Data Cable (DMX Cable) Requirements:
Your fixture and your controller require a standard 3-pin XLR connector for data input and data output
(Figure 1). If you are making your own cables, be sure to use standard two conductor shielded cable
(This cable may be purchased at almost all pro sound and lighting stores). Your cables should be made
with a male and female XLR connector on either end of the cable. Also remember that DMX cable must
be daisy chained and can not be “Y”ed or split.
Notice: Do not use the ground lug on the XLR connec-
tor. Do not connect the cable’s shield conductor to the
ground lug or allow the shield conductor to come in con-
tact with the XLR’s outer casing. Grounding the shield
could cause a short circuit and erratic behavior.
Special Note:
For excessive cable runs totaling 100ft. or more, we recommend using a terminator
