USE OF CELLULAR NETWORKS – IMPORTANT NOTES

Avanoa o SMS
Most Multilog2 models include the ability to communicate to a server via use of the cellular data network. This is usually via the regular data network (which gives internet access). Alternatively, the SMS (Short Message Service) messaging can be used; in most cases this will be as a fall-back if the logger is temporarily unable to access the regular data network. If configured for SMS use, the logger uses the available 2G network.

Taua: 2G (GPRS) services, which carry the SMS messaging system, are slowly being turned off around the globe. Once 2G is switched off, the SMS services available within the logger will no longer be able to function. Unless deactivated in the logger settings, the logger will continue to try, wasting battery power. Therefore, check with your cellular network operator for their switch off date before setting the logger to use the SMS backup service or any other feature requiring SMS use.

To deactivate the use of the SMS system, any related SMS settings must be removed (switched off or deleted). Refer to the IDT User Guide for details of SMS settings.
Any modified settings must be saved to the logger.

Fa'aaliga: For use of SMS services, both the logger and the cellular network provider must support SMS. In addition, the SIM card fitted inside the logger must support SMS use. (Check with your SIM supplier if required).

Choosing which version to use
The IDT software tool provides a user-interface to the logger. It can be used for checking or making adjustments to the logger settings and for testing the logger operation within its installed site. Prior to IDT being able to perform these functions, it has to ‘connect to’ the logger; this simply means that the two end devices (logger software and IDT software) are able to communicate with each other over a working communications path.
IDT is available in three versions:

IDT for PCs having a Windows-operating system.
IDT for mobile devices (phones and tablets) having an Android operating system.

IDT for mobile devices (phones and tablets) having an (Apple) iOS system.

The latter two are referred to as the ‘IDT app’, whereas the first is referred to as ‘IDT (PC)’ or ‘IDT (Windows)’.

It is recommended to install and use the IDT app version whenever possible; it covers most types of HWM loggers. There are, however, a small number of situations where loggers or logger/sensor combinations that (at the time of writing) require the use of the IDT (PC) tool. Refer to section 8 for further details of which sensors or features require IDT (PC), as applicable to the loggers listed in section 1.1.

LOGGER DEVICE OVERVIEW

VAEGA FAALETINO & FA'AALIGA SOSE
The Multilog2 logger family is flexible in design and can be built to suit a variety of uses. It has a metal enclosure and is of a waterproof construction, using a seal to keep out water.
O se tasiample fa'aalia i le Ata 1.
The logger is powered by a non-rechargeable Lithium battery. The life of the battery can vary with its orientation; refer to Figure 1 for the orientation that will give best battery life.
The top of the logger includes a handle, used for carrying the unit. It also provides a convenient way of hanging the unit in its correct orientation using wall-mounted brackets or other fixing methods.
O lo'o iai fa'ailoga eseese i luga o le logger. E aofia ai:

The nameplate label, which includes the logger part-number, its serial number, and an ‘SMS number’ (an identifier for the logger, in the form of a telephone number).
Fa'ailoga fa'amatalaga fa'afeso'ota'i.

The logger has waterproof electrical connectors for attaching sensors and the antenna. These can be present on two surfaces (top and bottom). The interfaces installed, and their position, will vary between model-number supplied. Follow the labels to identify interfaces.
A pressure interface may also employ a built-in pressure transducer with a quick-release connector. This is for direct connection to a pipe (or hose).

MA'A I FAFO (FILIFILI)
Most Multilog2 models have a connector that allows an External Battery to be connected. These provide the logger with additional power capacity.
O se tasiample fa'aalia i le Ata 2.
E avanoa ma'a eseese.
Always use HWM supplied batteries to ensure compatibility and safety. Ensure the cable supplied with the battery is suitable for the external power connector fitted to your logger. (6-pin and 10-pin connector versions are available. See also section 2.7).

(For situations where the use of an external battery is required, seek the advice of your HWM representative).

LOGGER GALUEGA

The logger software is designed to minimize battery use and thereby prolong the expected battery life. However, battery life is also affected by user-programmablesettings. The user is advised to set the logger tasks and sample alaleo i tulaga aupito maualalo o le faaaogaina faamoemoeina ina ia pulea lelei le malosi maa.
Pe a tu'uina atu, e fa'aaoga le malosiaga o le maa i fafo e fa'alautele ai le ola o le maa o le logger po'o le fa'ataga o feso'ota'iga fa'atele ma le 'au'aunaga talimalo.
O le logger e masani lava ona lafo mai le falegaosimea i se tulaga le toaga (fa'asino i le
'tulaga uta', po'o le 'tulaga moe') e fa'asaoina ai le ola o le maa.

