The sidecars are really finicky, aren't they? We blew out one of our DIO ports yesterday for no good reason at all. We had a standard limit switch connected between Negative and Signal. It returned a false at all times and caused a lot of panicking right before our unveiling. Luckily, we tried the port right next to it (DIO9) and reconfigured the programming for DIO9, and it now works . We're thinking of just taking out the programming for the limit switch altogether as it's not really needed.

So it wasn't electrical, and it wasn't programming.
