Notice:
Be sure to follow figure 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.

Special Note: Line Termination.
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

5-Pin XLR DMX Connectors:
connectors for DATA transmission in place of 3-pin. 5-pin XLR fixtures
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.

Master/Slave Linking:
For a more dramatic effect, link several MB DMX™ together. Your
fixture comes with built-in programs. These programs are designed
to work with up to 4 units when daisy-chained together in a master-
POWER
slave configuration. 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 6 and 7.
