3 Operation
3.1 Physical
Setup
Each unit installed in the field requires the following for operation:
Power
- Connect power (+6-30 VDC for 900 MHz units) to the connector (Phoenix P/N:
1786831). Be sure to use a regulated, clean power source, and confirm the power source is
capable of delivering enough current (at least 500ma) to run the unit.
RF Data Transceiver Antenna
– Connect an appropriate antenna cable and antenna. The
connector on the Navigator IIm is an
SMA-type female
. The antenna cable length should be
as short as possible to avoid power loss. Be sure to use tested, high quality, low-loss antenna
cables in good condition. Poor cables and connectors can be difficult to troubleshoot.
GPS Receiver Connection
– If utilizing an internal GPS receiver, connect a GPS antenna
cable and antenna. The connector on the Navigator IIm is a
TNC female
. The antenna cable
length should be as short as possible to avoid power loss. Be sure to use tested, high quality,
low-loss antenna cable in good condition. Poor cables can be difficult to troubleshoot. The
GPS antenna connector is biased with +3.3VDC for active GPS antennas.
Note that placing the GPS antenna near some other antenna with high power RF radiation
may affect the GPS receiver’s ability to correctly produce position data.
