    Essentially it is a 1 wire connection.  How far did you get?

    Well, 2 if you count the Coax.  :)

    Connect the Relay out of the amp to the amp keying line on the 6300 with an RCA cable.

    Use a shielded audio type cable with standard male phono (RCA) connectors to connect the RLYjack of the ALS-500M to the transceiver or transmitter normally open amplifier relay terminal. 

    This connection has 12 volts open circuit and supplies less than 100 mA of current when pulled to ground.

    That is exactly how I connected the 6300 to the AMP.  
    6300 Phono connection TX to AMP Phono connection RLY.
    6300 will Not Key the AMP.
    To make sure the Cable is ok, I unpluged the 6300 end and sorted it and that keyed the AMP.
    Just an't figure out the problem???

    Dear Bill - with the latest software I have to enable the TX port that you are using on the radio each time.
