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 AB L E CO N N ECT O R S
Cabling must have a male XLR connector on one end and a female XLR connector on the other end.

Do not allow contact between the common and the fixture's chassis ground.
Grounding the common can cause a ground loop, and your fixture 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.
If you use a controller with a 5 pin DMX output connector, you will need to use a 5
pin to 3 pin adapter. CHAUVET Model No: DMX5M, or DMX5F.
