James Aleksic Posted November 10, 2014 Share Posted November 10, 2014 Hello, I have an LED Parcan (cheap little thing, cost me around £35), and it seems to have confused red and blue. I am controlling it via DMX, and when I tell it to go red, it goes blue, and when it tell it to go blue, it goes red. The green works fine, as does the channel controlling dimming / strobe. The channels seem to be working fine, but just not in the right order! It is a 4 channel fixture, with the channels being Red, Green, Blue and Dimmer/Strobe, but it seems to think it is Blue/Green/Red/Dim. Just wondering if anybody else had ever had the same issue, or had any ideas about how to fix it! Thanks in advance! Link to comment Share on other sites More sharing options...
david.elsbury Posted November 10, 2014 Share Posted November 10, 2014 What controller are you running? Sounds like the personality is incorrect Link to comment Share on other sites More sharing options...
Ynot Posted November 10, 2014 Share Posted November 10, 2014 What desk or program are you using to control the fixture? It could well be as simple as the personality in the desk being set incorrectly. Link to comment Share on other sites More sharing options...
James Aleksic Posted November 10, 2014 Author Share Posted November 10, 2014 It's for a Christmas light show, so I am running Vixen 3 on a Windows 8 PC, with an Enttec Open DMX interface. I have 3 other led parcans which are all working correctly. It seems that changing the profile on the PC to BGRD makes the light work as planned, so I'm now really confused as to what the light is doing!

JTilling Posted November 10, 2014 Share Posted November 10, 2014 I have the same problem with some cheap par cans I own running a chauvet obey 3 desk (if you can call it a desk) The faders don't match up with the par can at all other than green I think. I think its just something to do with cheap parcans more than to do with the desks. Mine doesnt even have 9 dipswitch's but instead have 8 so DMXing is a little interesting.

Jivemaster Posted November 10, 2014 Share Posted November 10, 2014 Sometimes it's one of the features of buying economy kit from China four lights with four different personalities. Link to comment Share on other sites More sharing options...
DrV Posted November 10, 2014 Share Posted November 10, 2014 Or it may simply be that plugs inside are jumbled up... or is that too simple? Link to comment Share on other sites More sharing options...
Don Allen Posted November 10, 2014 Share Posted November 10, 2014 It is probably a mixup of the wires. If you look at PAR64 LED Wiring you will see a small white plug with wires going to it. These wires can be put in the wrong order. On the back of the plug are small slots, where the tab of the plug insert springs out to lock the insert and wire into place. Take a picture of the wires before you start, as a reference. Using a small jewellers screwdriver, push the tab down while carefully pulling the wire out. Do this for the red and blue wires. Carefully bend the tab back out away from the insert so it can act as a holding tab again, then push the inserts into their correct slot. Although this is low voltage wiring and you will do this with the power off, do not open up the LED Par can unless you are competent and confident to do so. Or you can cut and rejoin the two wires that need swapping using a tag block or connector. Link to comment Share on other sites More sharing options...
DrV Posted November 10, 2014 Share Posted November 10, 2014 ... Do this for the red and blue wires. But if he tells you his name is Juggernaut, walk away... :-) Link to comment Share on other sites More sharing options...
marktownend Posted November 11, 2014 Share Posted November 11, 2014 I've got some unbranded LED kit that's basically the same as some cheap branded units, except that whereas the 'branded' ones use 4 channels on R/G/B/intensity the unbranded ones go intensity/B/G/R - my guess is that someone has just read the channel list from right to left...

MarkPAman Posted November 11, 2014 Share Posted November 11, 2014 Some cheap ones I've got have inline fuse holders on each of the RGB lines, so can easily be swapped around. Link to comment Share on other sites More sharing options...
norty303 Posted November 11, 2014 Share Posted November 11, 2014 I bought 6 PAR56 1W led from thomann a few years back where one fixture had a colour swap on blue and red. The plugs had just been connected wrong on assembly. Easily fixed by switching the plugs. Link to comment Share on other sites More sharing options...
