OCCUPATION OF THE XLR-CONNECTION:
You can adjust the XLR polarity via the DMX polarity selector.
BUILDING A SERIAL DMX CHAIN:
connect the DMX output of the device with the DMX input of the nearest projector. Always
connect one output with the input of the next fixture until all fixtures are connected.
CAUTION:
For all installation, having long signal cables or in
the presence of electrical noise, for example a
discotheque, it is recommended practice to use a
DMX terminator: this assist in preventing
corruption of the digital control signal by external
noise. The DMX terminator is simply an XLR
connector with a 120 (Ohm) resistor connected
across pins 2 and 3, which is then plugged into the
DIGITAL THRU socket on the last projector in the
chain. The connection are illustrated on the right.
PROJECTOR ADDRESSING:
Please note that the DMX operator assigns the DMX starting addressed every 20 steps. You
have to address every projector to the respective starting address. Otherwise the channel
assignment. Will not be correct. All projectors with the same starting address work
synchronically.
