i found this out the hard way..
when i bought my smart strings, the coop didn't finish yet for the smart strong hub, and controllers, so i purchased a dmx device from ray to test my smart strings. it used the 3pin xlr type adapter for dmx in/out. while i was making my adapter cable from rj45 to xlr, i didn't take in consideration about the male female xlr plugs being backwards. when i turned everything on, everything was white, and the sequence made everything darken. when i saw a sequence that was ramping up making the lights darken, then i realized my data lines were backwards.
