You should test each cable with a voltage/ohm meter (VOM) to verify correct polarity
and to make sure that the negative and positive pins are not grounded or shorted to
the shield or to each other.
Caution: Do not connect anything to the ground lug on the XLR
connectors. Do not connect or allow contact between the
common (cable shield) and the fixture’s chassis ground.
Grounding the common could cause a ground loop and/or
erratic behavior.
Setting up the Link
To link one or more fixtures to a controller and/or to each other, follow the steps
below:
1. Connect a male XLR cable connector (with attached data cable) to the controller’s
Data Out connector.
If you plan to control your fixtures in stand-alone mode (without a controller),
connect a male XLR cable connector with attached data cable to the 3-pin or 5-
pin Data Out connector on the fixture addressed at DMX start channel 1 or fixture
number 1.
