted to Trimble transmitters (Option 4)

· PacCrest-FST (Option 5)

Notes: Supported compatibility options may vary depending on the model and factory configuration.
All radio modems of a system must have identical FEC setting (ON or OFF) in SATELLINE-3AS mode.
The implementation of Radio compatibility options is based on the reference measurements and the available public data of the following radio modems manufactured by Pacific Crest Corporation: ADL, RFM96W, PDL HPB, PDL LPB. TRIMTALK is a trademark of Trimble Navigation Ltd.

7.13.1 Settings in compatibility modes

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0

In order to use the Pacific Crest/TRIMTALK modes implemented in SATELLINE modems:
PACIFIC CREST modems must have: · Protocol Mode · Transparent w/EOT Timeout (when using Pacific Crest modulations) · TrimTalk 450s (when using TRIMTALK GMSK modulation) · Modulation Type depends on the system · GMSK (default, always selected when using TRIMTALK 450s mode) · 4-Level-FSK · FEC = ON · Scrambling = ON · Data Security Code set to = 0 (=not used) · Local Address= 0...254 (0 by default) Pacific Crest modems receive messages from SATELLINE modems that have their TX1 address matching the Local Address.
Remote address=0...255 (255 by default, that is the broadcast address to be received by all). SATELLINE modems receive the message from a Pacific Crest radio, provided their RX1 address matches the Remote Address of a Pacific Crest transmitter (or if the message has the broadcast address 255).
SATELLINE modems must have the following key settings: · FEC OFF (because the FEC here means SATEL 3AS FEC, not Pacific Crest/TRIMTALK FEC) · Error check OFF · Full CRC16 check OFF · Radio Compatibility Option 1 in case of Pacific Crest 4FSK · Radio Compatibility Option 2 in case of Pacific Crest GMSK · Radio Compatibility Option 3 in case of TRIMTALK GMSK
When TX address is selected ON, then TX1 address is used like PDL Remote address that is the destination address for the transmitted messages. Default value is 0x00FF (=255) (note the hexadecimal format of the setting). When RX Address is selected ON, then RX1 address is used like PDL Local address. Default value is 0x0000 (=0) (note the hexadecimal format of the setting). Addresses are NOT applicable in TRIMTALK 450s mode so SATELLINE modems must have their RX/TX addresses OFF with Option3.
The configuration tools and settings are different between SATELLINE and Pacific Crest modems: Pacific Crest modems are configured via the serial port using PDLCONF WindowsTM program that sends binary control messages to the serial port of the modem. SATELLINE-EASy radio modems are configured via the serial port using any ordinary terminal program or SATEL Configuration Manager PC-program.

7.13.2 Repeater function

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0

The implemented Pacific Crest/TRIMTALK modes support also the repeater function. The repeater function is configured either by using the SL commands:
· "SL@M=R" (Repeater ON) · "SL@M=O" (Repeater OFF) or by selecting Repeater OFF/ON in the Additional setup-> Repeater programming menu.

Note 1. If error correction is ON (FEC ON) and TRIMTALK mode is activated by using "SL@S=3" command, the firmware automatically switches SATEL FEC OFF temporarily, and turns it back at the mode return.

7.13.3 Support for Local / Remote addresses
If the modem has TX address ON then primary TX address is handled in the same way as Remote address in Pacific Crest PDL modems. The default value is 0x00FF (255 in decimal format) i.e. the broadcast address.
If the modem has RX address ON then primary RX address is handled in the same way as PDL Local address in Pacific Crest PDL modems. The default value is 0x0000 (0 in decimal format). SATELLINE modem needs to have TX Delay 50ms or more in order to avoid messages from colliding in case it is to be placed in a Pacific Crest system that uses addressing and acknowledging scheme.
In case only broadcast messages are used (like in RTK applications) there is usually no need for TX Delay, except if the transfer delays identical to Pacific Crest modems are preferred in such cases an appropriate value of TX Delay is 34 ms.
Note 1. SATELLINE-modems do not support Pacific Crest retransmit/acknowledge scheme. However, that has no effect in RTK applications because they utilize only broadcast messages.

7.13.4 Transmission delays

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0

The original SATELLINE-3AS is the fastest mode the transfer delays are presented Appendix B.
In the PacCrest-4FSK, PacCrest-GMSK and Trimtalk450s modes the whole message is first read from the serial port. The end of the message is detected when there is a pause in data. After that data is framed and transmitted over the radio. Likewise the reception is done fully before outputting the message to the serial port.

