4 Before Operation

4.1 Setting up
Set up the controller on a flat surface . Via holes
on the front panel, the controller can also be
installed (e . g . in a rack), if required .
4.2 Connecting the spotlights
The DMX interface of the controller is a 3-pole
XLR connector with the following pin config-
uration:
Pin 1 = ground, Pin 2 = DMX−, Pin 3 = DMX+
For connection, special cables for DMX signal
transmission are recommended (e . g . cables
from the CDMXN series) . For cable lengths ex-
ceeding 150 m or when controlling more than
32 units via a single DMX output, it is generally
recommended to insert a DMX level matching
amplifier (e . g . SR-103DMX) .
Note: It is even possible to connect more than four spot-
lights to the controller: Simply set their start addresses
and the individual spotlights will be assigned to one
of the four spotlight groups . The order of connection
is irrelevant .
1) Connect the control input of the first spot-
light to the output DMX OUT (14) of the
controller .
2) Connect the control output of the first
spotlight to the control input of the second
spotlight . Connect the output of the second
spotlight to the input of the third spotlight
etc . until all spotlights have been connected
in a chain .
3) To prevent interference in signal transmis-
sion, in case of long cables or a multitude
of spotlights connected in series, terminate
the control output of the last spotlight in
the chain with a 120 Ω resistor (> 0 .3 W):
Connect a corresponding terminating plug
(e . g . DLT-123) to the output jack .

4.3 Power supply
Connect the plug-in power supply unit to the
jack 9 – 12 V (13) first, then connect the power
supply unit to a mains socket (230 V/50 Hz) .
4.4 Presets
The presets will match the controller to the
characteristics of the spotlights . The spotlights
must be set to independent control or control in
groups . It is ideal to use spotlights of the same
type . Different types of spotlights can only be
used together if they offer the same number of
channels and the same channel functions .
4.4.1 Setting the number of DMX channels
There are spotlights with different numbers of
control channels . Many spotlights offer multi-
ple operating modes with different numbers
of channels .
1) Spotlights with multiple operating modes:
Select the operating mode which allows in-
dividual control of the primary colours and
which offers a separate channel for total
brightness and for a strobe effect, if available
☞
( manual of the spotlights) .
2) On the controller, set the number of channels
of the individual spotlight: While the control-
ler is still switched off, set the switches 2 – 4
(12) on its front according to the table below .

On the basis of the number of channels adjust-
ed, the controller will calculate the start address-
es for the spotlights 2 to 4 .
