Dmx Channel - American DJ ScanTron User Instructions

ScanTron™
Power Supply:
Before plugging your unit in, be sure the source volt-
age in your area matches the required voltage for your American DJ
ScanTron.™ The American DJ
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 fi xture.
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 fi xtures 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.
Dip-switches in DMX mode: This unit uses dip switches to assign a
DMX address. Each dip switch represents a binary value.
Dip Switch 1 address equals 1
Dip Switch 2 address equals 2
Dip Switch 3 address equals 4
Dip Switch 4 address equals 8
Dip Switch 5 address equals 16
Dip Switch 6 address equals 32
Dip Switch 7 address equals 64
Dip Switch 8 address equals 128
Dip Switch 9 address equals 256
Dip Switch 10 - Some unit omit dip switch 10, when a unit does
included dip switch 10 it is usually used for special functions such as

Each dip switch has a preset value. A specific DMX address is set by
®
combining the dip switches that sum your desired value. For exam-
ple: To achieve a DMX address of 21, combine dip switches 1, 3, and
5. Sense dip switch 1 has a value of 1, dip switch 3 has a value of 4,
and dip switch 5 has a value of 16, the combination of the create a
DMX value of 21.

Data Cable (DMX Cable) Requirements (For DMX and Master/Slave
Operation): The ScanTron™ can be controlled via DMX-512 protocol.
The ScanTron™ is a fi ve channel DMX unit. The DMX address is set
on the bottom panel of the ScanTron. ™ 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 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 fi gures 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.
