Power Supply: Before plugging your unit in, be sure the source volt-

age in your area matches the required voltage for your American DJ®

Double Roller.™ The American DJ® Double Roller 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 Double Roller can be controlled via DMX-512 proto-

col. The Double Roller is a eight channel DMX unit. The DMX address

is set on the bottom panel of the Double Roller.™ Your unit and your

DMX controller require a standard 3-pin XLR con-

nector 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.

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.