8 TEST MODES

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0

The radio modem can be switched to the Test Mode in which it will send test messages on the radio. Test messages can be utilized for example when directing antennas during system installation. The transmitting radio modem needs only a power supply and an antenna in the test mode but no external terminal device.
If the test mode has been set ON, the radio modem starts to transmit test messages immediately after a reset or a power-up. Test messages are treated as normal data at the receiver side. The recommended data speed at the serial port of the receiving radio modem is 38400 bps @ 25 kHz radio channel or 19200 bps @ 12.5 kHz.
8.1 Short block test
In this test mode the radio modem sends a short test message that is preceded by a consecutive number and terminated by the Carriage Return and Line Feed characters. The test messages are repeated continuously at 1 second intervals. The short block test is suitable for running radio link tests. Reception of data can be monitored using a suitable terminal program.
Example of short data blocks: 00 This is a testline of SATELLINE-3AS radio modem 01 This is a testline of SATELLINE-3AS radio modem
8.2 Long block test
In this test mode the radio modem transmits a test message continuously for 50 s. After 10 s break the test transmission is started again. The transmission sequence is repeated continuously. The long block test can be used in order to measure the transmitter output power, standing wave ratio (SWR) of the antenna system or RSSI (Received Signal Strength Indicator) level at the receiver stations. RSSI can be monitored easily on the LCD display of the receiving modem or by using SL command "SL@R?".
Example of a long data blocks: 99 This is a long testline of SATELLINE-3AS radio modem 00 This is a long testline of SATELLINE-3AS radio modem
Note1. Green TD led indicates active test mode. Note2. Remember to set the test mode OFF before starting the normal data transfer. Note3. Message Routing and FCS must be disabled prior to setting the Test mode ON. Note4. The Test -modes are designed to be used in "SATELLINE-3AS" compatibility mode.

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0

The configuration of settings can be changed easily in several ways - the next chapters describe the details:
SATEL Configuration Manager PC software This clear to use software suits in most cases. Additional to other tools, it includes the channel list editor for creating the channel lists.
Programming mode menu When the radio modem is switched to Programming mode, it outputs a traditional text menu for the user input by using a terminal software (SaTerm, HyperTerminal, TeraTerm, etc.)
LCD menu & Push buttons (the models equipped with a display) The basic settings are accessible from LCD and push buttons. Some of the functions, for example the Channel list editing or configuration of Message routing is to be performed using PC software.
SURV firmware variant provides simplified/limited access to pre-set modem parameters. The firmware variant can be recognized from the "SURV" text in the modem FW-version information. Selectable parameters via LCD UI: channel (see Channel List for detailed information), compatibility, Repeater mode, FEC mode. NOTE! Channel list always ON! Please contact SATEL for additional information.
SL commands A terminal device can command or configure the radio modem by using special commands. SL commands are applied especially in cases where radio modems are to be integrated seamlessly inside a system behind the integrator's own user interface.

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0

13.1 SL command mode

When the SL commands are enabled there are possibilities that the user data may start with the characters "SL" which is handled as the SL command. This has caused the firmware to go to the continuous SL command search mode and any data has not been sent or even an "ERROR" acknowledgment has been received. To avoid this kind behavior the user can disable the SL commands. The SL commands can be disabled or enabled by using SL commands or toggling the "SL Command mode" parameter via the SATEL Configuration Manager, version v1.3.15 or newer.
By default the SL Command mode is set to ON. If the SL Command mode is set to OFF then the SL commands can be enabled or disabled by using the below described procedure. Regardless of original SL command setting state, changing the setting state with this procedure will effect to the reception process of the radio module. SL command setting state can be changed only via SATEL Configuration Manager in maintenance access level.
Radio can be set to Command mode separately with "+++" command, regardless of the set SL command mode (ON/OFF). Enabling the Command mode temporarily enables the SL command mode and disables the radio interface functions (Tx/Rx).
To enable the Command mode: · Send three "+" characters via serial port so that there is at least three bytes delay (according to Pause Length -setting) between each character. The response is "OK", when successfully set. <+><at least three bytes pause*><+><at least three bytes pause*><+>
To disable the Command mode: · Send three "-" characters via serial port so that there is at least three bytes delay (according to Pause Length -setting) between each character. The response is "OK", when successfully set. <-><at least three bytes pause*><-><at least three bytes pause*><->
*Pause Length -setting
Note! The "+ + +" and "- - -" procedures are not recommended to be used when radio is transmitting or receiving data (i.e. the application data occupies the TD or RD lines of the radio).

13.2 Changing parameters using the SL COMMANDS
The controlling terminal device can change the configuration settings of a radio modem. This is accomplished with the help of SL commands, which can be used during data transfer. SL commands can be used to change e.g. the frequency or addresses. It is also possible to interrogate a radio modem in order to gain information concerning current settings that are in use. The terminal device is either a PC or a programmable logic (PLC) together with suitable (terminal) program. SL commands must be enabled before they can be used. An SL command is a one continuous string of characters, which is separated from other data by pauses that are equal or greater than time defined by Pause length parameter in the set-up. No extra characters are allowed at the end of an SL command. Serial interface settings are the same as in data transfer and pin 12 of the serial connector MUST NOT be connected to ground (GND). SL command is properly recognised also in the case when the command string is terminated in <CR> (=ASCII character no. 13, Carriage Return, 0x0d) or <CR><LF> (<LF> = ASCII char. no. 10, Line Feed, 0x0a). If multiple SL commands are sent to the radio modem the next command can be given after receiving the response ("Ok" or "Error") of the proceeding command. In addition, it is recommended to implement a timeout to the terminal software for recovering the case when no response is received from the radio modem. When the power of a radio modem is switched off the configuration settings of a radio modem always return to values defined initially using the Programming Mode, thus resetting any settings changed using SL commands during power on. It is however possible to save settings changed by using SL commands and to make them the new configuration settings. The radio modem will acknowledge all commands by returning an "OK" (command carried out or accepted) or the requested value, or an "ERROR" (command not carried out or interpreted as erroneous) message.
CR/LF characters are added to end the response messages (unless they are already present) in order to make parsing easier. Settings can be toggled, SL Commands ON/OFF, CR/LF ON/OFF. In case you need more information on the time delays related to the use of SL commands, please contact the manufacturer. In order to get information of the latest and/or special SL commands please contact SATEL.

