Hello collective wisdom! I am new to the world of RGB and have 16 sets of 2811 string pixels with 85 pixels on each string. I am connecting them to a p12s E1:31 controller. I have plugged in my LOR dongle and the listener detects the 9 universes I am wanting to run (2 sets of strings joined in each universe). I can only get 1 set of lights to work. Universe 1-set 1 work OK within LOR when I play a sequence and flick quickly RGB in test mode on the p12s. I can't get any other sets to work, or even when I join another set to the ones working, they will not light up either! I am joining the data cable to set 2 (universe 1), and have tried joining the 2 power wires with no joy. Also tried connecting a new wire from the 12v power to the wires for power (power injecting?). I have all the strings set as 170pixels, ticked for active and in the string effects I have ticked for active on the strings and set them for 170 pixels too. I have the speed set at 2400. Can anyone give me an idea where I may be missing something?
