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
