5. UNDERSTANDING DMX
DMX-512: DMX is short for Digital Multiplex. This is a universal protocol used by most
lighting and controller manufactures as a form of communication between intelligent
fixtures and controllers. DMX allows all makes and models of different manufactures to be
linked together and operate from a single controller. This is possible as long as all the
fixtures and the controller are DMX compliant. A DMX controller sends the DMX data
instructions to the fixture allowing the user to control the different aspects of an intelligent
light. DMX data is sent out as serial data that travels from fixture to fixture via data “IN” and
data “OUT” XLR terminals located on the fixtures (most controllers will only have output
jacks).
DMX Linking: To ensure proper DMX data transmission always use proper DMX cables
and a terminator. When using several DMX fixtures try to use the shortest cable path
possible. Never split a DMX line with a “Y” style connector. The order in which the fixtures
are connected in a DMX line does not influence the DMX addressing. For example; a
fixture assigned a DMX address of 1 may be placed anywhere in the DMX chain, at the
beginning, at the end, or anywhere in the middle. The DMX controller knows to send data
assigned to address 1 to that fixture no matter where it is located in the DMX chain. The
Power Spot 575IE II™ can be controlled via DMX-512 protocol. The Power Spot 575IE II™
is a 16-channel DMX fixture. The DMX address is set electronically using the controls on
the LCD menu.
Data Cable (DMX Cable) Requirements (For DMX and Master/Slave Operation): Your
fixture and your DMX controller require a standard 3-pin XLR connector for data input and
data output (the figure on the next page is of a 3-Pin XLR connector). If you are making
your own cables, be sure to use two conductor shielded digital DMX cable rated at 120
ohms; this cable is designed for DMX transmission and may be purchased from your
Elation dealer or at most professional lighting retailers. Your cables should be made with a
male and female XLR connector on either end of the cable. Also, remember that a DMX
line must be daisy chained and cannot be split, unless using an approved DMX splitter such
as the Elation Opto Branch 4™ or DMX Branch/4™.
