I am trying to program my first 128 node string. I am not getting any of them to light, flash, or otherwise while trying to program the channels. I am wondering if it matters which end of the string is connected and if I need to count the nodes before trying to set the channels. I saw where someone had bad nodes, but it appears some were lit and it seemed taht node count mattered. I measured 12V on the string and 7 volts on the chips. Seems like I have power end to end and at the controller.
Need HELP!!!!
