Hello. Working on a Tac 20. Selector Shut down top terminal landing on error code 1025. BP parity error .. invalid BP input combination First time I have seen this error. Any info on it Would be great. Thank you. Last edited by Tech9; .

I know BP sensors are on selector board. But I just replaced those boards a few months ago and flipped selector shoes to tighten it up on tape .

Do I need lon cable and lon talk card ? I have cable but no adapter card