User Guide, Version 10.0

A list of predefined radio channels can be stored in the memory in order to change the radio settings simply by switching between the channels. Each channel carries the following info:
· Channel number (any number -32767...32767) · Transmitter/Receiver frequency · Channel width (12.5, 20 or 25 kHz) · Transmitter power level (optional) Additionally, the default channel that the radio modem uses after a reset is defined.
Channel lists can be created and utilized by using either SATEL Configuration Manager Software or SL commands.
SATEL Configuration Manager software provide a channel list editor (snapshot below) for creating and saving a channel list in the radio modem, or in a file for later usage.

SL commands provide an interface for a host device to command the radio modem directly. An example of the procedure for creating or replacing a channel list:
1. Clear existing channel list (SL$C=0) 2. Set channel info for each of the channels to be created starting from index 0 (SL$L=) 3. Set number of channels in channel list (SL$C=) 4. Set the default channel (SL$D=) 5. Verify the new configuration: Get number of channels in channel list (SL$C?) Get channel info for each of the channels (SL$L?) Get the default channel (SL$C?) 7. Enable Channel list (SL$M=1) in order to activate the Channel list 8. Save the settings (SL**>)
Note. "SURV" firmware variants of SATELLINE-EASy radio modems equipped with LCD display provide an easy-to-use channel selection on LCD by using push buttons.

15 REPEATER MODE AND ADDRESSING
Repeaters and addressing may be used to extend the coverage area of a radio modem network, and to direct messages to selected radio modems in the network. In large systems, with several repeaters and formed repeater chains, it is often practical to use routing instead of plain addresses.
15.1 Repeater
In circumstances where it is necessary to extend the coverage area of a radio modem network, modem can be used as repeater stations.
The maximum size of a repeated data packet is 1kB (kilobyte). The Repeater Function is switched on using the Programming Mode. In the repeater mode the radio modem will function as a totally independent unit, which means that only a power supply and a suitable antenna are needed. Other devices are not necessary.
A radio modem acting as a repeater can also be used to receive and transmit data. In repeater mode the radio modem will transmit the received data to the serial interface in a normal fashion. The difference being that the received data will be buffered into the buffer memory. After reception the radio modem will re-transmit the buffered data using the same radio channel as in reception. Data received through the serial interface a radio modem in repeater mode will transmit normally.
The same network may include several repeaters, which operate under the same base station. Repeaters may also be chained; in which case a message is transmitted through several repeaters. In systems with more than one serially or parallelly chained repeater, addressing or routing protocol must be used to prevent a message ending up in a loop formed by repeaters, and to ensure that the message finally reaches only the intended radio modem.

15.2 Addressing

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0

Addresses can be used to route a data message to the desired destination or to separate two parallel networks from each other. In networks with repeaters it is usually necessary to use addresses to prevent data messages from ending up in loops formed by repeaters. In case of setting the "Message Routing" function in use, Tx / Rx addresses are ignored by the modem.

Modem allows the use of individual addresses both for reception and transmission. Addresses can be switched on separately, or simultaneously, in both data transfer directions.

The radio modem contains two transmission and two reception addresses, which are knows as the primary address and secondary address. The primary address is used whenever data from the serial interface is transmitted. At the receiving end, the radio modem will receive using either of the two receive addresses.

Secondary transmit address is only used in repeater applications.

Radio modems configured to function as repeaters, will repeat data messages using either the primary or secondary address, depending upon which address was used during the reception of the data message.

If only one address pair is needed in a network, both addresses must be set the same (TX1 = TX2 and RX1 = RX2).

It is also possible to transfer the received address onto the serial interface.

The address is composed of two characters totalling 16 bits, resulting in over 65,000 different address combinations. The address is attached to the beginning of each data packet sent by the radio modem. When a radio modem receives a data packet whilst using addressing mode, the radio modem will check the first two characters of each received data packet to ensure that the packet in question was intended for the correct radio modem.

ADD H ADD L

DATA

Address may be selected between 0000h...FFFFh (h = hexadecimal, corresponding decimal numbers are 0-65535).

Example: address 1234h (4660 in decimal format), where 12h is ADD H and 34h is ADD L.

Example: address ABFFh (44031 in decimal format), where ABh is ADD H and FFh is ADD L.

Address Data

Data

Transmission address has been set OFF. Radio modem will transmit the data packet as such.
Reception:

Transmission addressing has been set ON. The radio modem will add the primary TX address to the beginning of the data packet.

