Fixture update Mini LED PAR

I've been struggling with this particular fixture for a while. I believe it's the profile having strobe feature before the intensity, but I'm struggling to write the appropriate profile myself. Hoping you could help. Trying to have the profile up and running by October 14th if possible. Thanks.

  • The profile with 5 addresses should be really simple to write yourself. Provided the fixtures really behaves as this manual suggests...

    Can you post a screenshot of what you tried?

  • I think the problem may have to do behaving unlike the manual suggests. I tried as the post below suggested with little success. When put in IRGBS, strobe seemed to be in dmx value 3, not 1, but I could never get all the values working with any combination after that. 

    Next I tried just RGB. The intensity ended up being the strobe, R was intensity, G was Red, B was Green. So I went to RGBA. All of the values line up, with A taking the strobe feature. It doesn't function perfectly, but it is usable. The problem that I've always had still persists. Random flashes or possibly a very slow strobe. I figured it had to do with cross talk across the values on an improper fixture profile.

  • Make sure your fixture is switched into DMX mode, It looks like some of those dip settings might be a little funky and mess with your data input.

    Picture states that strobe is from 16-255. Might be no strobe if set 1-15. 

    If you are going to build your own profile, I suggest something like this:

    Number Param Size DMX ... Range
    1 Strobe Effect Rate 8bit 1 2
    2 Intens 8bit 2 1
    3 Red 8bit 3 1
    4 Green 8bit 4 1
    5 Blue 8bit 5 1

    In your range for strobe

    Min Max Label
    0 15 Off
    16 255 Rate

    if you want to troubleshoot the easy way if the fixture isn't behaving as you think it should, then just patch all the channels dimmers to it. Start with them all up and slowly take one out. whip out a pad and write down what's changing for each dimmer. (8bit fixtures only, 16bit gets tricky that way)

  • The new profile puts the intensity wheel as the strobe rate and intensity together. which is what happened when I split them out as "dimmers" as well. it was controlled from 4 channels. In both instances there would be random flashes. While I know this sounds like a problem with the fixture itself, there are 13 fixtures in all and they all have the flash issue. groups purchased in different years. I'm currently only using 1 for testing but later this week I can get all 13 in a chain and test if the flashes are random or synchronized. 

    Oddly I have been testing with the fixture addressed to dmx channel 2. turned the #1 dipswitch ON and the address didn't change. Based on some research, even though its says dipswitch 10 is DMX Mode, there was some information on the internet that lead me to believe 1 and 10 need to be ON. Unfortunately it didn't correct the flashing problem. 

    Thank you everyone so far for the help! troubleshooting the cheap stuff can be a headache and a half. 

  • If there is doubt about the actual base address of the fixture (ie what the dip switches are doing) make sure its patched at an address that there is nothing immediately below or above it as if you are off by one then another fixtures settings could effect it. 

    As Cameron said above try diagnosing it by patching it as a set of single address dimmers and just work out what the real assignments are (patch one of them below the address you think the device is set to incase you are off by one on the dip switches).

    I've dealt with a lot of cheap Chinese moving heads and the dmx sheet is almost always wrong, so have to go through that process to build the profile correctly.
