Connect Power and Data

If you ordered a Source Four fixture without a power connector, first see Wire the Power Connector (If Needed).

  1. Attach 5-pin XLR cable to the DMX In connector (A) if you are using external control.
  2. Plug the XLR cable (if using) into the DMX source or data daisy-chain.
  3. Use the Power Thru and DMX Thru connectors (B) to connect other fixtures using the following guidelines: 
    • Link up to 5 fixtures via Power Thru connector when used with R20 Relay Module, ER15 Relay Module, or Unison Echo Relay Panel (consult breaker-trip curves when used with other equipment). When linking fixtures, do not exceed the rating of the power connectors (20 A in 120 V/60 Hz regions and 16 A in 240 V/50 Hz regions).
    • Link up to 32 device loads on the DMX daisy chain. Source Four LED Series 3 fixtures are self-terminating when a DMX cable is not connected to the DMX Thru connector.
  4. Supply power to the fixture by attaching the power cable to the Power In connector (C), and then plugging the power cable into AC power (100–240 VAC, 50/60 Hz) on a non-dimmable circuit.
