Cable Connectors
Cables must have a male XLR connector on one end and a female XLR
connector on the other end. (Duh!)
CAUTION: Do not allow contact between the common and the
fi xture’s chassis ground. Grounding the common can cause a ground
loop, and your fi xture 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.
3-Pin??? 5-Pin??? Huh?!?
If you use a controller with a 5 pin DMX output connector, you will need to use a 5 pin to 3 pin adapter.
They are widely available over the internet and from specialty retailers. If you’d like to build your own,
the chart below details a proper cable conversion:

Take It To The Next Level: Setting Up DMX Control
Step 1: Connect the male connector of the
DMX cable to the female connector (output)
on the controller.
Step 2: Connect the female connector of
the DMX cable to the fi rst fi xture’s male
connector (input). Note: It doesn’t matter
which fi xture address is the fi rst one
connected. We recommend connecting the
fi xtures in terms of their proximity to the
controller, rather than connecting the lowest
fi xture number fi rst, and so on.
Step 3: Connect other fi xtures in the chain
from output to input as above. Place a DMX
terminator on the output of the fi nal fi xture
to ensure best communication.
