14-7. DMX512 ConnectionsThe DMX512 is widely used in intelligent lighting control, with a maximum of 512 channels.1. If you using a controller with 5 pins DMX output, you need to use a 5 to 3 pinadapter-cable.2. Connect the fixture together in a “daisy chain” by XLR plug cable from the outputof the fixture to the input of the next fixture. The cable cannot be branched orsplit to a “Y” cable. Inadequate or damaged cables, soldered joints or corrodedconnectors can easily distort the signal and shut down the system3. The DMX output and input connectors are pass-through to maintain the DMXcircuit when one of the units’ power is disconnected.4. At last fixture, the DMX cable has to be terminated with a terminator to reducesignal errors. Solder a 120-ohm 1/4W resistor between pin 2(DMX-) and pin3(DMX+) into a 3-pin XLR-plug and plug it in the DMX-output of the last fixture.5. Each lighting fixture needs to have an address set to receive the data sent bythe controller. The address number is between 1-512.6. 3 pin XLR connectors are more popular than 5 pin XLR.3 pin XLR: Pin1: GND, Pin2: Negative signal (-), Pin3: Positive signal (+)5 pin XLR: Pin1: GND, Pin2: Negative signal (-), Pin3: Positive signal (+)Pin4/5: Not Used.