Reception addressing has been set ON and either the primary or secondary RX address of the radio modem is identical to the address of the received data packet.
The radio modem will remove the address and send the actual data to the RS-232 interface.
However, if the "RX Address to RD-line" setting is on, the radio modem does not remove the address.

Reception addressing has been set ON, but both the primary and secondary RX addresses of the radio modem are different from the address of the received data packet.
Data does not appear on the RS-232 interface.

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0

Reception addressing has been set OFF.
The radio modem will transfer all received data to the RS-232 -interface.

Reception addressing has been set OFF.
The radio modem will consider the characters of the address as a part of the data and will send all the characters to the RS-232 interface.

Reception addressing has been set ON but there is no address in the data packet.
Data will appear on the RS232 interface ONLY if the first 2 characters of the data match either of its own RX address. The radio modem will remove those 2 characters of data.

15.2.1 Connection between two points
When forming a connection between two points it is recommended that both the reception and transmission addresses are identical in both radio modems. This is the easiest way to control addresses and the risk caused by interference from other systems operating in the same area is minimal.
Example: by setting all addresses of both radio modems to a value ´1234´, they will accept only those messages which contain this address, and they will use this same value when transmitting data.
If the channel is reserved for use only by the single network, or if the terminal devices are responsible for addressing, it is not necessary to use addressing in the radio modems.
15.2.2 System of one base station and several substations
In systems with several substations, the base station must know to which substation each message is intended, and from which substation each received message originates. Usually terminal devices handle addressing completely, but it is also possible to use the addressing functionality of the radio modems.
For example, if the substation terminal devices are not able to check and form addresses by themselves, addressing may be achieved with the help of the addresses of the radio modems attached to these terminal devices. The base station may, in such a case, define the destination of a message by adding the address of the corresponding radio modem into the beginning of the data packet. The substation radio modem(s) will check the address and the corresponding radio modem will identify and remove the
75

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0
address characters. In a similar way, the substation will add when transmitting to the base station its address characters into the beginning of the data packet, thus defining the origin of the sent data packet. In the base station radio modem, addresses have been switched OFF, so that they are transmitted as is to the base station terminal device for further processing.

15.3 Using repeaters and addresses in the same system
In systems with several repeaters, a substation and a base-station, addresses must be used in radio modems. It is possible to realise also a system with only one repeater without addressing. In such a case, the base station will however hear the message both from the substation and from the repeater, in other words the message is duplicated as it moves along the route.
There are at least two ways of realising such a system depending on the capabilities of the terminal devices in question and on the number of repeaters to be used and on their relative positions to each other.

15.3.1 System with several repeaters
In systems with several serial or parallel-chained repeaters, addressing must be used to prevent messages from ending up in loops otherwise formed by repeaters, and to ensure that only the desired (addressed) radio modem receives the data intended for it.
All radio modems in the network must be set to a state, in which the RX-addressing is switched ON and TX-addressing is switched OFF. Base-station and all substations add an address string in the beginning of the data to be transmitted. In the relaying of the message addressing is used in the following way:

R1 ADD R2 ADD S ADD

DATA

- The above is the data received from the base station terminal device, containing repeater addresses (R1 ADD, R2 ADD) and the substation address (S ADD). Two characters define each address.

R2 ADD S ADD

DATA

- The above is the same message after being relayed from repeater 1 to repeater 2.

S ADD

DATA

- The above is the same message after being relayed from the last repeater in the chain (repeater 2) to the substation.

DATA

- The above is the same message being relayed via the serial interface of the substation radio modem to the terminal device.

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0
In a situation where the substation transmits data towards the base-station the address is formed in a similar way, but the order of the addresses is reversed:

R2 ADD R1 ADD M ADD

DATA

-In the above, R2 ADD is address of repeater 2, R1 ADD is address of repeater 1 and M ADD is the address of the base-station.

15.3.2 Repeater chain using address pairs

In a situation where the terminal devices and substations cannot form address fields, but are able to recognise messages addressed to them, alternating address pairs may be used. Transmit address (TX) and receive address (RX) alternate in the order shown in the table below.

Address type
TX-address RX-address

Base-station address
Address 1 Address 2

Repeater 1 and the addresses of the substations of the base-station
Address 2 Address 1

Repeater 1 substations addresses
Address 1 Address 2

In a network where alternating addresses are utilised, the exact route that is used to relay a message to a certain radio modem is fixed at the time of installation and configuring the system. The order of the addresses must be the same as the order of the route that is used to relay the message to the radio modem. It should be noted however, that in networks where alternating addresses are used the basestation and substations will hear their own messages repeated.
15.3.3 Repeater chain using dual addressing
If the terminal devices cannot add address chains to the beginning of the data packets, a network with several repeaters may still be realised by using dual addressing. In dual addressing each link (see arrows below in figure) is given a unique address, which will prevent duplication of messages and endless loops in the network. The terminal devices need not add anything to the data.
Usually the primary transmit address is used in transmission (TX1). The secondary transmit address (TX2) is used only if the Repeater Mode is used and the packet to be repeated was received using the secondary reception address (RX2).
In the following example two repeaters are used. It should be noted that each link (arrow) might be uniquely defined with the help of radio modem numbers and data transfer directions. The Repeater Mode should be switched ON only in the radio modems acting as repeaters to prevent the packets from remaining in endless loops in the network. Repeaters may also act as ordinary substations; in that case the terminal device must wait until the message has reached the end of the repeater chain before sending data.

