This happened to me on a gig last week, and it is classic DMX fault symptom that was the kick-start of this DMX problem guide. Some of them are fine, some don’t respond to DMX control at all and one just seems to think it is a random search light. But, your moving lights start to act strangely.


Ok, so you’ve got the lighting rig together, dimmers working, moving lights responding and you need to start programming the desk because you have to be ready in a few hours for rehearsal. If you really way to become a DMX systems ninja, runs a course on DMX Stage Lighting Systems online. If you do have a fault in your DMX chain, it can be tricky to find the source so On Stage Lighting has this guide to troubleshooting DMX, how to spot a DMX fault and how to trace and solve the problems – and without a DMX tester.

A DMX control system is pretty simple and robust and DMX faults are a less common problem in stage lighting, compared to blown lamps etc. DMX512 is the most common stage lighting control system that can control both intelligent lighting and DMX dimmer systems.
