7. DMX 512 Connections
Connection mode:
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.
2. The DMX output and input connectors are pass-through to maintain the DMX circuit when one of
the units' power is disconnected.
3. The last units DMX cable has to be terminated with a 120 ohm 1/4W resistor between pin 2 (DMX-)
and pin 3 (DMX+) of a 3-pin XLR-plug and plug it in the DMX-output of the last unit.
4. Each fixture unit 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 (+)
Pin 4/Pin 5: Not used.
7. Troubleshooting
Following are a few common problems that may occur during operation. Here are some suggestions for
easy troubleshooting:
A. The fixture does not work, no light
1. Check the connection of power and main fuse.
B. Not responding to DMX controller
1. DMX LED should be on. If not, check DMX cables to see if linked properly.
2. If the DMX LED is on and no response to the controller, check the address settings and DMX polarity.
