I'm trying to get clear on how COM1 is wired, so I can add the next control feature to my set of Remoterig boxes which I'm hoping to be control of a Elecraft KPA500 amp with their utility program.
I think I understand the radio side box is wired so the cable to connect to a device should be:
pin2 ---> pin3
pin3 ---> pin2
pin5 ---> pin5
Yes?
So is COM1 on the control side box wired also like above or straight thru like COM2?
Thanks,
