Based on
these instructions, or at least what I can decipher from the Chinese translation, you want to set it for Mode 35 [DMX DECODER] mode, and then jam on the PARA
button to set the starting
DMX address. Judging from the text below, it's possible you may have to manually set the
DMX address for each of the 4 parameters, but usually you just need a single starting
address.
Looks like the other "
DMX MODE" is for running built-in chases and looks and isn't what you want. Possible the state you're in already if you're seeing a constant glow. This
driver is built for
LED's and shouldn't need a
ghost load.
If in doubt, set it for
DMX and run
DMX 1-512 up to full and see what happens. Usually something like this would ship defaulting to Ch1 but experimentation is half the fun of buying generic Chinese electronics! You're lucky to have instructions at all even if it's in broken English.
