VL1600 PROFILE
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
specifi cation 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.
The XLR 5-pin connectors should be wired as follows:

RECOMMENDED CABLE TYPES/MANUFACTURERS
These are only a few of the suitable cable types. Any quality EIA485, twisted pair, 120 ohm, shielded cable will
also work. Refer to