When activated (see section 3), the logger will initially go into the state of “Waiting” (for a short time). Then it will go into the state of “Recording” and begin repetitive logging of measurements from the various sensors fitted to the unit, according to its configuration and settings.
O lo'o fa'agaoioia le logger e fa'aaoga ai taimi e lua, ua ta'ua o le “sample vaitaimi” ma le “vaitaimi o faamaumauga”. O le a sample masini i le sample fua faatatau e faia fua le tumau samples; ose galuega tala'i fai soo. Ina ua uma ona faia ni fua sample mea, o nisi o galuega fa'afuainumera e mafai ona fa'aoga filifiliga e maua ai se fa'amaumauga o lo'o fa'amauina (fa'asaoina) i le fua fa'atatau; o nei mea e fai ai fua fa'amaumauina ma fa'asaoina i totonu o se vaega e manatua ai e ta'ua o le "fa'amaumauga muamua". Ole taimi ole ogalaau e masani lava ole fa'atele ole sample vaitaimi.

The logger will also have daily tasks at set times, such as uploading its unsent data over the internet. When sending data, the logger waits to receive confirmation from the server that the data was received without error; If confirmation is not received, it will re-send the data at the next call-in time.
O le logger e mafai ona faʻapipiʻiina e mataʻituina faʻamaumauga mo nisi faʻasologa poʻo tulaga ma e mafai ona lafo se feʻau pe a tatau ona iloa se fetaui.

E mafai ona lafo le fe'au i le 'au'aunaga (le nofoaga masani) po'o se isi masini.

FA'AVAE LE LOGIG (FILIFILI)
Section 2.3 gave a description of logger operation that is available as standard on most Multilog2 logger models; The logger normally samples fa'amaumauga i le seti sample vaitaimi, ma fa'amaumau fa'amaumauga i le taimi fa'atulagaina o fa'amaumauga. Ae ui i lea, o nisi o faʻataʻitaʻiga e ofoina atu filifiliga mo le faia o faʻamaumauga faaopoopo (o faʻamaumauga faʻamaumauga) i luga atu-nai lo masani sampfua faatatau. O fa'amatalaga fa'aopoopo o lo'o fa'amauina i totonu o le vaega e manatua ai le "fa'amaumauga lona lua".
These features are sometimes referred to as “Enhanced Network” logging and “Pressure Transient” logging; Collectively they are referred to as “Fast Logging”. The ‘Enhanced Network’ and ‘Pressure Transient’ loggers (both being based on the Multilog2 design), have the named option available as standard.

Fa'aaliga: The feature can only be installed by the factory at the time of build. The options must therefore be specified at the time of ordering, along with the required maximum sampfua faatatau ling.

COMMUNICATIONS INTERFACES AND PROGRAMMING CABLES
To communicate with the Multilog2 logger, a programming cable is required. There are two connector options available in the logger family for making this connection (10-pin or 6-pin); only one of these alternatives will be fitted. Use a programming cable that matches the connector type on the logger.
On Multilog2, the connectors used for communications are frequently shared; they also include the connections required for fitting an external battery (see section 2.2). Because of space limitations, the label may not indicate this (e.g., It may simply be labeled “COMMS”).
A typical connector used for communications and its matching communications cable is shown in Figure 3.

The connector of the communications cable will only include the pins required for communications purposes.
To use the communications cable, temporarily remove any existing connector, and re-connect it when finished. Alternatively, an adaptor (Y-cable) can be inserted to be able to support the logger using both functions together.
Attach the Comms cable to the logger, and then complete the connection to the IDT host using one of the methods described in section 2.8.
Examples of suitable programming cables are given below:

10-pin : COM AEUSB (USB to RS232 comms cable).
CABA2075 (direct USB comms cable).
6-pin : CABA8585 (direct USB comms cable).

COMPLETING THE COMMUNICATIONS PATH
For IDT to communicate with the logger, first select the appropriate cable and connect it to the COMMS connector of the logger, as described in section 2.7. The USB-A end of the programming cable should be used to connect to the IDT host by using one of the following methods:

IDT – USED WITH A PC (& WINDOWS).
Prior to use, the PC should have the IDT (PC version) programming tool installed.
The USB-A end should be plugged directly into a USB-A port of the PC (or to USB-B or USB-C port via a suitable adaptor). Refer to Figure 4.

IDT APP – USED WITH A TABLET (ANDROID) / USB OPTION
Certain Android-based Tablet devices (which must have an available USB port) are able to use this method. (For latest information about known compatible devices, contact your HWM representative).
Prior to use, the mobile device should have the IDT app software installed.
The USB-A end should be plugged directly into a USB-A port of the tablet (or to a USB-B or USB-C port via a suitable adaptor). Refer to Figure 5.

This connection method is only compatible with a 10-pin logger connector and using the COM AEUSEB (USB to RS232) comms cable, or CABA2080 (USB to RS232) Y-Cable.

IDT APP – USED WITH A MOBILE PHONE OR TABLET / BLUETOOTH OPTION
Certain mobile phone or tablet devices (which must be Android or iOS-based and support Bluetooth radio) are able to use this method. (For latest information about known compatible devices, contact your HWM representative).
Prior to use, the mobile device should have the IDT app software installed.

The connection path (refer to Figure 6) makes use of a communications adapter known as the HWM ‘Bluetooth Interface Link’. Connect the logger end of the communications cable to the logger. Then the USB-A end of the communications cable should be plugged into the USB-A port of the Bluetooth Interface Link unit. The device should be turned on during use. The IDT app is required to be paired to the Bluetooth Interface Link unit prior to communication with the logger. The Bluetooth Interface Link handles protocol translations and flow control of messages between the logger
(via the comms cable) and the radio link.

FA'AGAINA O LE LOGGER MA FESOOTA'IGA

The communications interface is always monitored for activity and the logger will usually respond, unless it is busy communicating to the cellular network.

GALUEGA FA'AGA LOGGER (MO LE FA'A'OGA MUAMUA)
Pe a lafo mai le falegaosimea, o le iunite o loʻo i totonu o le 'faiga faʻatau' (faʻateʻaina; e le saini pe valaʻau i totonu). O lenei faiga e talafeagai mo felauaiga poʻo le teuina umi. Ina ia faʻaaogaina le logger, e tatau ona faʻagaoioia muamua.
The process for doing this depends upon the logger setting for logging re-activation. Various setting options are available (specified time, upon connection of an external battery, upon the activation of a magnetic switch, ‘immediately’).
Most loggers are set to start ‘immediately’ upon having their settings read by IDT and then saved back to the unit.
Once activated, the logger will initially go into the state of ‘Waiting’ (for a short time). Then it will enter a status of ‘recording’, where it is executing its repetitive logging functions.
The method depends on which version of IDT is being used:

For IDT (PC), the user can do this manually (even if no program changes are required). (Refer to the IDT user-guide for the steps required to read the logger program and then to save it back to the unit using the ‘Setup Device’ button).

For the IDT app, the user can also do this manually via a Start Device’ button. In addition, the app will check for potential issues whenever the user makes a controlled disconnection of the logger from the app, including a check for a logger that is not yet activated / recording.

Before leaving site, check that the logger has been correctly set up for logging, call-in tasks and that it is in a state of ‘Recording’ (logging). Refer to the IDT user-guide for guidance on how to check these points.

Wired connections are made to the logger via a connector mounted through the logger case. Various sizes are available and can contain either pins or sockets. Some examples are shown in Figure 9 and Figure 8. A dust-cap is available as an option to keep unused connectors free of water and debris (see Figure 7).

Some connectors are single-purpose in nature (e.g., For connection of a single sensor). However, other connectors may be multi-purpose (e.g., Having both a connection for a programming cable and also for the supply of power from an additional battery).
Where a connector is multi-purpose, a Y-adapter cable may be required to split out the various functions.
For water pressure measurement, the electrical connection to the sensor may be made via a standard electrical connector. This interface is known as an “External Pressure” type. It allows a cabled pressure transducer (sensor) to be connected to the logger. HWM can provide a variety of cabled pressure sensors with the appropriate connector for the logger.

An alternative for water pressure measurement is for the transducer (sensor) to be built into the unit, as shown in Figure 10. This logger interface is known as an “Internal Pressure” type. It allows pressurized water to be connected to the logger directly, via the use of hoses fitted with a quick-release connector.

