1. If your controller has a 5-pin DMX output, you need to use a 5-pin to 3-pin
adapter cable.
2. Link the fixtures together in a “daisy chain” by connecting XLR cables from
the output of the fixture to the input of the next fixture. The cable cannot be
branched or split to a “Y” cable. Inadequate or damaged cables, soldered
joints, or corroded connectors can easily distort the signal and shut down
the system
3. The DMX output and input connectors are pass-through to maintain the DMX circuit
when one of the units’ power is disconnected.
4. At the last fixture, the DMX cable should be terminated to reduce signal
errors. Solder a 120 ohm 1/4W resistor between Pin 2 (DMX-) and Pin 3
(DMX+) into a 3-pin XLR plug and connect it to the last fixture’s DMX output.
5. Each lighting fixture must have its address set to receive data sent by the controller.
The address number is between 0-511 (usually 0 & 1 are equal to 1).
6. 3-pin XLR connectors are more common than 5-pin XLR.
3-pin XLR: Pin 1: GND, Pin 2: Negative signal (-), Pin 3: Positive signal (+)
5-pin XLR: Pin 1: GND, Pin 2: Negative signal (-), Pin 3: Positive signal (+)
Pin 4/5: Not used.

The DMX512 is used widely in intelligent lighting control, with a maximum of 512 channels.
