DMX is, by design, "a universe."  512 channels

You set the Start Channel for that Universe. Usually  1 or 513 or 1025.  Those would be Universe 1, Universe 2 and Universe 3 if you think about it that way.

ok so I have 37 universes so for the pi cap dmx port I set the start to 18946 with 16 for channel count right
I do that and go to test display on pi and put start channel at 18946 and just to test I leave the last channel off 18961
when I do that all channel on ac control come on By the way I am using a lynx express controller

For universe 37, I get 18433 as the start channel
 ((37 - 1) x 512) + 1
