For DMX control, connect a DMX controller to the 'DMX IN' port on the fixture using a 3-pin XLR cable. If connecting multiple fixtures, link them in a daisy chain from 'DMX OUT' of the first fixture to 'DMX IN' of the next. Ensure the last fixture in the chain has a DMX terminator installed (not included) for optimal signal integrity.
