Power Connection:
Connect the provided power cable to the 'POWER IN' port on the rear panel and then to a suitable power outlet. The unit supports power linking, allowing multiple fixtures to be powered from a single source using the 'POWER OUT' port.
DMX Connection:
For DMX control, connect a DMX cable from your DMX controller's output to the 'DMX IN' port of the first fixture. To daisy-chain multiple fixtures, connect a DMX cable from the 'DMX OUT' port of the first fixture to the 'DMX IN' port of the next fixture, and so on. Ensure the last fixture in the chain has a DMX terminator connected to its 'DMX OUT' port.
