Using RX antenna port on your TRX. [Example|https://remoteqth.com/img/ZAW-WIKI/k9-bidir-controller/cable_connecting_ext_trx.png] ** 2. Using TX ANT port on your TRX and switch antennas in the controller.

(also in Splitter) ** At the input of the controller. ** Input and output of the internal PCB board with BPFs and preamp. ** Output to TRX. When you forget to connect PTT and transmit into RX way. The protections should do its job with the power up to 150 - 200W. !Connectors * There are two ACC connectors ** RJ45 and SUB-D ** First 8 wires are the same.

Apply + 12V to preamp PIN, BPFs, to RX way PIN is the same as front panel switching, but you can use it for remote control.