INSTALLING THE LOGGER
The logger must be mounted in a suitable location where the sensors to be attached can reach their intended installation points. Position loggers, sensors, and antenna away from sources of electrical interference such and motors or pumps. Cables and hoses should be routed without causing any hazards. Do not allow any equipment to rest on hoses, cables or connectors as crush damage can result.
The logger should be installed in the orientation shown in Figure 1 for optimum battery performance.

FA'ATAU IPU
The Multilog2 can be secured to a wall using a suitable bracket, an example of which is shown in Figure 11. Ensure the wall and fixings used are able to bear the weight of the logger and cables attached.
The bracket used may offer a potential mounting location for the antenna, although the installer should seek to find the optimal location for the antenna within the installation.

ELECTRICAL CONNECTIONS TO THE LOGGER
When making electrical connections to the logger (e.g., attaching a connector for a sensor), ensure the connector is correctly fitted. Both parts of the connector should be dry and free of debris. The connectors are keyed to ensure correct alignment of pins and receptacles. Align the sensor to the logger connector and push fully home. Then rotate the outer part of the sensor connector until it engages with the fastening mechanism and locks into place. The connector will then be secure and watertight.
When removing connections, follow the reverse steps of the procedure describe above. Always handle the connection by the connector; do not pull the cable as this could cause damage.
Route all cable so they do not cause any potential hazards and secure into place using suitable ties.
For antenna, follow the steps given in section 5.18.

Pressure sensors supplied by HWM normally measure pressure relative to atmospheric pressure. Since there can be some variation in local atmospheric pressure (e.g., due to altitude), the loggers have a facility to re-zero the pressure sensor.
E tatau ona faia lenei mea i le masini e faʻaalia i le ea o le ea.
Prior to connecting the transducer to the actual measuring point, leave it exposed to air. Then “re-zero” the sensor using the method found in the IDT user-guide.

SENSOR OMI (FAFO)
A pressure input may be presented as an electrical interface, using a 4-pin or 6-pin MIL-Spec connector (see Figure 9 on page 14).
Cabled pressure sensors for the Multilog2 are available from HWM. For most situations, sealed type pressure (or depth) sensors are used, and the sensor will be wired directly to the connector, as shown in Figure 13.

E fa'aaoga e le logger mo sina taimi le mana i le masini a'o le'i (ma le taimi) faia se fua.

FA'A'OGA FA'AVAE FA'ALU (METER PULSE COLLECTION)
Depending on the model supplied, the logger may have 0, to 6 Flow inputs. These are digital inputs, designed to sense the open or closed condition of a switch (activated by the installed meter). To use the flow channel(s) the logger must be set up (using IDT) to know what each meter pulse represents.

FA'AMATALAGA O AUALA LAVA MA FA'AALIGA FA'AALIGA
Flow of a fluid in a pipe is usually detected by a meter, which produces pulses related to the volume of fluid passing through it. There are several types of meters; some can detect both forward flow and reverse flow (bi-directional flow); some can detect flow in one direction only (uni-directional flow). There are therefore several ways of implementing the meter pulse output signals from a meter. Your logger must have the correct interface and settings for the signaling from the meter to be compatible with it.
The Multilog2 Flow inputs sometimes require two input signals in order to work with the meter-pulse signaling of certain meters. A pair of inputs can therefore sometimes be configured to operate as a single channel. Other meter types only require one signal, so the pair of inputs can operate as two separate channels.
The pair of Flow signals can be labeled in one of the following ways:

	Alternative signal names
Pair of FLOW faailoilo	Flow Input 1	tafe 1	Pusa	Flow (Forward)
Pair of FLOW faailoilo	Flow Input 2	tafe 2	Fa'atonuga	Flow (Reverse)
masani	GND

The labeling depends on the factory default for the configuration of the Flow channels on your logger model-number, but sometimes alternative types of configuration can be achieved by changing logger settings.
Afai o le logger ua muai faʻapipiʻiina e le fale gaosi oloa e naʻo le 1 Flow channel (datapoint stream), e mafai ona faʻaogaina le paʻu o mea i totonu o se tasi o auala eseese e tolu:

(1) Input 1 can be used with a Uni-directional meter (one which only measures forward flow / consumption).
For use in this configuration:
• Input 1 acts to collect meter pulses, and
input 2 is usually left disconnected (or allocated to use as a ‘Tamper Alarm’, or used as a Status input).
(2) Inputs 1 and 2 can be used as a pair with a Bi-directional meter (one which can measure both forward and also reverse flow).
For use in this configuration:
• Input 1 acts to collect meter pulses, and
• input 2 is used for the flow direction indication from the meter
(open = forward flow, closed = reverse flow).
(3) Inputs 1 and 2 can be used as a pair with a Bi-directional meter (one which can measure both forward and also reverse flow).
For use in this configuration:
• Input 1 acts to collect meter pulses (forward flow direction), and
• input 2 acts to collect meter pulses (reverse flow direction).

