DMX connector configuration 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.

The chart below details a proper cable conversion: Notes Icon 03 - 200x227.gif 3-PIN TO 5-PIN CONVERSION CHART Conductor 3-Pin Female (Output) 5-Pin Male (Input) Ground/Shield Pin 1 Pin 1 Data ( - ) signal Pin 2 Pin 2 Data ( + ) signal Pin 3 Pin 3 Not used Pin 4 Not used Pin 5 This drawing provides a general illustration of the DMX input/output panel of a lighting fixture. Universal DMX Controller Continue the link Setting up a DMX Serial Data Link 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. 4. OPERATING INSTRUCTIONS Configuring the Starting Address Each fixture requires a starting address from 1~512. A fixture requiring one or more channels for control begins to read the data on the channel indicated by the starting address. For example, a fixture that uses seven DMX channels and is addressed to start on DMX channel 100, will read data from channels: 100, 101, 102, 103, 104, 105 and 106. Choose the starting addresses for each fixture so that the channels used do not overlap. In addition, you should note the starting address selected for future reference. The LED PAR 38 Tri-B/C fixture uses seven or three DMX channels. If this is your first time using DMX, we recommend reading the “DMX Primer” section in the “Appendix”.
