Indicators:
Power – This LED (on) indicates that DC power supply is applied to the Reciter
Ethernet – This LED (on) indicates that the transceiver is operating in Digital mode
Analog – This LED (on) indicates that the transceiver is operating in Analog mode, - if the
transceiver is operating in dual mode, both Digital and Analog LED will be on
Tx – This LED (on) indicates the transceiver’s transmitting path is active
Rx – This LED (on) indicates the transceiver’s receiving path is active
Alarm – This LED (flash) indicates the transceiver is in alarm state, press the status button
to listen the alarm information
Connectors:
