OT2 to ICOM F521
- need a little bit of help to make a cable that will go from
OT2 to ICOM F521.
The ICOM F521 has two methods of input for data RJ45 Microphone jack or a acceesory cable OPC-617. For this thread I'm looking for the OPC-617 one.
From http://www.prestonmoore.com/repeater.html, I got the pin outs for the OPC-617. What confuses me in the PTT.
Here's what I think I should be making
OPC-617 DB-9M-------OT2 DB-9
Pin 3 Det. AF output-----RXA Pin5
Pin 4 Mod input----------TXA Pin1
Pin 5 PTT----------------PTT Pin 7?
Pin 8 Det. AF ground---- GRD Pin6
