Hi there,

Wondering if I can get some input on this problem...

I have patched a matrix of 3 channel RGB LED fixtures. They have worked great in the past but I am now seeing some issues with them.

The Problem: The fixtures behave as though I am sending them random bits of information. They respond to my instructions (all fixtures red, all fixtures blue, all fixtures 0 etc.) but are seemingly, in addition to that, reacting to information that I am not intentionally sending. Many of the LEDs strobe and change colors randomly as I am sending them data. I still have control of turning them off and on, but if I send them anything information they automatically act up.

I have done all the hardware trouble shooting I can think of. The fixtures are not running on too much or too little power, and they respond find to other consoles. I've scaled back the matrix to only 1 fixture and the problem persists. Other fixture types work great with the interface I am using. There's no issue with the DMX cables I am running, either. Am I correct to conclude this is a software issue?

I've repatched the entire matrix many times. I've created new shows and patched the entire matrix and only one fixture of the matrix. I have restarted and repatched the software and interface several times. One thing I haven't done is re-installed SS2.

Any ideas as to what my problem is, or how I should proceed in trouble shooting?

Thanks,

1.Open the 3D visualiser or DMX output window and look at the levels, this will tell you straight away if it is a software issue or a dmx interface/fixture issue
2.Open tools.exe found in the suite2 root directory, click the test tab and move the laders on the left, do you still have the same problem?

The issue ended up being a set of fixtures having grounding issues. It was not a software problem.
