Dmx Set Up - ADJ VIZI BSW 300 User Instructions

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 and Master/Slave Operation):
The Vizi BSW 300 can be controlled via DMX-512 protocol. The Vizi BSW 300
has 2 DMX channel modes; 17 channel mode, and 20 channel mode. The DMX
address is set electronically using the controls on the front panel of the unit.
Your unit and your DMX controller require a approved DMX-512 110 Ohm Data
cable 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 professional sound
and 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
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.
