Table 1.3 – Status LED operation modes
Installing your Syncbox
The Syncbox is housed in a robust aluminium enclosure. The unit is supplied complete with an active patch GPS antenna (or anti-jam antenna option), a power adapter and associated cables.
Please install your Syncbox following the notes below. To configure your Syncbox, please refer to sections 3 (Syncbox Control software), 4 (The Ethernet port) and 5 (RS-232/RS-485 output).
Physical installation
The Syncbox should be placed on a flat surface. Alternatively, the Syncbox can be secured to any surface using the supplied removable brackets.
Connecting and installing the GPS antenna
As standard, your Syncbox is supplied with a GPS patch antenna. We also offer a range of antenna, lightning arrester and cable upgrades to provide improved GPS decoding performance.
If you have not ordered an antenna upgrade, please refer to section 2.2.1 for installation details relating to the standard GPS patch antenna.
If you have ordered an optional antenna upgrade, please refer to section 2.2.2
If you have ordered a lightning arrester, please refer to section 2.2.3.
Installing the standard GPS patch antenna
For your Syncbox to operate reliably, the GPS antenna needs to have at least a partial view of the sky (increasing the amount of sky visible will provide correspondingly better performance).
The antenna should be mounted either externally (in a protected position) or in an internal position with a view of the sky (for example, on a window ledge). If you choose to mount your antenna internally, best operation will be achieved by choosing a window facing towards the equator (ensure the window is not coated with a metallised film as this may disrupt the GPS signals).
Once installation is complete, you may choose to secure the GPS patch antenna in position using the adhesive tape supplied.
Connect the GPS patch antenna cable to the ‘GPS ANTENNA’ connection on the rear of the Syncbox.
Installing the optional anti-jam GPS timing antenna
- The optional anti-jam GPS timing antenna should be installed externally, with the maximum possible sky visibility. For most installations, the ideal location will be the roof of your building. The antenna has been designed to withstand extreme temperatures, rain, snow and sunlight.
Ideally, the antenna should have a clear uninterrupted 360 deg view of the horizon. For installations where an unobstructed view of the sky is not practical, the antenna should be installed with as large a view as possible of the sky towards the equator. Installing the antenna with a substantially reduced view of the sky will degrade system performance and may increase synchronisation time. - The antenna should be mounted with the top of the dome facing directly upwards and secured using the antenna bracket. Care should be taken to ensure the fixings used (not supplied) as suitable for the application.
- The antenna should be connected to the lightning arrester using the appropriate length TNC/TNC coaxial cable (available separately). For installations where a lightning arrester is not used, the antenna should be connected directly to the Syncbox using the appropriate length TNC/SMA coaxial cable (available separately).
- WARNING: WHEN INSTALLING THE ANTENNA WITHOUT A LIGHTNING ARRESTER, THE ANTENNA MUST NOT BE INSTALLED IN A POSITION WHERE IT MAY BE SUBJECTED TO A DIRECT LIGHTNING STRIKE.
TO PREVENT MOISTURE PENETRATING THE RF CONNECTION, THE COAXIAL CABLE CONNECTION TO THE ANTENNA SHOULD BE SEALED USING THE SUPPLIED SELF-AMALGAMATING TAPE. THE TAPE SHOULD FULLY COVER THE COAX HEAT SHRINK AND THE - TNC CONNECTOR, AND SHOULD FINISH ON THE ANTENNA MOUNTING THREAD. THE TAPE SHOULD BE SUPPLIED IN SUCCESSIVE HALF-LAPPED LAYERS WORKING UP TOWARDS THE ANTENNA. TO ENSURE GOOD SEALING OF THE RF CONNECTION, THE TAPE SHOULD BE GENTLY STRETCHED AS APPLIED.
Installing the optional lightning arrester
The optional lightning arrester provides surge protection for your Syncbox. It should be connected inline between the external antenna and the Syncbox. The lightning arrester should be installed internally as the point where the antenna cable enters the building.
The lightning arrester is supplied with a separate instruction sheet with full installation instructions. Please consult this separate instruction sheet when installing your lightning arrester.
PLEASE NOTE: THE LIGHTNING ARRESTER MUST NOT BE INSTALLED EXTERNALLY.
IT IS IMPORTANT THAT THE LIGHTNING ARRESTER IS GROUNDED TO A LOW IMPEDANCE GROUND SYSTEM FOR PROPER OPERATION.
