So just to confirm, the actual cause for the controls not working is still unknown to the reader but the reason the measurements didn't make sense was swapped labels?

The controls weren't working because we had wired them up according to the labels which were wrong (which is also why the measurements didn't make sense to us).

Ah. A lesson from somebody who's built hardware that I'm sure you've now learned: make sure connectors can't plug into eachother unless they're supposed to. Even if they're different connectors, different keying, whatever, sometimes they can still be forced together.

I've seen datacenter techs successfully force an SFP optic in an RJ45 port. So yeah, the shape needs to be very different.