15.3.4 Redundant repeater chain
Reliability of a radio data communication system can be improved significantly by designing redundant equipment setup for master and repeater stations. The two repeater chains are separated by proper dual addressing setup. Slave stations need to be able to communicate with the master through the both repeater chains. By using the "TX address auto switch" function, the slave station modem directs the reply message to the repeater chain from which the request has been received.
If "TX address auto switch" has been set ON, radio modem checks out the RX address of the received message. When one of the RX addresses is recognised, all the messages coming in from the serial interface will be sent to the air with matching TX address. The use of "TX address auto switch" function is not recommended if Repeater Function is set ON.

16.1 Introduction to Message Routing

Message Routing is an exciting feature in radio modem. This feature allows messages from terminal devices to be automatically routed over the radio modem network to a specified recipient terminal.

In brief, the Message Routing works as follows: First, a radio modem reads any message coming from the terminal(s) attached to it. The radio modem detects the terminal address of the recipient, by seeking a pre-set position inside the message for the address. The radio modem checks its internal route table to see, if there is route information corresponding the address it has just found. The radio modem transmits a radio frame, which includes the network id (see later) the route information the original user message encapsulated redundant information such as checksums for error checking etc. The radio modems along the route relay the frame over the network to the radio modem at the destination. The radio modem at the destination first checks the validity of the received radio frame, then extracts the original user message, and finally outputs it the terminal device attached to it.

The figure left illustrates a possible structure of a

radio modem network.

Terminals are usually PLC devices that send and receive messages according to a specific user protocol.

Note: The term repeater used in the context of the Message Routing should not be mixed with the Repeater Mode, which is a feature independent from the Message Routing.

Features of Message Routing

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0

The Message Routing feature of the modem is designed to be a fast and transparent to fit real time systems. The features include:
· Transparent to user protocols. · Easy construction of a network containing several repeaters. · Any radio modem may operate as a repeater, i.e. dedicated repeaters are not usually needed
thus cutting down on costs. · Large areas of coverage may be implemented by using only one radio channel. · The use of mobile substations is also possible to some extent. · The system will be fully deterministic i.e. the transmission delays are predictable. Because of
that, the principle of Message Routing is connectionless. · Added redundancy, as a failing radio modem can be, in certain cases, bypassed with another
radio modem positioned in the same coverage area. · Message Routing is intended mainly for the protocols based on polling scheme and a single
master station.

16.1.1 Limitations of Message Routing
· It is assumed that the position of the address field in the user messages is fixed. However some special protocols are supported: o IEC 60870-5-101 is a protocol commonly used in control applications of power lines. o RP570 protocol
· The message cannot end to the address; there must be at least one character after the address. · It is assumed that there is only one message at a time inside the network simultaneous messages
could cause collisions. · The max number of the routes depends on the actual hardware and the Firmware version. · Operation of the Tx / Rx addresses is automatically blocked in the case of switching the "Message
Routing" function on.

16.1.2 Getting started with Message Routing
The design of any radio modem system requires very precise planning. Once the choices between devices, their location, installation, maintenance etc. are clear, the Message Routing for the system can be implemented.
Planning your Message Routing System 1. Decide which mode of the Message Routing suits the system - Source Mode or Virtual Mode. See the following paragraphs for details. 2. Design a layout of the system describing the settings such as protocol, addresses of the terminal equipment, radio frequencies and so on. 3. Configure the radio modems accordingly. There are two ways to configure the parameters related to the Message Routing: SaTerm PC-program Manual configuration in the setup menu. In either case, please check the chapter on Settings before changing the setup of the radio modems. Finally, when all the radio modems have correct settings, they are ready for further installation.

User Guide, Version 10.0
16.1.3 SaTerm and the configuration of the Message Routing SaTerm is a PC based program that allows the user to design their required network simply and quickly using a graphical interface to literally draw the network plan on the screen. Firstly, a picture of the network is created to show all the radio modems and the intended route that the data is to take. Secondly, the required settings are defined in the drawing. Finally, the setup of each actual radio modem can be uploaded by connecting the actual radio modems one by one to the COM port, switching them to the programming mode, and clicking the transmit button of SaTerm. Please check the user manual of SaTerm for more details. The figure below shows a snapshot of a typical routing window taken from SaTerm screen.
16.1.4 Manual configuration of the Message Routing The radio modems can be configured manually via the programming menu. However, this is recommended only if the structure of the network is very simple, or if it is desirable to define such special functions that are not possible to draw using the graphical interface of SaTerm. Examples of such cases are for example non tree-structured networks, or the use of same repeaters in several overlapping networks. The operation of the Message Routing must be clearly understood before configuring the radio modems manually.

