8.1
Power connections
Have a qualified electrician carry out the electric connection.
Connect the device to the mains with the power plug. All devices must be powered directly off a grounded
switched circuit.
Never connect the device to a rheostat or dimmer, even if the rheostat or dimmer channel is used solely for
0 % to 100 % switching.
The device has a power output to supply power to another device. When connecting several devices in a
daisy chain via this output, make sure that the total current does not exceed the power line’s nominal
current. Use power cables with an adequate section. If you do not use the power linking feature, be sure to
use the included screw-on cap to prevent any water from getting into the power cords.
The installation has to be approved by an expert before the device is taken into service.
Disconnect after use.
Power Linking
You can link up to 13 devices at 230 V (7 devices at
120 V). Never exceed this number. Power linking
cords can be purchased separately.
Data linking
The device works connected through a network switch (or crossover cable) to a controller or computer
(Windows®, Apple Macintosh® or Linux®) with Kling-Net/Art-Net compatible software installed.
Data Connection
With Kling-Net/Art-Net, the device uses an RJ45 data connection to link all data ports.
8.2
DMX linking
The device works with any DMX controller with a DMX serial connection.
DMX-512 Connection
When applicable, connect an XLR cable to the female XLR output of a controller (not incl.) and the other
side to the male XLR input of the device. Multiple devices can be linked through serial linking. The linking
cable should be a dual core, screened cable with XLR input and output connectors.
Maximum recommended serial data link distance is 500 meters (1640 ft). Maximum recommended number
of devices on a serial data link is 32 devices.
A DMX terminator is recommended for installations where the DMX cable has to run a long distance or is in
an electrically noisy environment (e.g. discos). The terminator prevents corruption of the digital control
signal by electrical noise. The DMX terminator is simply an XLR plug with a 120 Ω resistor between pins 2
and 3, which is then plugged into the XLR output socket of the last device in the chain.
