When using an external antenna, placement of that antenna is critical to a solid data link. Other
antennas in close proximity are a potential source of interference; use the Radio Statistics or
Diagnostics software to help identify potential problems. It is also possible that slight adjustments
in antenna placement (as little as 2 feet) will solve noise problems. In extreme cases, such as
when the transceiver is located close to Pager or Cellular Telephone transmission towers,
FreeWave offers a band pass filter to reduce the out of band noise.
C. Diagnostic ports:
The FGRplusRE does not use the diagnostic port.
The radio cannot be programmed through
the diagnostic cable.
D. Power Connection
The FGRplusRE transceivers can be operated from any Class 2 power source, input voltages of
6V to 30V. The power source should be capable of providing at least 550 milliamps of continuous
current at 12V DC.
Transceiver is designed to operate in negative ground systems only.
