I am relatively new to the RGB smart pixel world, but here is my conundrum....I have a couple different types of WS2811 pixels (all 12V 8mm bullets, rectangles, and C9s with the WS2811 protocol). I tested them together to make sure they would work together and all was fine until I started laying it all out and now they aren't. It seems my C9s http://www.holiday-light-express.com/light_information.php?partnumb=RGB-WS2811-C9tech-50&stock_printout=39 in Stock are the crux of my issue as the bullets and rectangles, both of which I purchased from holidaycoro.com work seamlessly together. The C9s however, will receive data from the bullets and rectangles and display fine, but to continue on and put a bullet or rectangle after the C9s, I get nothing. Also, some of the C9s can't transmit very far....not even up the 5' leaders that they came with, but if we shorten it to a foot it works fine. Voltages are fine at the end of the string at 11V All my connectors are weatherproof, soldered using silver solder and in wired in series. I was planning on using the 8mm bullets as null repeaters when I had long runs between strands, but I can't get them to talk to each other anymore. Any help would be appreciated as I am not even sure how I am going to lay this out off my Pixlite4 if I need a new output for every strand.
