Connect the provided power cable to the "POWER IN" port on the rear of the fixture and then to a suitable grounded power outlet. For daisy-chaining multiple units, connect the "POWER OUT" of the first fixture to the "POWER IN" of the next.

5.3 DMX Connection (Optional)
To control the fixture via DMX, connect a DMX controller to the "DMX IN" port. For multiple fixtures, daisy-chain them by connecting the "DMX OUT" of one fixture to the "DMX IN" of the next. Ensure the last fixture in the chain has a DMX terminator (not included) for stable signal transmission.
