[QUOTE="Plan-B, post: 125828, member: 1097"] Checked and double checked Fugley. This was my first thought as well, but I think I have all settings in order. Thanks for the comment. Thanks Terry. That helps put my mind at ease. Before reading your post, I put my cheap multimeter in series with the strip and got a reading of 4.1 Amps. Very close to what you said to expect. I feel fairly confident now that I won't burn my kids room down. I was so worried about the current draw, I dropped the ball and forgot to test the voltage drop. I'll have to test that as well tonight. I actually don't have BI hooked up at all. As I understood it, BI is a backup data channel and not really needed for operation. I will try connecting it to ground and see if there is any improvement. Currently, I'm using a cheap, 6" breadboard jumper to connect D4 of the controller directly to DI on the strip. I'm pretty sure those are only 28 AWG. With the short, 6" run, I thought it would be sufficient and I wouldn't require a level shifter or sacrificial pixel. Maybe that's my issue and the 3.3v off the board is not cutting it for the 5v data line? I've also read a few places that putting a low ohm resister in series with the data line can help smooth out signal. Unfortunately, I have nether resistor or level shifter to test the theory out.

The title of our introductory lighting manual contains a three digit number. What is that number? Clue: Display basics forum
