This is a DMX controller that tries to force fixtures of all types and brands to plug into a single, generic fixture profile that doesn't come close to fitting ANY of them..Eurolite's unique concept is that the DMX channels of all fixtures should start with R, G, B and dimmer, use exactly 18 channels, and end with 8-bit pan and tilt channels. Moreover, users should start out with no more or less than 32 predefined fixtures, none of which can be removed. Of course, if your particular set of light fixtures don't happen to fit this boldly simplistic plan, you are welcome to remap or delete each and every dysfunctional channel in each and every one of your fixtures, using the remarkably tedious and counter-intuitive push-button interface provided by Eurolite, which they evidently designed with a completely different purpose in mind.