User Guide, Version 10.0
16.1.5 Configuration of the protocol in Message Routing
A radio modem will detect the presence of an address used by inspecting the protocol from the message received via the serial interface. On the basis of this user address, all necessary information needed to relay the message to destination is fetched from an internal routing table inside a radio modem. The user protocol is not interpreted; instead, the user address is searched according to its location in the message. The beginning of the packet is located by a preceding pause in the byte stream. Message Routing can therefore be applied to most protocols with fixed address field position.
The position and length of the address is defined by two settings: Offset and Length. · Offset defines the number of bytes (0...15) preceding the address. · Length is the length of the address in the user protocol expressed in bytes (1...4).

O ffset

Length
USER ADDRESS

Byte length Start of data packet, Offset=2, Length=3

USER DATA

A transmitting radio modem adds a routing header and a tail to the user message. Consequently, a radio modem that receives the message removes the header and tail - so the Message Routing scheme is transparent to the user protocol.

16.3 Detailed description of Message Routing
16.3.1 Source Mode Routing
The above figure represents a network containing four (4) radio modems. Each radio modem is given a unique address (0...3). A terminal device has been attached to the three of the four radio modems and they communicate with each other using terminal addresses X, Y and Z, respectively. Radio modem 0 and terminal device X together constitute the base station of the network and all routing information of the network has been programmed into this base station.
When the terminal device X transmits a packet to (e.g.) terminal Y, radio modem 0 will detect the address Y from the data received through the serial port. From the routing table a route 1,2 can be found to which the radio modem also adds its own address to define the route for return data. Radio modem 1 repeats the packet and radio modem 2 removes the address information from the received data packet thereby transferring only the original data to the serial interface. The address information received together with the packet is reversed (2, 1, 0) and saved to be used in the transmission of subsequent reply packets.
16.3.2 Virtual Mode Routing

When using repeaters, the same packet is sent via a (radio) channel several times. A radio modem situated in the repeater chain will often hear other radio modems in addition to the immediate neighbouring radio modems. With Source Mode Routing the complete address information is sent

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0 together with the packets enabling the use of these secondary routes. Usually repeaters have better antennas (and/or antennas placed higher) than normal substations, which means that the distance between two repeaters can be much longer than the distance between a repeater and a substation. Connections to other than the neighbouring stations of the repeater are not necessarily reliable under all possible (radio) conditions, but they can often be used to keep the network up and running at least partially should a repeater somewhere in the middle of the chain fail. In addition to this, the likelihood of a transmission error decreases if it is possible to listen to more than one transmission since; in this case, it is more likely that at least one of them will be received error-free. It is also possible, that the radio connection is asymmetrical due to the greater output power of a repeater or due to local interference, in which case, data can in fact travel in opposite directions using different routes. When a repeater receives a message that contains its address but not as the first address in the address field, the packet is stored in a buffer. If the relayed message from the repeater, and the modem having sent the message originally, is not received (due for example, because of radio modem failure or if it has an erroneous checksum), the packet already buffered into the memory is re-sent without any change to the timing (no additional delays are introduced). Because of this, relatively short hop distances can be used, without the likelihood of errors being increasing due to the added number of repeats. A possible error in one of the repeaters does not necessarily cause a total breakdown of traffic.
R1 M
R2
The overhop function allows for the use of mobile substations. In the example above, a mobile substation is first located in the coverage area of repeater R2. The route is defined as M, R1, R2 and vehicle. When the vehicle moves to the coverage area of repeater R1, the radio modem picks the packet already from the transmission of R1. This is then transferred to the serial port using an additional delay, so that the timing does not differ from the first situation where the radio modem of the vehicle was in the coverage area of repeater R2. In this way a collision of the reply transmission and the transmission by repeater R2 is prevented. When the mobile station is transmitting, it is enough that at least one radio modem defined to be a part of the route receives the transmission.

User Guide, Version 10.0

Electronic devices are sensitive to external influences which should be taken into consideration while taking the device into operation. Proper place for assembling is necessary for good performance and long lifespan. Even though the modems are built to whit stand external vibrations, shocks, temperature fluctuations and high/low temperatures still those occurrences should be avoided as much as possible to maximize the durability and longevity of the products. High temperature decreases the lifespan of the components whereas vibration and shocks weaken the mechanical structure and can drastically affect the performance in use.
Should be noted that SATELLINE-EASy is not meant for direct outdoor use and to avoid moisture or high humidity issues EASy modem is preferable to use only indoors or outside inside of proper isolation against harsh weather conditions.

It is recommended to connect a ground wire from the grounding terminal to the earth ground and that all other interconnected devices share the same electrical ground potential.
Besides the mains voltage safety, proper grounding is essential also for the error free operation of radio links and the protection against over-voltages and lightning. Although SATEL EASy-Proof incorporates a robust internal surge protection, the surge spikes and power transients caused by lightning, ESD or other electrical systems must be discharged to earth ground.
17.1.7 Grounding cable and screws Grounding cable should be with >1 mm2 copper conductor with insulation, preferable green/yellow coded for easy ground recognition. Cable should be joined to grounding connector by crimp connection (pictured). Grounding should be terminated to a grounding rail or other reliable grounding source with shortest possible cable length to avoid ground loops and elevated resistances in cables. If longer cable is needed, cable thickness should be increased accordingly. Two different screw types are included in the installation kit. Screw type A is M3 countersunk screw and is used to attach the installation plate to the modem housing. Screw type B is used for grounding connector attachment.

