DMX pass thru

[DavidNorth]

@DavidNorth, is that what you were saying? And, is this something we can fix ourselves if that is the issue by placing a patch cable between the two lines and testing the third?

Yes, that's it exactly. If you jumper across the plate, the last plate should work. It is something you can fix by taking the plate out of the strip [4 screws] and swapping the wires from input to output and then it is taken care of forever. But do the jumper first just to be sure.

Bill asks an important question [has it ever worked?] for two reasons: if this is truly a new issue, then something really odd has happened and we need to dig further, and then, if it has never worked, then someone never checked it at turn on. That would fall on our shoulders now for resolution.

Let me know,

David

@DavidNorth , you got it correct. We didn't have a jumper cable at the theatre, but we tried swapping the wires to the other side of the path thru on electric #4. Worked like a charm, the wires must have been swapped backwards at install and we didn't have any DMX fixtures at install to check it with at that point. Bought our first set with a bit of funding about a year ago. Thanks for all your help everybody!
