mast, or other suitable mounting platform.
I. The Antenna is designed to withstand rain, snow, and dust. When selecting the mounting
location for the antenna try to find a location that will not become buried in snow and/or
covered by foliage. Keep the top surface of the antenna clean and brush off any ice and
snow, to ensure your antenna performs optimally. In addition, ensure the connector
remains clean and dry.
2.3.2 Setting the Antenna Voltage
The ATS-6501 is capable of providing antenna power (0, 5, 12VDC) by DC biasing the
antenna cable but this can cause damage to an antenna if the wrong voltage is applied. Prior to
connecting an antenna to the unit, ensure the antenna voltage is set properly. The ATS-6501 is
shipped from the factory with the default antenna voltage of 0 volts. If this is not the desired
configuration then follow the steps below to set the proper antenna voltage.
A. Telnet into the system command port telnet ip addr 1700 or via the USB Port and the
ATS-6501> prompt should appear.
B. At the ATS-6501> prompt, type settings gps and press enter, this will display the user
configurable GPS settings for the unit to see verify the current voltage being supplied to
the antenna
