CAUTION 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.
3- PIN TO 5 - PIN CONVERSION CH ART
Note! If you use a controller with a 5 pin DMX output connector, you will need to use a 5 pin to 3 pin adapter. The chart below details a proper cable conversion:

Setting up a DMX Serial Data Link
Universal DMX Controller
1.Connect the (male) 3 pin connector side of the DMX cable to the output (female) 3 pin connector of the controller.
2.Connect the end of the cable coming from the controller which will have a (female) 3 pin connector to the input connector of the next fixture consisting of a (male) 3 pin connector.
3.Then, proceed to connect from the output as stated above to the input of the following fixture and so on.
