USER MANUAL
DMX fixtures are designed to receive data though a serial Daisy Chain. A Daisy Chain connection is
where the DATA OUT of one fixture connects to the DATA IN of the next fiture.The order in which
the fixtures are connected is not important and has no effect on how a controller communicates to
each fixture. Use an order that provides for the easiest and most direct cabling .Connect fixtures
using shielded two conductor twisted pair cable with three pin XLR male to female connectors, The
shield connection is pin 1, while pin 2 is Data Negative (S-)and pin 3 is Data positive(S+)

Caution: At the last fixture, the DMX-cable has to be terminated with a terminator. Solder
a 120
resistor between Signal (-) and Signal (+) into a 3-pin XLR-plug and plug it in the
DMX-output of the last fixture.
I
n the Controller mode, at the last fixture in the chain, the DMX output has to be connected with a DMX
terminator. This prevents electrical noise from disturbing and corrupting the DMX control signals.
The DMX terminator is simply an XLR connector with a 120W (ohm) resistor connected across pins 2
and 3, which is then plugged into the output socket on the last projector in the chain. The connections
are illustrated below.
Occupation of the XLR-connection:

If you wish to connect DMX-controllers with other XLR-outputs, you need to use adapter-cables.