User Guide, Version 10.0

Grounding the antenna is recommended when antenna is located outside on a mast or long pole where it is prone to lightning strikes or other high energy disturbances. Grounding is best to locate as near as possible to the expected disturbance to occur, in practise at the point where the antenna is fixed to a structure. Wiring the antenna ground and/or cable shield should be done to a ground rail or other reliable common ground with shortest possible cable length to avoid high resistance ground loops. If grounding cable is needed to be longer thicker cable should be used accordingly. Copper cable is preferred for highest conductivity. It is not recommended to use the mast only as a grounding conductor as its conductivity can't be always guaranteed.

The connectors and the names of the signals are NOT defined. Different RS-485/422 standards or proprietary buses specify different names for the wires. Common signal names used are `A' and `B', `+' and `-' or `hot' and `cold'. Unfortunately these names define the polarity of the signals only for a specific system or specific equipment. In reality `A' of one system can actually be `B' of another. If the polarity is wrong, the data will be inverted. Usually the simplest way to solve the issue is the trial and error method, as RS-485 signals can be connected only two ways.

17.3 Antenna installation

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0

17.3.1 Hand-held equipment

· ¼-wave antenna (wavelength at frequency of 450 MHz is approximately 70 cm) · Helix-antenna
Antennas are installed directly to the TNC connector at the upper part of the radio modem.

17.3.2 Mobile equipment
· ¼-wave antenna · ½-wave antenna
The ideal installation position is vertical, and there should be at least 0.5 m of free space around the antenna. A separate ground plane should be placed under the ¼-wave antenna (vehicle rooftop or the engine hood or trunk door are usually suitable). In problematic cases the most suitable type is a ½-wave antenna. It can be installed directly at the top of a pipe with the added benefit of gaining as much as free space around the antenna as possible. In case the antenna cannot be directly connected to the radio modem, a coaxial cable with 50 ohm impedance must be used between the antenna and the antenna connector.
17.3.3 Base stations
· Omni-directional antennas ( ¼- , ½- or 5/8-wave antenna) · Directional antennas (yagi /multi-element antenna or corner antenna)
The antenna should be installed in a vertical position. The exact location of the antenna depends on several factors, such as the size of the overall system and the coverage area terrain contours. A rule of thumb is that the base station antenna should be located at the highest point of the coverage area and as close to the centre of the coverage area as possible. The base station antenna can also be located inside a building, if the walls of the building do not contain metal.
17.3.4 General antenna installation instructions
The reliability and the achievable coverage of useful signal strength can be severely affected by the positioning of the antenna. Antenna and cable connectors should have gold-plated pins and sockets, as use of low quality connectors can lead to eventual oxidation of the connector surfaces, which in turn may degrade the contact and cause additional attenuation. Good quality tools and materials must be used when installing radio modems, antennas and cables. The weather tolerance of the materials used must also be taken into account. Installed materials must withstand all foreseeable weather conditions (frost, excess sun, direct UV-radiation, seawater etc.). Also possible environmental pollution must be considered (acids, ozone etc.). Antennas must be installed well away from metallic objects. In the case of small antennas this distance should be at least ½ m. With large antennas the distance should be >5 m and in case of repeater antenna combinations >10 m.

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0
If the system contains a large number of radio modems, the best location for an antenna is the highest point of a building and possibly an additional antenna mast. If a separate antenna mast is used, the antenna can, if necessary, be installed sideways about 2...3 m from the mast itself.
When installing an antenna possible interference sources must be considered. Such interference sources are, for example:
· mobile telephone network base station antennas · public telephone network base station antennas · television broadcast antennas · radio relay antennas · other radio modem systems · PC-related devices (approximately 5 m radius from antenna)
Please note that antennas are always tuned to a specific frequency range when ordering them. Simple antennas and antennas, which have been constructed of stacked yagi-antennas, are typically rather broadband. As the number of yagi-elements increases the frequency range becomes narrower.
When designing and installing a system it is advisable to prepare to test the system, and also to consider serviceability of the system. In particular cabling should be planned to allow easy access and to allow for maintenance. It is often practical to use long antenna cables, so that the radio modem can be installed far enough from the antenna itself to a location that is easily accessible.
The type of the antenna cable is dependent on the length of the antenna cable, and the following table can be used to select a suitable type:

