CW-12 System™ voltage is
between 100v ~ 240v. Be sure to only use the included I.E.C. power
cable supplied with the unit, this cable matches the voltage and cur-
rent requirements of the unit.
DMX-512:
DMX is short for Digital Multiplex. This is a universal pro-
tocol used by most lighting and controller manufactures as a form of
communication between intelligent fixtures and controllers.
A DMX
controller sends DMX data instructions from the controller to the fix-
ture. 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. Therefore, the first fixture controlled
by the controller could be the last fixture in the chain. 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 CW-12 System™ can be controlled via DMX-512 pro-
tocol. The CW-12 System™ can be a 3 channel DMX system or 5
Channel DMX system. The DMX address is set electronically using
the buttons on the top of the DCW 4™ . Your unit and your DMX con-
troller require a standard 3-pin XLR connector for
data input and data output (Figure 1). If you are
making your own cables, be sure to use standard
two conductor 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
Figure 1
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 con-
nect 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.

to connect a DMX terminal, (Resistance

and PIN 3 (DMX +) of the last fixture.

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 90-120 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.
