20D M X S E T U PDMX-512: DMX is short for Digital Multiplex. This is a universal protocol used as a form of commu-nication between intelligent fixtures and controllers. A DMX controller sends DMX data instructionsfrom the controller to the fixture. DMX data is sent as serial data that travels from fixture to fixture viathe DATA “IN” and DATA “OUT” XLR terminals located on all DMX fixtures (most controllers only havea DATA “OUT” terminal).DMX Linking: DMX is a language allowing all makes and models of different manufacturers to belinked together and operate from a single controller, as long as all fixtures and the controller areDMX compliant. To ensure proper DMX data transmission, try to use the shortest cable path possiblewhen linking several DMX fixtures. The order in which fixtures are connected in a DMX line does notinfluence the DMX addressing. For example, a fixture assigned a DMX address of 1 may be placedanywhere in a DMX line: at the beginning, at the end, or anywhere in the middle. When a fixture isassigned a DMX address of 1, the DMX controller knows to send DATA assigned to address 1 to thatunit, no matter where it is located in the DMX chain.Data Cable (DMX Cable) Requirements (For DMX Operation): This unit can be controlled via DMX-512 protocol. The DMX address is set on the rear panel of the unit. Your unit and your DMX controllerrequire a standard 5-pin XLR connector for data input and data output. We recommend Accu-CableDMX cables. If you are making your own cables, be sure to use standard 110-120 Ohm shieldedcable (This cable may be purchased at almost all pro lighting stores). Your cables should be madewith a male XLR connector at one end and a female XLR connector at the other. Also remember thatDMX cable must be daisy chained and cannot be split.Notice: Be sure to follow fthe illustration below when making your own cables. Do not use the groundlug on the XLR connector. Do not connect the cable’s shield conductor to the ground lug or allow theshield conductor to come in contact with the XLR’s outer casing. Grounding the shield could cause ashort circuit and erratic behavior.
