DMX512 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 120-ohm 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. 3 pin XLR connectors are more popular than 5 pins 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 (+), Pin4/5:
not used
Pin configuration
Pin 1 = Ground
Pin 2 = Data compliment (negative)
Pin 3 = Data true (positive)
