5. INSTALLATION AND CONNECTIONS
Switch off the DMX controller prior to connecting any units or to changing any existing connections.
Fig. 5.1 Example for connection
Installation
Install the unit on a plane surface or in your rack. When choosing the installation spot make sure that there is
enough space around the unit for ventilation or that heated air from the rack can be passed on to improve
heat radiation. Steady overheating will damage the unit.
DMX512 Connection
Use a DMX cable and 3-pin XLR plugs and connectors in order to connect the controller to the DMX chain. If
you wish to connect fixtures with other XLR outputs, you need to use adapter cables.
Occupation of the XLR connection:
1
Prior to connecting light effect units, determine the signal polarity required by the DMX inputs and adjust
the polarity with the sliding switch accordingly. Set the switch to the left position for EUROLITE devices.
2
Connect the DMX output of the controller to the DMX input of the first light effect unit.
3
Connect the DMX output of the first fixture in the DMX chain to the DMX input of the next fixture. Always
connect one output to the input of the next fixture until all fixtures are connected.
4
At the last fixture, the DMX cable has to be terminated with a terminator. For this solder a 120
Ω
resistor between Signal (–) and Signal (+) into a 3-pin XLR plug and plug it in the DMX output of the last
fixture.
5
If the cable length exceeds 300 m or the number of DMX devices is greater than 32, it is recommended
to insert a DMX level amplifier to ensure proper data transmission.
Sound Control
For sound-controlled run of for illumination scenes in a memory bank or a chase it is possible to connect an
audio unit with line output (e.g. CD player, mixer) to the jack AUDIO INPUT (sensitivity 0.1-1 V). When
connecting the audio unit to the jack, the internal microphone is switched off.
