our ezpath blew a bdmc3 rev a 31944009 board. the replacement came in as a rev c 31944357C. The unit boots but fails on a switch open. the tech indicated it is for a door open. the tech is gone on vacation and there is no one to get the unit up. the rev C has a terminal block with three sets of pins I assume (no documentation available) check switch state. Can I jumper one or all of them and get the thing running as there are no door switches on the unit, it's pretty old.
