Here's where I'm at.

I've got a BP4 board, and 675DK13 software. It cranks up, takes parameters etc, but doesn't seem to want to talk to the door board and selector properly. Once in a while it'll get selector status, but won't give me SUP to do a learn run. The door board won't learn either.

Selector and door board software incompatible?

Door Board 675AB1 675AB2

Selector 675A01

Original CLC software was 675AA1