Length <5m >20m >20m

Type RG58 ECOFLEX10 ECOFLEX15

Attenuation 10m/450MHz 3.0dB 0.9dB 0.6dB

If there is a line-of-sight path between the antennas a 6 dB power marginal is usually adequate. However, if the connection is built on the reflection and/or the knife-edge diffraction the path loss can vary even 20 dB depending on the weather conditions. In this case a short test can give a too positive result of the quality of the connection. Thus the height of the antennas and topographical obstacles must be surveyed with great care. From time to time a marginal connection can be used if the data transmission protocol is well prepared for this and the data transmission that occasionally slows down does not cause any problems to the system.
Vertical polarised antennas (antenna elements are in vertical position) are often used in radio systems. In a system between a base station and substations vertical polarisation is recommended. The radio modem antenna cannot be mounted on the same level as the other substation antennas in the same building. The best way to distinguish from the other antennas situated in the neighbourhood is to mount the antennas as far as possible from each other on the altitude level. The best result is generally obtained when all the antennas are in the same mast. With an extra ground plane between the antennas more distinction can be obtained between the antennas in the mast.
Horizontal polarisation can be used in data transmission between two points. With the polarisation attenuation more distinction is obtained to vertical polarised systems. The influence of the directional

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0
patterns of the antennas must, however, be taken into consideration. If a distinction to another interfering antenna is wanted with the horizontal polarised antennas there must be a good attenuation of the back lobe. In addition to this the interfering radiator should be situated behind the antenna.
When a system does not demand the use of an omni-directional antenna it is recommended that directional antennas are used e.g. two-element yagis in permanent external installations. Please note that as antenna amplification increases the setting of the direction of the antenna requires more attention.
Base stations in high places should be supplied with high-Q cavity filters. Please note that the higher the base station antenna, the larger the coverage area and in turn that the risk of interference is also increased.
SATEL recommends the use of a band-pass filter with a large Q in the antenna cable of the base station.
Example of an antenna installation: Long connection distances can be realised by using amplifying antennas (G=Gain) and by installing the antenna high.

18.1 Factors affecting the quality and distance of the radio
connection
· power of the radio transmitter · sensitivity of the radio receiver · tolerance of spurious radiation's of the radio modulating signal · amplification of transmitting and receiving antennas · antenna cable attenuation · antenna height · natural obstacles · interference caused by other electrical equipment
The transmitter power of the modems using 330 420 / 403 473 MHz frequency range is 1 W (maximum) and the sensitivity of the receiver better than -115 dBm. Thus in a flat area and in free space with a 1/4 wave antenna (antenna amplification 1dBi) and antenna height of 1 m communication distances of 3 to 4 km can be achieved. Distances may be considerably shorter in situations where there are metallic walls or other material inhibiting the propagation of radio waves.
Over long distances, increasing the height of antennas can often solve problems caused by natural obstacles. A ten-fold increase in distance can be achieved with the use of amplifying antennas. Frequent topographical variations over long distances may require that at least one of the antennas be raised to a height of 10 to 20 m.
If the antenna cable is more than 10 meters long it is necessary to use a low loss cable (< 0.7 dB /10 m) in order not to waste the antenna amplification. Adding a repeater station can also solve problematical radio connections. In systems with many base stations the RSSI-signal can be used to assist in choosing the base station with the best signal. A communications network can also be built with a combination of cables and radio data modems.
Modem tolerates normal levels of interference that occur. However, exceptionally high levels of interference can break through the safeguards and thus cause errors in data transfer. In mobile vehicle applications the range of operation can be increased by dividing the transmitted data into e.g. 50...500 byte long blocks and by re-transmitting the defected blocks.
A sufficient safety margin can be obtained by testing the communication path using extra 6 dB attenuation at the antenna connection and with slightly less effective antennas than those to be used in the final system.

18.2 Radio field strength

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0

Radio signal strength must be good enough for successful data transfer. Where field strength is above a certain level, the operational results are very good. Below this level, a few dB marginal areas occur in which errors begin to be generated by noise and interference that will eventually lead to loss of connection.
The field strength is at its optimum level in open space, although increasing distance will still reduce it. It must also be remembered that one open space has different environmental and external factors to another, and that the effects on transmission quality must be taken into account when planning the system.
Ground, ground contours and buildings cause attenuation (loss of energy through absorption) and reflection of radio waves. Buildings reflect radio waves and therefore the effects of attenuation are not as acute when transmission is over a short distance.
However, the reflected waves will often be a bit delayed, and when they combine with the direct radio waves they interact in either a weakening or a strengthening way. This causes the fading effect in mobile systems. In reality very sharp signal drops spaced about 35 cm apart may occur. The attenuation may even reach 40 dB, normally less.

19 CHECK LIST

SATELLINE-EASy / -EASy 869 / SATEL Compact-Proof / SATEL EASy-Proof
User Guide, Version 10.0

The following points must be taken into account when installing and configuring a radio modem:
1. All operating voltages of all the equipment concerned must always be switched OFF before connecting the serial interface cable.
2. When considering the exact placement of a radio modem and/or its antenna, the following points must be taken into account to guarantee optimal results:
· The antenna should be installed in open space as far as possible from any possible sources of interference
· The radio modem should not be installed onto a strongly vibrating surface
· The radio modem should be installed in such a way as to minimise exposure to direct sunlight or excessive humidity.
3. To ensure reliable operation the voltage output of the power supply must be stable enough and the current capability of the power supply must be sufficient.
4. The antenna must be installed according to instructions.
5. Serial interface settings between the radio modem and the terminal unit must correspond to each other.
6. All radio modems in the same system must be configured using same settings (radio frequency, channel spacing and data field length).
