Connecting the GPS Antenna
Warning: Use an antenna rated for 12 Volts. Antennas not rated for 12 V will be
damaged.
The GPS antenna cable has a TNC connector at one end, and a BNC connector at the other
end. Run and connect this cable between the TNC connector on the GPSantenna , and the
BNC connector marked "ANT" on the rear panel of the XL-GPS instrument.
Making Additional Connections
Make the following optional connections:
• Connect the network port, NET, to the LAN using with the Cat-5 network cable
(supplied). This connection can be used to manage the XL-GPS remotely by
network, or optionally, for NTP.
• Connect RS-232 null modem cable (supplied) from SERIAL I/O to the serial port on
a PC. This connection can be used to manage the XL-GPS locally, using the
command line interface.
• Make any other connections needed to J1, J2, J3, and the Expansion Module.
Consult the XL-GPS User Guide as needed.
Connecting the Power Supply
Connect the Power Supply it to a power source. The green STATUS light indicates that the
XL-GPS is receiving power.
Upon receiving power, the XL-GPS goes through its startup sequence; displaying “Booting”,
Loading”, and “Starting”. After approximately 40 seconds, the XL-GPS displays the clock
status, and user interfaces (front panel/command line) become available.
For more information, see both the Grounding, and Connecting the Power Supply sections
in the XL-GPS User Guide.
Configuring Network Settings
The following additional steps are required to make the XL-GPS operational on a network.
Make the XL-GPS operational on a network if you plan on:
• Managing the XL-GPS remotely over the network.
• Distributing timing information from the XL-GPS over the network.
