DMX Cabling

The DMX protocol requires using special data cables to accommodate for the high speed digital signals it uses. Despite their apparent similarities, data cables are electrically different from standard microphone cable because they can carry high frequency digital signals and are less prone to electromagnetic interference. You can purchase CHAUVET® certified DMX cables directly from a dealer/distributor or make your own DMX cable.

If you choose to make your own DMX cable, you must use a data-grade cable such as the Belden 9841, which has the following electrical characteristics:

Type:

shielded, 2-conductor twisted pair

Maximum capacitance between conductors:

 

30 pF/ft

Maximum capacitance between conductor and shield:

55 pF/ft

Maximum resistance:

 

20 ohms/1000 ft

Nominal impedance:

 

100~140 ohms

DMX Connectors

Each DMX cable must have a male XLR connector on one end and a female XLR connector on the other end. The DMX protocol indicates that the XLR connectors must have five pins. However, most lighting fixtures use the 3-pin XLR connector. The pin out of the 3-pin XLR connectors in a DMX cable is a follows:

As it is common with digital signal links, the DMX daisy chain uses a terminator to reduce signal transmission problems. This terminator consists of a 120 Ω, ¼ W resistor connected to pins 2 and 3 of a male 3-pin XLR plug as shown below. This plug connects to the DMX Out socket of the last DMX fixture in the daisy chain.

120 ohm ¼ W resistor between pin 2 (DMX -) and pin 3 (DMX +) connected to the output of the last fixture

Do not allow the common wire of the DMX cable to come in contact with the fixture’s chassis ground. This could cause a ground loop, which could make your fixture perform erratically. Test all DMX cables with an ohmmeter to verify the correct polarity of the wires and to make sure that they are not shorted to the shield or to each other.
