Hi all I am trying to connect my PC with Echolink to my TMV71a to transmit to our club's repeater. I bought the connection kit from Kenwood which has two cables. Each cable has a mini DIN connector at one end. One cable has a DB9 serial connector and the other has two 3.5mm audio connectors. On the back of the TMV71a there are two mini DIN ports. One is labeled DATA and the other is labeled PC. How do I know which cable plugs into which port? I have only found a very small amount of info on the web to help. Any info would be greatly appreciated.
