The DLA hub can only do ONE pixelnet universe at a time.
For programming your SSC, it is recommended you do this from universe #1.
when selecting a universe, make sure that BOTH jumpers are set to the same number...
universe #1 -- set first jumper to 1, and the second jumper also to 1
universe #2 -- set first jumper to 2, and the second jumper also to 2
universe #3 -- set first jumper to 3, and the second jumper also to 3
universe #4 -- set first jumper to 4, and the second jumper also to 4
within the selected pixelnet universe you can also select a 512 channel page and have it be available as a dmx universe.
regardless of how which pixelnet universe you select -- the SSC is always configured to a start channel from 1-4096. the SSC only sees its small world where channels are in that 1-4096 range.
regardless of which page of channels exposed as a DMX universe, the DMX-attached devices are always assigned a channel from 1-512. the DMX devices only see an even smaller world where channels are in that 1-512 range.
