One last question, the 4 port passive hubs they always take the first pair for their universe? So if I wanted them to be on Universe 2 I would need to make a cable putting the second pair first?
yes, the 4-port only takes the first pair (first universe). this allows you to use any of the following as input: (1) a USB pixelnet dongle, (2) a smart hub pixelnet out, (3) a (POWERED) SSC output from the smart hub, or (4) an EtD.
to select a different universe, you can use a Combiner kit... or you can also modify a cable to grab your needed pair of wires coming from the source hub and connect them to the first pair (orange/white, orange) on the input to the 4-port hub.
