Data Cables

The luminaire is equipped with two, 5-pin XLR connectors for DATA IN and DATA THRU (out)
applications. DATA IN requires a 5-pin, female XLR connector and DATA THRU requires a 5-pin,
male XLR connector. When purchasing or constructing data cables, it is important that not only the
correct cable type be used, but also quality cable to ensure a reliable DMX512 system. Your cabling
should meet the following USITT DMX specification requirements:
• Suitable for use with EIA485 (RS485) operation at 250k baud.
• Characteristic impedance 85-150 ohms, nominally 120 ohms.
• Low capacitance.
• Two twisted pairs.
• Foil and braid shielded.
• 24 AWG min. gauge for runs up to 1000 feet (300m).
• 22 AWG min. gauge for runs up to 1640 feet (500m).
Note: Microphone type cables and other general purpose, two-core audio or signal cables are not
suitable for use with DMX512.
Refer to the USITT Recommended Practice for DMX512 guide for additional information regarding
DMX512 systems. How to obtain a copy is detailed in
