Control/Dimming LED Light DMX Problem?

sounds like they are set in a sound active mode. double check your settings. also out of curiosity what happens if you unplug dmx @ your console, does the same thing happen? email me at [email protected]

... 3) Going way off the deep end. In theory you could get some DMX to RJ45 adapters, dump all your DMX cable and run CAT5 everywhere instead. Instead of a splitter run it through a router. That said, I've never done this to that extreme. I setup a small system this way and it worked great, but that was just a cat5 and DMX adapter daisy chain from the console through four wall mounted dimmer packs. I'm not sure about the router part of it, I would want confirmation from some of the geniuses around here first, but in theory I think it will work.

This will not work, in theory or practice. Further, I suspect you mean a hub or switch. DMX512 cannot be distributed with standard networking equipment. See the thread http://www.controlbooth.com/forums/...-lighting-system-dmx-over-ethernet-ideas.html .

The Enttec device mentioned above is the D-Split. I don't think we've ever had a negative report on this opto-splitter, especially considering the price.

Alright so I retract the router/hub/switch idea. However the Cat 5 (or better) daisy chain and RJ45 to DMX adapters works great and is an excellent way to save money if you don't have a huge system and it isn't going to be moving around a lot.

I have had issues with the elation branch 4 splitter before. I had a similar problem and I ended up fixing it by changing out the splitter but originally opened up the splitter and did some creative patching so it would y all of the inputs and outputs together. Yes this goes against the rules of dmx but the show must go on and it was replaced with a Doug fleenor splitter.

It's not a terminator, DMX issue; nor is it unexpected behavior. Sounds like when the fixtures lose DMX, they revert to sound-activated or stand-alone or macro mode. The solution is to remove power to the fixtures before turning off your DMX console. Perhaps there's also a way to disable the stand-alone functions in case of loss of DMX. http://www.elationlighting.com/pdffiles/opti_tri_par.pdf

i have this issue on a few of the DJ grade lights. They default to an auto program. What sucks is if you lose DMX during a service. All of the crap lights start freaking out.

If that's what is happening then try putting every unit in the chain is in "Slave" mode, assuming these fixtures have such a setting. Without a master, they won't do anything.
