Long ago I downloaded all the Lionel supplements so I'd have them locally. However, I didn't find the wiring diagram for this particular unit.
George, what do you use pin 2 on the CC-M for? I've never found a use for it, and when I did connect it to the RS Commander, I didn't get command control of the sounds. I figured if it was buffered, that would be a solution instead of a transistor buffer, but it was no-go. I can honestly say in 100+ installations, I've never used that serial output.
I've always meant to 'scope the two pins to see what actually comes out of that pin, and how it differs from the serial input. It's just never risen to the top of the queue.
