Data Cables

The VLX™ Wash 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 minimum gauge for runs up to 1000 feet (300m).
• 22 AWG minimum 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.
The XLR 5-pin connectors should be wired as follows:
