PIN 4 —---------—>NC;
* RF Connector: SMA-50KFD
* RS485 PORT:
1) PA setup function: Module address(default=0), PA=ON/OFF, ALC, ATT;
2) PA Query function: Working status(on/off, Revers power, forward power Temperature, VSWR,ALC, ATT,）, Alarm(over Temperature, over power, VSWR, PA Fault);
3) Over Temperature Alarm：Alarm threshold +85℃, meanwhile switch off PA, When Temperature lower to +65℃, switch on PA automatically.
4) Over power alarm: when output power >Po+2dB
5) Amplifier temperature detection: Temperature detection rang including but not limited 0℃~+85℃, Detection accuracy<±3℃;
6) PA Fault Alarm: Low gain Alarm;
7) PA Forward Power detection: Detect total power, Modulated signal test, detection rang >20dBm, Detection accuracy<±2dBm;