Power connection
The Syncbox is supplied with an external power adapter. The power adapter should be connected to the Syncbox before being connected to a local mains power supply.
USB setup port
Please note: The USB drivers should be installed before connecting the Syncbox to your PC.
The USB setup port should be connected to a Windows PC running the Syncbox Control software. Note that you only need to connect the USB cable if you wish to check or change any settings.
Ethernet port (version dependent)
Please note: In order to prevent possible network setup conflicts, it is recommended that the Syncbox is not connected to the network before the Ethernet port has been configured – see section 4.
The Syncbox should be connected to an Ethernet switch on a TCP/IP network. The Syncbox has a 10BASE-T/100BASE-TX auto-sensing Ethernet port and should be connected to the network using the supplied CAT5 patch cable (or similar).
RS-232/RS-485 output (version dependent)
The RS-232/RS-485 output provides user-programmable serial time and date messages and PPS (pulse per second) data. Please refer to section 5 (RS-232/RS-485 output) for connection and setup details.
Syncbox Control software
Please note: The USB drivers should be installed before connecting the Syncbox to your PC.
Syncbox Control is a Windows software application that acts as the control panel for your Syncbox. To change any setting on your Syncbox, connect it to your PC using the USB connection and open the Syncbox Control software.
The Syncbox Control software is available for download from the World Time Solutions web site: http://www.worldtimesolutions.com

- Once the software installation is complete, click the ‘Exit’ button.
What is the self survey?
The Syncbox GPS Time Server is designed to provide highly accurate time data. In order to achieve this, the Syncbox needs to calculate its position precisely.
The first time you power up your Syncbox it will perform an automatic self survey (the survey takes 35 minutes to complete and requires the Syncbox to be locked to the GPS satellites). When the survey is completed, the Syncbox switches to a time only GPS mode (where the location is assumed not to change), significantly improving the timing accuracy.
Once the survey is complete, the location is stored in the Syncbox. This ensures accurate timing, even if the Syncbox is rebooted.
If you relocate the GPS antenna by a significant distance, the Syncbox will detect this and automatically perform another self survey.
Alternatively you can manually trigger this by clicking the ‘Restart self survey’ button (see fig 3.3).
Using the Syncbox Control software
The main window of the Syncbox Control software uses a tab menu system. Tabs are provided for the setup of each output (Ethernet and Serial – please refer to sections 4 and 5 respectively), advanced settings and a general status tab.
The General Status tab (shown in fig 3.2 below) shows the UTC time and date, and the GPS synchronisation status.
The Advanced Settings tab (shown in fig 3.3 below) indicates the current software version in your Syncbox. There are also buttons to restore your Syncbox to its factory settings and to erase the stored location and restart the self survey. 
The Ethernet port
Note: The Ethernet port is only available on Ethernet versions.
The Ethernet port enables synchronisation of NTP/SNTP clients over a network. With sub 30 μsec timestamp accuracies and high bandwidth (5000 NTP requests per second) operation, the Syncbox is the ideal network timing solution for a wide range of applications.
Programming the Ethernet port
All settings related to the Ethernet port are configured using the Syncbox Control software (refer to section 3 for further details). Figure 4.1 below shows the Ethernet configuration screen. 
What is NTP?
Network Time Protocol (NTP) enables the synchronisation of computer clocks across data networks. It was originally proposed in the early 1980s and has been continually updated and used ever since.
Further information may be found at the home of the NTP project: http://www.ntp.org
The Syncbox Control software initially shows the currently programmed Ethernet settings. If you make a change to any of the Ethernet settings, the ‘Apply’ and ‘Cancel’ buttons will be enabled. Clicking the ‘Apply’ button will reconfigure your Syncbox with the new settings. If you don’t wish to apply your new setting, click the ‘Cancel’ button.
DHCP operation
The network interface can operate with DHCP (Dynamic Host Configuration Protocol) enabled or disabled. When DHCP operation is enabled, the Syncbox attempts to obtain network address settings automatically from a DHCP server on the network. With DHCP disabled, network address settings are manually entered into the unit.
If you configure the DHCP setting to ‘Obtain IP setting automatically’ (DHCP enabled) and the Syncbox has obtained its network settings, the new settings will be displayed in the IP address, Subnet mask and Gateway text boxes.
