Oops, I thought the G1 and G2 forums were separate.
Thank you, Brendan.? I have no idea what version of Gemini I is, but I'll look the next time I'm at my observatory.? I have the stuff to clean my contacts on the way.? Hopefully it is that simple.? I also have a known "good" cable, so I can try swapping cables as well (I didn't think of doing that until I was on my way home Sunday morning).? If neither of those tests work out I guess I will have narrowed the culprit down to the controller itself.? Fingers crossed that isn't the case.
