Lighting Controls for
Standard DMX-512 devices use 5-pin XLR jacks. A Male XLR is a device's input and a Female XLR is a device's output. They are wired as follows:
5-pin XLR Signal Pin 1 Signal Common
Pin 2 DMX Data -
Pin 3 DMX Data + Pin 4 Auxiliary Data - Pin 5 Auxiliary Data +
NOTE: Only a few legacy DMX products that supply feedback to the lighting console use pins 4 and 5. These products include IPS brand dimmers and possibly others. The vast majority of installations do not bother to electrically connect anything to pins 4 and 5. Also, products that use RDM protocol do not need Pins 4 and 5 connected.
Some DMX equipment uses 3-pin XLR jacks. They are wired as follows:
3-pin XLR Signal Pin 1 Signal Common
Pin 2 DMX Data - Pin 3 DMX Data +
Some older 3-pin fixtures from Martin Professional are wired with pins 2 and 3 reversed from the "standard" configuration.
Reversed 3-pin XLR Signal Pin 1 Signal Common Pin 2 DMX Data + Pin 3 DMX Data -
High-density LED and some Architectural DMX-512 products use RJ45 jacks. If they follow the accepted ESTA standard, they are wired as follows:
RJ45 Jack CAT5 Color Code ESTA Standard Signal Pin 1 White/Orange DMX Data + Pin 2 Orange DMX Data - Pin 3 White/Green Alternate Data + Pin 4 Blue n/c Pin 5 White/Blue n/c Pin 6 Green Alternate Data - Pin 7 White/Brown DMX Ground Pin 8 Brown Alternate Ground
