PhilW0 Posted December 11, 2018 Share Posted December 11, 2018 Hi, there. A few years ago I bought some Cosmic Color Bulbs (5 controllers, each with two strings) but never had time to set them up until this year. I tested all the units (one was bad on one side) and I am using three of them on a tree in my yard, with five light strings. It's a simple spiral wrap of the tree. I tested all three of those controllers just prior to installation without any issues. Once I had them on the tree and wired to my PC (same PC I tested with), I had some issues. Using the hardware utility, two strings respond to "all on" commands (e.g. units 1 and 2 both respond, with one unit selected in the HU). I have tried resetting the unit numbers with HU and it seems to work individually but when I have the three controllers all hooked up I get this behaviour. Also, when running some sequences I get flashing on one of the strings on the first unit. If all lights fade from one colour to another simultaneously it is fine, but when I do chases or other effects I get flashing. I should mention I did reset the two confused controllers with the internal button (pressed during power-up) before I used HU to reset unit numbers. I have the red USB RS485 adapter, and about 90' of cat6 cable between it and the tree, then about 6' each from one box to the next. The kits I bought were the CB100D DMX and controllers do have the latest firmware (1.21 I believe). To get through Christmas I am just using simple colour fades but would love to be more elaborate in my sequencing. Also, I want to get more lights to put on the house and elsewhere but given this problem not sure I really want to keep investing. Any ideas, please?
