I'm having an issue with flickering LED fixtures. I get flickering and strobing on one type of fixture in particular (Elation ELED Fresnel 150) whenever I'm sending lots of DMX data to another fixture, like animating a mover or flashing RGB LEDs. I thought it was a termination issue so I added a terminator, but it didn't work. So then I started pulling cables while the board (ETC Element) sent a move effect to one of our Design Spot 250 Pros, until I got down to just one fresnel at the beginning of my chain, with nothing else. It was still flickering! I have no other 5 pin DMX cable to test it with, otherwise I would switch it out, but the first fixture is only about 30 cable feet away from the board.
The interesting thing is that I have 8 of these fresnels in the universe, but only the 4 at the beginning of the loop exhibit this behavior. None of the other fixtures, which include Elation Tri White Pars, TVL2000, and DLED RGBAWs, exhibit this behavior. This also happened with another board, the Elation Show Designer 2, but I chalked it up to a board issue. Since it's happening with the Element, too, I think something else is going on.
