Data Cabling
To link products together you must obtain data cables. You can purchase CHAUVET®
certified DMX cables directly from a dealer/distributor or construct your own cable. If you
choose to create your own cable please use data-grade cables that can carry a high
quality signal and are less prone to electromagnetic interference.
DM X Data Cable
Use a Belden© 9841 or equivalent cable which meets the specifications for EIA RS-485
applications. Standard microphone cables cannot transmit DMX data reliably over long
distances. The cable will have the following characteristics:

Cable Connectors
Cabling must have a male XLR connector on one end and a female XLR connector on the
other end.

5-pin DMX connector configuration
Termination reduces signal errors. To
avoid signal transmission problems and
interference, it is always advisable to
connect a DMX signal terminator.
Do not allow contact between the common and the product's chassis ground.
Grounding the common can cause a ground loop, and your product may perform
erratically. Test cables with an ohm meter to verify correct polarity and to make
sure the pins are not grounded or shorted to the shield or each other.
