ADJ Products, LLC - www.adj.com - Contour User Manual Page 6Contour DMX Set UpDMX-512: DMX is short for Digital Multiplex. This is a universal protocol used as a form of communicationbetween intelligent fixtures and controllers. A DMX controller sends DMX data instructions from thecontroller to the fixture. DMX data is sent as serial data that travels from fixture to fixture via the DATA“IN” and DATA “OUT” XLR terminals located on all DMX fixtures (most controllers only have a DATA“OUT” terminal).DMX Linking: DMX is a language allowing all makes and models of different manufactures to belinked together and operate from a single controller, as long as all fixtures and the controller are DMXcompliant. To ensure proper DMX data transmission, when using several DMX fixtures try to usethe shortest cable path possible. 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): The Contour canbe controlled via DMX-512 protocol and has 3 DMX channel modes. The DMXaddress is set on the rear panel. The Contour requires a standard 3-pin XLR connectorfor data input and data output (Figure 1), which are included on the included DMXcables. If you are making your own cables, be sure to use standard 110-120 Ohmshielded cable (This cable may be purchased at almost all pro lighting stores). Yourcables should be made with a male and female XLR connector on either end ofthe cable. Also remember that DMX cable must be daisy chained and cannot besplit. Figure 1Notice: Be sure to follow figures 2 and 3 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.DMX512 IN3-PIN XLRSOUNDREMOTECONTROLINPUTPOWERINPUT OUTPUT SOUNDREMOTECONTROLINPUTPOWERINPUT OUTPUT SOUNDDMX512DMX+,DMX-,COMMON123Termination reduces signal e rroavoids signal transmission prand interference.
