10. Hardware Description – T3-301
The T3-301 is a Friendcom FC-301/D 5-watt data radio module with a Tracker3
series board installed. The tracker takes over the module’s 9-pin D-sub
connector – its pin assignments are not the same as the as the bare FC-301/D
radio, and the Friendcom programming software and cable should not be used
with the T3-301. Configuration of the radio’s frequency and power settings is
accomplished through the tracker’s command line interface.
A serial and power breakout cable is available that provides power leads and a
D-sub connector matching the OT3m’s pin assignments, allowing the same
cables to be used. Alternatively, you can wire your own cable harness for direct
connection to the module.
A USB mini-B receptacle at the opposite end of the unit can be used to connect it
to a PC. The tracker may be configured when powered only by the USB
connection, but the radio will not function and frequency and power setting
commands will not be retained if 12v power is not provided to the module.
