DMX-512: DMX is short for Digital Multiplex. This is a universal protocol used as a form of communi-
cation 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 manufacturers 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, to to use the shortest path possible when linking
several DMX fixtures. 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 32 Hex Panel IP/32 Hex Panel
IP Pearl can be controlled via DMX-512 protocol. The DMX address is set on the back panel of the 32
Hex Panel IP/32 Hex Panel IP Pearl, and the unit and DMX controller require a standard 5-pin XLR
connector for data input and data output. 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 XLR connector at one end
and a female XLR connector at the other. Also remember that DMX cable must be daisy chained and
cannot be split.
Special Note: Line Termination. When longer runs of cable are used, you may need to use a termi-
nator on the last unit to avoid erratic behavior. A terminator is a 110-120 ohm 1/4 watt resistor which is
connected between pins 2 and 3 of a male XLR connector (DATA + and DATA -). This unit is inserted
in the female XLR connector of the last unit in your daisy chain to terminate the line. Using a cable
terminator (ADJ part number Z-DMX/T) will decrease the possibilities of erratic behavior.
TO MAINTAIN IP65 RATING INTEGRITY AND PREVENT WATER FROM ENTERING THE FIX-
TURE, ALL CONNECTION RUBBER CAPS MUST BE SEALED WHEN NOT IN USE, AND ONLY
IP65 RATED POWER AND DATA CABLES SHOULD BE USED.