Where the logger is pre-configured by the factory to produce 2 Flow channels
(datapoint streams), the pair of inputs can be used as 2 independent uni-directional Flow input channels (channels 1 and 2).
Each input can be used with a Uni-directional meter (one which only measures forward flow / consumption).

E ala ile LOGGER 4-PIN BULKHEAD CONNECTOR
Multilog2 Flow signal inputs are presented on a 4-pin connector (see Figure 9 on page 14). Each connector has a pair of Flow signal inputs.

O le pine o lenei so'oga o lo'o fa'aalia i lalo:

	Logger bulkhead connector pinout : 4-pin Flow Inputs
Pin	A	B	C	D
Fa'ailoga	(le feso'ota'i)	Flow Input 1	Flow_GND	Flow Input 2

Check the meter to which the logger is going to be connected and ensure its meter pulse signaling method is understood, along with the significance of each meter pulse.
Connect the logger to the meter-pulse outputs of the meter using a suitable cable. If cables with bare tails have to be interconnected, refer to the guidance in section 5.5.
Use IDT to complete the setup, ensuring the logger is correctly set to interpret the meter pulses. If the logger is required to keep track of the meter counter display, take an initial reading of the meter counter and program it into the logger. The logger uploads additional consumption regularly, so a meter reading can be made remotely.

SO'O'I UIGA LE'I MATUA I METOGA
When using a cable that is unterminated, an installer will be required to make their own connection to the other equipment on site.
When making a connection to Multilog2 you will normally need to splice the bare tails together. It is important that a waterproof connector housing is used, such as the “Tuff-Splice” enclosure available from HWM.

Fa'aaliga: Long data connections should always be made using screened cable. The use of screened cable will ensure maximum rejection of interference from outside sources. Always use a common ground point without creating ground loops.

TULAGA INPUT
The Status Input pins are a re-purposed use of the Flow input electronics (see section 5.4). A change in the software driver for the connector gives the input pins a different functionality.
The interface will be labelled as ‘Status’ or ‘Dual Status’.
O le pine o lenei so'oga o lo'o fa'aalia i lalo:

	Logger bulkhead connector pinout : 4-pin Status Inputs
Pin	A	B	C	D
Fa'ailoga	(le feso'ota'i)	Status Input 1	Status_GND	Status Input 2

The Status Input signals can be configured for general-purpose use in detecting switch contacts. This has many uses.

Detection of door / window / equipment-access openings for security purposes.
A ‘spare’ pin on a flow channel can be used to generate a ‘tamper’ alarm in the event that the logger cable is cut or removed from the meter.
(The meter must support this facility by providing a closed loop from the tamper input to the return pin, Status_GND).

Connect the logger to the external equipment using a suitable cable. If cables with bare tails have to be interconnected, refer to the guidance in section 5.5.
Use IDT to complete the setup, ensuring the logger is set to generate the desired alarm.

OUTPUTS (DIGITAL SWITCH: OPEN/CLOSED)
Multilog2 Outputs are presented on a 3-pin connector (similar to Figure 8 on page 14). Up to four outputs can be supported. Each connector has a pair of outputs.
The interface will be labeled as ‘Dual Output’.

O le pine o lenei so'oga o lo'o fa'aalia i lalo:

	Logger bulkhead connector pinout : 3-pin Outputs
Pin	A	B	C
Fa'ailoga	Galuega Faatino 1	Galuega Faatino 2	GND

The logger does not supply any power to the output. The output takes the form of an electronic switch (transistor), which can either be open or closed. When closed, the current path or is between the output pin and ground.
Ole fua maualuga ole voltage is 12V (D.C.)
The maximum rated current is 120mA.
A common use of the Output pins is for pulse replication (of meter pulses that are input to the Flow channels). Where this is implemented:

Flow input 1 is replicated to Output 1
Flow input 2 is replicated to Output 2
Flow input 3 is replicated to Output 3
Flow input 4 is replicated to Output 4

The Output signals may also be used to activate external equipment.
In order to use the outputs, a suitable cable is required (the exact requirements will depend on the equipment the logger is being used with; discuss with your HWM representative). If cables with bare tails need to be interconnected, refer to the guidance in section 5.5.
Use IDT to complete the setup, depending on your application for the output.

