Snap to black problems

Can anybody tell me about snapping to black using an ION with the latest version of software?

Problems are as follows: I am getting mixed results with snap to black commands. I am controlling 112 ColorSource Spots and 4 ROBE Robin DL4S's with an ETC ION V2.3.3. Sometimes I WILL get an immediate intensity out and sometimes I will get a 1 or 2 second FADE to black despite a cue time of 0 and no discrete timings but it is not consistent through the whole rig.

This problem is present with Cue times of 0 and when manually sending a ch @ OUT command.

My system is sending data to the ColorSource spots over sACN to ETC Nodes / single channel gateways and out from there to DMX. The ROBE's are stricly sACN, no gateways inbetween.

I don't believe it to be a data speed problem as a straight to black command would result in a lag rather than a fade out.

Any insight would be appreciated.

Edit: Just an update on this, I only experience a slow fade out when snapping to black when the instruments are at low levels. This does not seem to be a problem when they are a full then go to black

    Is it consistently one unit? One line of dmx? One node? Did you try swapping out the cable and or node to see if it stays consistent? Truly inconsistent did you try taking things offline to see if it stays the same?

    Hi Jay, I isolated the instrument and even took a spare and used a dmx tester. It seems that with the DL4S any intensity below 58 percent causes the emitters to fade rather than snap. I still haven't had time to dive in to fully testing the ColorSource Spots in this manner but they behave similarly from what I have observed.

    I have not figured out if the spots all behave the same on one node or on the same loop but I will check that out.

    I believe that the starting intensity is what is causing it but again, have to test that specifically.

    Thanks.

    When looking at the dmx stream via the dmx tester are you seeing that fade for the DL4S below 58%, or is only the fixture behaving accordingly? If you are seeing it on the data line I would try saving your show and doing a deep clear and then restore your show and try again. If you still see the problem this could be a bug with something on that profile maybe... If it is not showing up on the tester, but it is on the fixture that would point to a fixture issue... Let us know if the CSS do the same...

    Hi Seth! I am so sorry for the huge delay in response, opening night was last night and of course the last 48 hours were hectic.

    I have attempted to do as you suggested and since then I have discovered the following:

    The CSS's will snap to black only if intensity is 40% and above
    The Robe DL4S's will do the same when the dimmer curve is set to linear but will only snap to black at 58% and up if the curve is set to square law.

    I've determined that it's not the console and have also emailed etc tech service and ROBE.

    Thanks!
