Orbitron™
Linking
Master/Slave Linking:
For a more dramatic effect, link several Orbitron™ together. Your
fi xture comes with built-in programs. These programs are designed
to work with up to 4 units when daisy-chained together in a master-
slave confi guration. Any unit can function as either a “Master Unit” or
a “Slave Unit.” Link the units together using standard DMX cable as
described on pages 5 and 6.

Optional MINI/C blackout controller
Optional MINI/C:
The optional MINI/C controller
allows all units linked together
to blackout. This unit will only
blackout the fi xtures and will
not change or select different
programs.

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 ZDMX/T) will decrease the possibilities of 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.

Notice:
Be sure to follow fi gure three when making your own cables.
Do not use the ground lug on the XLR connector. Do not connect the
cable’s shield conductor to the ground lug or allow the shield conduc-
tor to come in contact with the XLR’s outer casing. Grounding the
shield could cause a short circuit and erratic behavior.
5-Pin XLR DMX Connectors:
Some manufactures use 5-pin XLR
connectors for DATA transmission in place of 3-pin. 5-pin XLR fi xtures
may be implemented in a 3-pin XLR DMX line. When inserting stan-
dard 5-pin XLR connectors 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.
