Below is a list of pixel protocols supported by RC4 DMXpix & LumenDimPix at this time :

WS2811/2812*
WS2801
SK6812RGBW*
UCS8904RGBW*
TM1814RGBW
APA102
APA104 (RGB, RGBW)
LPD8806
HD108
MY9231 (with optional clock adaptor)

* These protocols are very similar, and there are many other string types that use these protocols. If your pixel string has 3 wires (power and data, no clock), try these options first.

Still unsure, please submit a technical support ticket.
