Data Cabling

To link fixtures 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.
D M X D a t a C a b l e
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:
C a b l e C o n n e c t o r s
Cabling must have a male XLR connector on one end and a female XLR connector on the other end.

CAUTION Do not allow contact between the common and the fixture's chassis ground.
Grounding the common can cause a ground loop and your fixture to perform
erratically. Test cables with OHM meter to verify correct polarity and to make
sure the pins are not grounded or shorted to the shield or each other.
