Colorsource Pars come to full when Eos shuts down

This has been an ongoing situation for about a year, and I can't seem to find a logical explanation.  I have three pipes with 6 each Colorsource Pars as diagonal backlight, each pipe with its own opto-splitter and all three in the same gateway.  If I leave the rig powered on but shut off the desk, sometimes there's no problem, sometimes one pipe's worth of CS Pars will stay on at full open white, and tonight all three pipes and all 18 fixtures came on.  I powered the Eos Ti back on and off, the lights were off, but about 5 minutes later they returned to full.

We have never used any presets or sequences with these fixtures, they get hung in different locations and re-addressed frequently, and sometimes sit on a shelf for a couple weeks at a time.  I have to leave the rig powered for several weeks sometimes, because our 6 I Cues lose focus pallet references when powered down.  My solution for now is to leave the power and the desk on while in a show run, but that's not ideal for long runs.

Can anyone find a rhyme and reason for this to happen in the first place, and in such a non predictable pattern?

 

Thanks all

    Corey, thanks again. Today I came in early and checked each pipe and as you thought, one fixture per pipe was set to Preset Mode with power off. When I hit the MODE button again all the CS Pars went out. Funny thing though, when I hit the MODE button again, not only those pars, but 5 Vivid D60's and 2 LED 2's also came to full. They weren't on with the original problem.

    Anyway thanks for walking me through the fix.

    Hi Tom,

     

    I am glad you got that figured out.

    All ETC LED Fixtures which are RDM-able (CS, S4 LED and Desire) will react to a preset recall

    on the same unmodified DMX line. So if you recall preset 3 on a CS Par on a pipe which has

    also Desire and S4 LEDs connected to it, then also the Desire and S4 LEDs will recall their Preset 3

    at that same Moment.

    Since I am not there, I cannot tell you why the Desire and S4 LEDs didn't go on when you originally noticed the CS Pars jump on,

    but I can guess that maybe they did not have power on or did not have their DMX connected at that exact moment 

    the CS originally got their preset recalled, and then they won't recall a present preset when they are connected later.


    Clear? Have fun with your LEDs and the plethora of colors available!

    Thanks again Corey, I'll delve into the D60/LED2 more, as the power and data were present at first loss of dmx. You've been a big help and yes, we are enjoying the benefits of a newly hybridized LED/conventional lighting plot, adding four more LED 2 systems to our rig next month!

    I don't mean if they had power/dmx when the power was orginally lost, rather if they had power and dmx connected to the CS Par when the CS Par recalled the Preset originally. That was probably not the case. Those Desire/LED must be connected with dmx to the CS Par and powered in the exact moment when the CS Par recalls his preset. If not, then they won't have recalled their preset. Just because a fixture is in a preset and you connect new fixtures, they won't automatically match their presets to the ones they are connected to.

    Ok yes that makes sense. All the LED fixtures on each location are powered together and share the same dmx data chain, so when the preset in the CS Par was recalled, the Seladors and LED2s also came on to their background presets.
