voltage switch, which will auto sense the voltage when it is plugged
into the power source. With this switch there is no need to worry about
the correct power voltage, this unit can be plugged in anywhere.
DMX-512:
DMX is short for Digital Multiplex. This is a universal pro-
tocol 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 trav-
els from fixture to fixture via the DATA "IN" and DATA "OUT" XLR ter-
minals 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 sin-
gle controller, as long as all fixtures and the controller are DMX com-
pliant. 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 Dekker LED can be a 2 channel DMX unit or 8 channel DMX unit.
The DMX address is set electronically using the controls on the rear
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 rec-
ommend 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 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.

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.

fixtures may be implemented in a 3-pin DMX line. When inserting stan-
dard 5-pin data cables in to a 3-pin line a cable adaptor must be used,
these adaptors are readily available at most electric stores. The chart
below details a proper cable conversion.
