Power Supply:
Before plugging your unit in, be sure the source volt-
age in your area matches the required voltage for your American DJ

Jellydome.™ The American DJ

Jellydome™ 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.
Dip-switches in DMX mode: This unit uses dipswitches to assign a
DMX address. Each dipswitch represents a binary value.
Dipswitch 1 address equals 1
Dipswitch 2 address equals 2
Dipswitch 3 address equals 4
Dipswitch 4 address equals 8
Dipswitch 5 address equals 16
Dipswitch 6 address equals 32
Dipswitch 7 address equals 64
Dipswitch 8 address equals 128
Dipswitch 9 address equals 256
Dipswitch 10 - Some units omit dipswitch 10. When a unit does include

dipswitch 10 it is used for special functions.
Each dipswitch has a preset value. A specific DMX address is set by
combining the dipswitches that sum your desired value. For example:
To achieve a DMX address of 21, combine dipswitches 1, 3, and 5.
Sense dipswitch 1 has a value of 1, dipswitch 3 has a value of 4, and
dipswitch 5 has a value of 16, the combination of the create a DMX
value of 21.
Set DMX address 21:
Set DMX address 201:
Dipswitch # 1 = 1
Dipswitch # 1 = 1
Dipswitch # 3 = 4
Dipswitch # 4 = 8
Dipswitch # 5 = 16
Dipswitch # 7 = 64
= 21
Dipswitch # 8 = 128
= 201
Data Cable (DMX Cable) Requirements (For DMX and Master/
Slave Operation):
The Jellydome™ can be controlled via DMX-512
protocol. The American DJ
®
Jellydome™ is a three channel DMX unit.
The DMX address is set on the back panel of the Jellydome™. Your unit
and your DMX controller require a approved DMX-
512 110 Ohm Data cable for data input and data
output (Figure 1). We recommend 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
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.

Termination reduces signal errors and
avoids signal transmission problems

to connect a DMX terminal, (Resistance

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