Holiday Coro is no longer stocking the DMX programming dongle. Its for setting the channel on the 3 channel DMX controller for dumb pixels. I fried mine... Anyone have one they would part with or know of an alternative. Dave at Holiday Coro said the LOR usb485 would work but I have had no success with it. I have about 20 of these I use for spotlights and my pumpkins. Just don't want to have to replace them.
