Can anyone tell me if there's away a DMX hardware controller connected to a Ultra DMXking adapter into a computer, run along with DMXis controlling lights at the same time, on the same computer? Is there an address I should use to connect devices or something?
You just need a dmx combiner. You wouldn't run the DMX out from a hardware lighting controller into a computer.
DMX combiners usually have 2 options, Higher value or Latest value.
Higher value works when the hardware controller deals with conventionals and the other controller for moving fixtures. If a cue on console A has channel 1 at 50%, console B can increase channel 1 but never decrease it below 50%.
Latest value works when you want either controller to have control on all the lights. Usually when one is a backup.
It should in theory also be possible to have the computer act as a combiner. You'd need appropriate software (which may not exist for your particular setup, or at least may not be readily available); I'd think such functionality would most appropriately be incorporated into whatever program you're using to control the lights from the computer, although it might also be possible to incorporate functionality into a driver and so make it independent of the lighting control software. I doubt it's a particularly common use case, at any rate, so likely not a standard feature.
A standalone DMX combiner is in my opinion a better solution, more likely to be trouble-free and certainly more robust in the event of a computer crash.
LightFactory is a software package that can act as a combiner. It can accept DMX from an Ultra DMXking and merge it with an outgoing DMXuniverse on an HTP (Highest Takes Precedence), LTP (Lowest Takes Precedence) or ITP (Input Takes Precedence) basis.
