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
