Power Supply: Before plugging your unit in, be sure the source volt-
age in your area matches the required voltage for your American DJ®
Quick Scan.™ The American DJ® Quick Scan
™
is available in a 120v
and 220v version. Because line voltage may vary from venue to venue,
you should be sure your unit voltages matches the wall outlet voltage
before attempting to operate you fixture.
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 and Master/
Slave Operation): The Quick Scan™ can be controlled via DMX-
512 protocol. The Quick Scan™ is a one channel DMX unit. The DMX
address is set on the back panel of the Quick Scan.™ Your unit and
your DMX controller 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 pro 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 can not 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.

Termination reduces signal errors and
avoids signal transmission problems
and interference. It is always advisable
to connect a DMX terminal, (Resistance
120 Ohm 1/4 W) between PIN 2 (DMX-)
and PIN 3 (DMX +) of the last fixture.