MA'A I FAFO
The use of an external battery is optional for many installations but may be required to support the logger in order to obtain the required length of service.
For best battery life, orient the external battery in its preferred orientation (refer to the labelling on the battery). Batteries are heavy devices. When positioning the battery, check that it is not crushing any cables or tubes within the installation. Ensure the battery is secure in its installation position (so it cannot fall). Then connect it to the logger.
The logger connection for an external battery will be presented via a (6-pin or 10 pin) connector that is shared with the programming interface (labelled “COMMS”).
The cable that is used for interconnecting the external battery pack to the logger will only include the pins required for supply of power; pins assigned for communications purposes will not be fitted.
The external battery connection must be temporarily disconnected whenever a logger programming cable needs to be attached.

SONICSENS 3 (ULTRASOUND DISTANCE / DEPTH SENSOR)
Where a SonicSens3 interface is available on your logger, it will have a 6-pin connector, similar to that shown in Figure 8, on page 14.

The interface provides power and communications to the sensor, which measures distance to a fluid surface. By input of other parameters (e.g., distance from the bottom of the water channel) the logger can calculate water depth. It can also derive a variety of other measurements such as flow rates if situated near an open weir.
Va'ai ile SonicSens-3 user-guide (MAN-153-0001) mo fa'atonuga ile fa'apipi'i ma le setiina o le sensor mo le fa'agaioia.

Fa'aaliga: Multilog2 loggers are not of an intrinsically safe construction, and so cannot be used within an environment where a potentially explosive atmosphere may be present.

SONICSENS 2 (ULTRASOUND DISTANCE / DEPTH SENSOR)
Where a SonicSens2 interface is available on your logger, it will have a 4-pin connector, as shown in Figure 8, on page 14.
The interface provides communications to the sensor, which measures distance to a fluid surface. By input of other parameters (e.g., distance from the bottom of the water channel) the logger can calculate water depth. It can also derive a variety of other measurements such as flow rates if situated near an open weir.

TUSI FA'AVAE (RTD – PT100)
The logger may be constructed with a 4-pin connector (see Figure 9, on page14) for connection of a temperature sensor. Typically, this will be a PT100 RTD sensor. The logger interface will be labeled “TEMP” or similar).
The pinout of the connectors is shown below.

When ordered with a temperature sensor from HWM, the sensor will have the correct connector fitted for the Multilog2 logger. The logger input will also be factory calibrated for use with the supplied sensor.

LNS INPUT (LEAK-NOISE SENSOR / HYDROPHONE)
The logger may be constructed with a 4-pin connector (see Figure 9, on page14) for connection of a high sensitivity audio sensor, used for detecting the noise of a leak from a pressurized water pipe.
The interface will be labeled ‘LNS INPUT’ (or similar).
Typically, the sensor will be a Leak Noise Sensor from one of the HWM PR4LNS-1 family. The Multilog2 is also compatible with the Hydrophone-2 sensor (and its earlier version, Hydrophone). Both use the same connector. There are only minor differences in setup of the logger for their use. There are significant differences in their installation methods.

ANALOGUE CURRENT INPUT (4-20MA)
The logger may be constructed with a 4-pin connector (see Figure 8, on page 14) for connection of a sensor which employs an output current as a method of signalling.
Two interface types are available:

Pa'u.
Malosi.

4-20MA (PASSIVE)

A wide variety of sensors are available with this interface. However, not all have the same power requirements. The connector is able supply up to 50mA of current. The output voltage is variable (from 6.8 V to 24.2 V, in 32 steps), and is able to be set using IDT.
To avoid damage: Prior to connecting the sensor, use IDT to ensure the correct output voltage for the sensor is set.
The logger does not supply continuous power to the interface, but only activates it for a short time whilst making a measurement. IDT gives access to controls to set the amount of time the sensor has power applied prior to and during measurement. The installer can set these to allow for any initialisation or settling time the sensor requires.
When ordered from HWM, the sensor will have the correct connector fitted for the Multilog2 logger.

FA'AALIGA FA'AVAE (RS485 / MODBUS)
The logger may be constructed with a 4-pin connector (see Figure 8, on page 14) for connection of a sensor which employs the RS-485/MODBUS method of signalling; this is a serial data interface.