What is DHCP?
Dynamic Host Configuration Protocol (DHCP) enables the automatic assignment of IP address settings on a TCP/IP network.
Upon connection to a TCP/IP network, a client device configured for DHCP operation communicates with the DHCP server and obtains an IP address lease.
The DHCP protocol is defined in RFC 2131, available for download from: http://www.rfc-editor.org
If you configure the DHCP setting to ‘Use the following static IP settings’ (DHCP disabled), the Syncbox uses the IP address, Subnet mask and Gateway as programmed in the Internet Protocol configuration window.
NTP Broadcast
In a typical computer network, NTP operates in Unicast mode: an NTP client requests the time and the Syncbox responds directly to this request. However, in certain applications, it may be desirable to configure the Syncbox to operate in broadcast mode.
When operating in NTP broadcast mode, as well as responding directly to Unicast NTP requests, the Syncbox additionally broadcasts NTP messages to all devices on the local Subnet. Broadcast messages are transmitted every 64 seconds.
RS-232/RS-485 output
Note: The RS-232/RS-485 output is only available on serial versions.
The RS-232/RS-485 serial output provides time and date information at both RS-232 and RS-485 signal levels. The data format can be chosen by the user from a list of more than 25 different formats. The serial port also outputs high accuracy PPS (pulse per second) data at RS-232 signal levels.
Connecting to the RS-232/RS-485 output
The Syncbox has a female DB-9 (DE-9) D-Sub (DTE) connector. Table 5.1 shows the pin connections.
| Pin | Signal | Source | Description |
| 1 | PPS | Output | RS-232 Pulse Per Second |
| 2 | TXD | Output | RS-232 Transmitted data |
| 3 | RXD | Input | RS-232 Received data |
| 5 | GND | – | Signal ground |
| 8 | A | Output | RS-485 data A (non-inverting) |
| 9 | B | Output | RS-485 data B (inverting) |
| 4, 6, 7 | unused | – | – |
Programming the RS-232/RS-485 output
The RS-232/RS-485 serial data outputs and the PPS output are configured using the Syncbox Control software (refer to section 3 for further details). Figure 5.1 below shows the Serial Port configuration screen.
What is UTC?
In the early 1970s, with the increase in timing accuracy made available by modern atomic clocks, Coordinated Universal Time (UTC) replaced Greenwich Mean Time (GMT) as the world’s time scale.
Historically, GMT calculated the length of a day based on solar time patterns. UTC uses highly accurate atomic clocks as a calculation base.
The Syncbox Control software initially shows the currently programmed settings. If you make a change to any of the Serial Port settings, the ‘Apply’ and ‘Cancel’ buttons will be enabled. Clicking the ‘Apply’ button will reconfigure your Syncbox with the new settings. If you don’t wish to apply your new setting, click the ‘Cancel’ button.
- Serial data message format and repetition rate
Serial data is transmitted in one of more than 25 message formats. Available message formats are listed in appendix B.
The baud rate, data bits, parity and stop bits should be configured as required for your application.
RS-232/RS-485 data messages are transmitted aligned with the second edge. The Syncbox can be user-programmed to output a data string every second, or periodically (see Repetition Rate option in fig 5.1).
When set to the ‘on demand’ repetition rate, the Syncbox will only output serial data on receipt of a valid transmission request character on the RS-232 RXD pin. Valid characters are ‘s’ (0x73), ‘S’ (0x53), ‘t’ (0x74), ‘T’ (0x54) and ‘?’ (0x3f). The data transmission starts on the second edge after a valid request character has been received. - Reference time zone
The RS-232 and RS-485 data messages can be output referenced to any of the preprogrammed time zones. Appendix C lists the preprogrammed time zones along with offsets from UTC.
Where applicable, the preprogrammed time zones incorporate seasonal time change information, allowing changes to occur automatically. - PPS (pulse per second) output
The PPS (pulse per second) pin provides a high accuracy pulse every second, aligned with the second edge. The pulse is transmitted at RS-232 signal levels from pin 1 of the serial port.
The PPS pin is normally at a negative voltage level (RS-232 logic state 1). At the start of the second edge, the pin switches to a positive voltage level (RS-232 logic state 0). After the PPS pulse has ended, the pin switches back to a negative voltage level.
The width of the PPS pulse may be adjusted from 20 msec to 200 msec.
