Artnet network:
2.0.0.10
255.0.0.0
blank gateway.

Additional network
192.168.88.x
255.255.255.0
192.168.88.1

Todd - It isn't a launch order issue. But that is a good idea. However, I will leave cat running, hide the hud on the main display, enable the additional network, and then as soon as its enabled, the artnet starts going nuts.

Is it because I don't have a gateway address on it? It really shouldn't matter though.. still listening to the same data. Oh and my hog is set to unicast only to that 2.0.0.10 address with universes 0,0-0,2.
