OK, using that logic, the channel number only goes to 512, so I am assuming that is the absolute offset address.
Still using my example of universe 50 starting address 24491, and the board expecting to see output on 24500, wouldn't I still be using channel 10?
I'm a bit confused on what should be expected to be done?
Add DMX skull, Skull Config, select movements, adjust the channels, everything should be lined up in xlights (or does that not matter?)
