CAT Cable "Pin Outs" (By Earl K6SE)

There are only three wires needed between the radio's CAT jack and the computer's serial port:

For a DB9 connector on the computer end:

Pin 3 to pin 3 = Data from computer to radio

Pin 2 to pin 2 = Data from radio to computer

Pin 5 to pin 5 = Ground

For a DB25 connector on the computer end:

Radio pin 3 to computer pin 2 = Data from computer to radio

Radio pin 2 to computer pin 3 = Data from radio to computer

Radio pin 5 to computer pin 7 = Ground

Check to see if the connection from either pin 3 or from pin 2 of the radio end of the cable to the appropriate pin on the computer end of the cable is open. Earl, K6SE
