DMX Set Up
DMX-512: DMX is short for Digital Multiplex. This is a universal protocol used as a
form of communication between intelligent fixtures and controllers. A DMX
controller sends DMX data instructions from the controller 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 be linked together and operate from a single controller, as long as
all fixtures and the controller are DMX compliant. To ensure proper DMX data
transmission, when using several DMX fixtures try to use the shortest cable path
possible. The order in which 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 a DMX line, at the beginning, at the end, or
anywhere in the middle. When a fixture is assigned a DMX address of 1, the DMX
controller knows to send DATA assigned to address 1 to that unit, no matter where
it is located in the DMX chain.
Data Cable (DMX Cable) Requirements (For DMX Operation): The LED TOUR PAR 12
can be controlled via DMX-512 protocol. The LED TOUR PAR 18 has 4 DMX channel
modes. The DMX address is set on the back panel of the LED TOUR PAR 18. Your unit
and your DMX controller require a standard 3-pin XLR connector for data input and
data output (Figure 1). We recommend Accu-Cable DMX cables. If you are making
Your own cables, be sure to use standard 110-120 Ohm shielded cable (This cable
may
be purchased at almost all pro lighting stores). Your cables
should be made with a male and female XLR connector on
either end of the cable. Also remember that DMX cable
must be daisy chained and cannot be split.
Notice: Be sure to follow figures two and three when making your own cables. Do
not use the ground lug on the XLR connector. Do not connect the cable's shield
conductor to the ground lug or allow the shield conductor to come in contact with
the XLR's outer casing. Grounding the shield could cause a short circuit and erratic
behaviour.
