RF ENABLE SWITCH
This signal is the logic control input that designates whether the unit is in transmit or standby mode. If the
switch is in the ‘OFF’ position, the unit will default to
standby
mode.
Moving the switch to ‘RF Enable’
places the unit in
transmit
mode.

TEMP FAULT LED INDICATOR
The Temp Fault LED is an indicator of an over-temperature condition in the NuPower 11B02A-TAC. A non-
illuminated LED indicates normal operation, while an illuminated LED indicates an over-temperature fault
condition. The NuPower 11B02A-TAC incorporates internal logic circuitry that turns off the DC bias to the
RF amplifiers to naturally allow the module to cool off. Default thermal shutdown point is +85°C and will
restore bias and be fully functional when unit cools to approximately 70°C.
