Unable to assign DMX number to fixture

[Wade]

I have assigned 4 Studio Color 575s to my Bullfrog console. I was able to assign fixture 1 to DMX B001, but I could not assign fixture 2 to DMX B002 - it auto assigned to DMX B018. Am I missing something here? I thought this would be easy but I know I have overlooked something. Thanks for any help you can give.

The fixture type you have obviously requires 17 channels of DMX for all of it's parameters (dimmer, cyan, magenta, yellow, pan, tilt etc.). When patching fixtures, the range of DMX channels that each requires cannot overlap with that of another fixture.

 

If you patch the first fixture to Universe B DMX address 1 then the next available address will be universe B DMX address 18, the next DMX address 35 etc.
