So am I correct in my understanding that you always program channels with a starting value between 1 and 4096 regardless of the pixelnet universe? I can't believe I didn't know this already but probably because I had under 4096 (1 pixelnet universe) in prior years it didn't really matter.
So for example, if I want to start a display item at pn ch#4097 ... This would be set as starting channel 1 and I just jumper the Zeus (or ssh) to pn univ#2 ... Which in the software can be referred to s pixelnet channel 4097.
Also, do you need to have the jumper set to pn univ#1 when running the ss utility?
In the DMX world, devices have channel assignments from 1-512, multiple DMX universes can coexist, often called "networks".
Similarly in the Pixelnet world, the devices have channel assignment from 1-4096, and again multiple universes can coexist.
The devices know nothing about the other universes, only their place within their current universe.
If your dongle is sending packets over universe 2, the hub is assigned to #2 using the jumpers, then the SSCs will pick up the packets -- they won't know they are on universe 2... the hub knows that by the selection of the 2nd pair.
