DMX Linking:
• DMX is a language allowing all makes and models of different manufactures to be linked together
and operate from a single controller, as long as all fixtures and the controller are DMX compliant.
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 to 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 operation):
• The Slimline 229 can be controlled via DMX-512 protocol. The DMX address is set on the back of
the unit. Your unit and your DMX controller require a standard 3-pin XLR connector for data input/
output (figure 1).
Also remember that DMX cable must be daisy chained and cannot be split.
Notice:
• Be sure to follow figures 2 & 3 when making your own cables. Do not connect 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 behaviour.
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 behaviour.
Using a cable terminator (part number CABL90) will decrease the possibilities of erratic
behaviour.
5-Pin XLR DMX Connectors:
• Some manufactures use 5-pin XLR 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 standard 5-pin
XLR connectors in to a 3-pin line a cable adaptor must be used. The Chart below details the
correct cable conversion.

Termination reduces signal transmission problems
and interferance. 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.
