Test all DMX cables with an ohmmeter to verify their correct polarity and
to make sure that there are no short-circuits between any of the pins, or
between any pin and ground.
If the common wire (shield) touches the chassis ground, a ground loop
could form, which may cause the fixture to perform erratically.
If you use a DMX controller or fixture with a 5-pin XLR connector, you will
need to use a 5-pin to 3-pin adapter. The chart below details a proper cable
conversion.

Make sure that the fixtures with which you are working can operate in DMX
mode, not in a proprietary connection mode. Refer to the
to learn how to enable their respective DMX modes.
The procedure below illustrates a possible DMX connection method.
1. Connect the 3-pin XLR, male connector of the first DMX cable to the DMX
Output connector (3-pin, female) of the DMX controller.
2. Connect the 3-pin XLR, female connector of the first DMX cable coming
from the controller to the DMX Input connector (3-pin, male) of the first
DMX fixture.
3. Connect the 3-pin XLR, male connector of the second DMX cable to the
DMX Output connector (3-pin, female) of the first DMX fixture.
4. Connect the 3-pin XLR, female connector of the second DMX cable
coming from the first DMX fixture to the DMX Input connector of the
