Dmx Setup - ADJ VIZI CMY300 User Manual

D M X S E T U P
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 VIZI
CMY300 can be controlled via DMX-512 protocol. The DMX address is set on
the front panel of the VIZI CMY300. Your unit and your DMX controller require a
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 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 the figures below when making your own cables. Do not use the ground lug
on the XLR connector. Do not connect the shield of the cable conductor to the ground lug, or allow the
shield conductor to come in contact with the outer casing of the XLR. 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 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.
