Vista 3 and ETC Unison

Trying to set up ETC Source 4 Luster and ETC Luster D40s in Vista 3 r.2.
What power channel do I need to patch in to make the Source 4s and D40s stay on through the Unison Relays and still be controlled for Color and Dimming?

The power and fixture are 2 separate things

Patch a generic non dim to the hot power address
You can then control thease like a binary on/off switch for the power

Then patch your lusters to their address as normal to control them
