5. How to Control the Unit

5.1 DMX 512 Connections

The DMX512 is widely used in intelligent lighting control, with a maximum of 512 channels.
1. Connect the fixture together in a "daisy chain" by XLR plug cable 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
2. The DMX output and input connectors are pass-through to maintain the DMX circuit when one of the
units' power is disconnected.
3. At last fixture, the DMX cable has to be terminated with a terminator to reduce signal errors. Solder a
120Ω, 1/4W resistor between pin 2(DMX-) and pin 3(DMX+) into a 3-pin XLR-plug and plug it in the
DMX-output of the last fixture.
4. Each lighting fixture needs to have an address set to receive the data sent by the controller. The
address number is between 0-511 (usually 0 & 1 are equal to 1).
5. 5 pin XLR connectors are more popular than 5 pins XLR.
5pin XLR: Pin 1: GND, Pin 2: Negative signal (-), Pin 3: Positive signal (+)
