More photos would be infinitely helpful. From the looks of what you posted already, it would seem that there should be some
DMX output nodes located around the
theatre. If not nodes then at least
cat5 (
ethernet) drops that run back to that panel in the booth. As each of the ports is labeled with a position, I would suggest checking each position for the other end of those lines. If there is not actually a
node there, then hopefully there is a box with an RJ-45 (
ethernet)
jack.
Your dimmers and the MAC500s get their data via
DMX. From your second photo it appears that you have at least one
DMX run from the
console (grey cable with the XLR-5
connector). You should determine where the other end of that cable is. Odds are it goes to your dimmers, possibly by way of in-wall wiring with wall mounted jacks. It is possible that before it gets to the dimmers it goes through a splitter. If this is the case, you might have a
line from the splitter to the dimmers and one to the moving lights.
We can be of lots of help if you can walk us through the
layout of the control cables. Take lots of photos.
If you want to really test your MAC500s, you should take them down and connect them directly to the
console via
DMX. This will eliminate any funkiness that may be in the
line and chain of equipment between the
console and the lights. This will let you know if the problems lie with the fixtures or the data path. If you need help addressing and patching the fixtures, let us know.