Fa'aaliga: Ensure the attached sensor has the RS485/MODBUS protocol selected, otherwise
communications will fail.

Pa'u.
Malosi.

Mo se atinaʻe Passive, e le tuʻuina atu e le logger le mana i le masini; e tatau ona i ai lona lava puna o le mana.
For an Active interface, the logger provides temporary power to the sensor, just before (and during) the measurement cycle.
The port type (active or passive) can be determined by inspection as to whether (or not) there is a voltage output control shown within IDT. In addition, the connector label will indicate ‘MODBUS’ or ‘POWERED MODBUS’.
A wide variety of sensors are available with this interface. When ordered from HWM, the sensor will have the correct connector fitted for the Multilog2 logger. In addition, the sensor type will have been tested with the logger to confirm compatibilty for use to obtain certain measurements. However, this may require selecting a specific driver for the sensor within IDT.

The Multilog2 operates as the master device when using the Modbus protocol. It sends setup instructions and other information to the attached sensor equipment (which operates in slave mode). The protocol includes the ability to address each register in order to read and (depending on the attached unit) write to the registers. Measurement results are made available to the logger by reading them from specific registers in the sensor equipment over the Modbus link.
O meafaigaluega fa'alogo o le ai ai se tuatusi e tatau ona fa'aoga e le logger e iloa ai pe a feso'ota'i. O le setiina o le logger e tatau ona aofia ai le tuatusi o le masini faʻapea foʻi ma faʻamatalaga avanoa mo le resitala (code code, tuatusi resitala amata).

The quantity of registers to be read will depend on the format of the data within the sensor registers. The logger can handle multiple formats of numeric data (e.g., 16-bit signed, 16-bit unsigned, float, double); however, the expected data format must be specified in the logger setup; this will ensure that the required number of registers are read and that the data is correctly interpreted by the logger. The read data can then be used to obtain the channel datapoints.
When setting the logger for use with your sensor, usually the “generic” settings are suitable. However, some modification of the logger operation is required for certain types of sensor equipment in order to get the best out of them. IDT provides a control to select specific sensors from a list. Once chosen, the logger will handle any peculiarities of the behavior of the sensor, its protocol, or additional needs for the measurement being taken (e.g., additional exchanges of information between the logger and the sensor equipment).

Refer to the IDT user-guide regarding how to set up the RS485 / Modbus interface. This must be read in conjunction with the user-guide of the equipment that is being attached; this will provide information on the measurements available from the sensor equipment registers (and the numeric format of the data), and how to initiate register reads to obtain the required data.
The installer should use IDT to confirm or adjust the settings of the logger that request the required measurement data from the sensor. Then use IDT to correctly scale and interpret the physical parameters the sensor is used to detect.

The installer should use IDT to confirm or adjust the settings of the logger to request the required measurement data from the sensor. Then use IDT to correctly scale and interpret the physical parameters the sensor is used to detect.

RS485 / MODBUS (ACTIVE)
The logger interface will be labeled “POWERED MODBUS” (or similar).

Fa'aaliga: When supplied with (and configured for) a known sensor, the logger MODBUS interface may alternatively be labeled so as to identify the sensor itself. Examples o:

For an ‘Active’ interface, the logger usually provides temporary power to the sensor, just before (and during) the measurement cycle. The sensor used must be compatible with the logger power supply to the interface (voltage and current output). It also has to be compatible with the timing of the power activation and any exchange of messages. Consult your HWM representative for advice on sensor compatibility or if you have any specific sensor requirements.
A wide variety of sensors are available with this interface. However, not all have the same power requirements.
To avoid damage, check the sensor is compatible with the logger power supply range and use IDT to check that the logger power settings have already been correctly set prior to connection.

The interface is able supply up to 50mA of current.
Le galuega faatino voltage can be set using IDT (from 6.8 V to 24.2 V, in 32 steps).

IDT gives access to controls to set the amount of time the sensor has power applied prior to and during measurement. The installer can set these to allow for any initialization or settling time the sensor requires.

ATENNA INPUT (GPS SATELITI)
The Multilog2 may have been fitted with an internal radio receiver which can receive signals from GPS satellite stations. These loggers will have an additional antenna connector fitted, which must be connected to a GPS antenna for correct operation.

Fa'aaliga: Do not confuse this with the antenna supplied for cellular communication, as they are not compatible with each other.
The GPS antenna can be identified by the “GPS” indication on its cable, as shown in Figure 19.

