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
Focus Flex can be controlled via DMX-512 protocol. Your unit and your
DMX controller requires a 5-pin XLR connector for data input/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 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 behavior.
Special Note: Line Termination. When longer runs of cable are used, you may need to use a terminator
on the last unit to avoid erratic behavior. A terminator is a 110-120 ohm 1/4 watt resistor which is con-
nected 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.