Secure antenna to the lid using a washer and the supplied nut.
If required, apply a resin epoxy such as Marine “Goop” to the perimeter of the antenna to help stabilize its position within the lid and to prevent water running onto the antenna cable. Do not cover the top of the antenna body as this may impair reception of satellite signals. Ensure all surfaces are clean and dry before applying the adhesive. Follow the adhesive manufacturer’s instructions.

APPENDIX 1: SYSTEMS AND FEATURES REQUIRING IDT (PC)

Historically, setup of Multilog2 loggers was undertaken using the IDT (PC/Windows) tool. Setup of most Multilog2 logger functions for Pressure and Flow channels and the most commonly used alarm types has recently been introduced to the IDT (mobile app) tool. However, the IDT (mobile app) does not yet support some situations.
The following logger types require IDT (PC) for their entire setup:

WL/*/*/* Multilog2 logger device (models for use in WITS systems). Refer to the IDT (PC) user-guide for most settings. Additional information for WL series models can be found in the following user-guide: MAN-147-0017 (Supplement for models supporting WITS protocol).
RDL6*LF/* Multilog (original) logger devices.

The following logger/sensor combinations require IDT (PC) for setup:

Multilog2 using a SonicSens2 sensor.
Multilog2 using a SonicSens3 sensor.
Multilog2 using a RS485/MODBUS sensor.
Multilog2 using an SDI-12 sensor.
Multilog2 using a Hydrophone or LNS (Leak-Noise Sensor).
Multilog2 using a GPS Satellite (for either location or Time-sync).

The following logger features require IDT (PC) for setup:

Update of firmware of logger or attached sensors.
Fast logging features (Pressure Transient, Enhanced Network logging).
Flow Rate (when calculated from flow velocity, channel depth, channel geometry).
Profile Alalaga.
Tamper Alalaga.
GPS functions, including GeoFence Alarm.

APPENDIX 2: COMMUNICATING TO LOGGER VIA SMS

Fa'aaliga: This facility may not be available on your logger, depending on the SIM card fitted. Some SIM cards or networks or service providers do not have SMS messaging available. (See also section 1.4).

Applying a ‘Modem Activation Key’ (See Figure 25) to the 10-pin Comms interface for a period of 10 seconds will activate the logger’s cellular communications modem for a period of 5 minutes. This will allow an installer to send SMS (text) messages from a mobile phone and for the logger to respond.
(There is an alternative way to do this using IDT).
Tapuni le potu po'o le kapeneta ina ia i ai mea uma i lona tulaga mulimuli.
Using a standard mobile phone, send a text message to the SMS number of the logger (check the logger label), including the international dialing code if needed.

E tatau ona faitau le feau tusitusia TTTT#

A maeʻa ni nai sekone / minute (faʻalagolago i le fesoʻotaʻiga fesoʻotaʻiga) o le a toe tuʻuina atu e le logger se feʻau ia te oe ma faʻamatalaga o lona tulaga o iai nei.

Example tali mai se logger:
TTTT138-002 V01.70CSQ:1010.9VyouridRT hh:mm ss dd-mm-yy …

Ina ia fa'amalamalama le fe'au na toe fa'afo'i mai, fa'amolemole va'ai le laulau o lo'o i lalo:

Savali	Fa'amatalaga
TTTT	Original command text without #
138-002	Logger type number
V01.00	Firmware version in Logger.
CSQ: nn	Signal strength nn (nn = 6 to 30)
10.9V	Faʻagaioiga voltage
yourid	Your Logger ID
RT hh:mm ss dd-mm-yy	Real Time Clock setting
ST hh:mm ss dd-mm-yy	First Time the logger was started
LR hh:mm ss dd-mm-yy	Last Time the logger was re-started
Ch1 (A) 0029.0	Channel 1 29.0 units
Ch2 (A) 0002.2	Channel 2 2.2 pulses/sec

If the CSQ: value in the message is OK, then the installation is complete. The logger will automatically go back to sleep after 10 minutes.

E mafai ona tuai i le fesoʻotaʻiga SMS, o le tali atu i lau feʻau atonu e le vave. Afai e leai sau tali i le 10 minute, toe tatala le potu ma faʻaaoga le modem diagnostic lafo oe lava SMS suʻega. Afai e o'o mai lenei mea, ona fa'aleleia lea o le nofoaga o le antenna ma toe taumafai.

Fa'aaliga: Some Roaming SIM cards do not accept incoming text messages.

Check with your service provider if you are unsure.
