units are used.
Colour transition mode
– The LED of the button MODE will flash rapidly –
With the button FUNCTION, set the transition
speed for the colours to slow, medium or fast. A
music control will not be possible in this mode.
6 Operation via a Light Controller
For operation via a light controller with DMX512 proto-
col (e. g. DMX-1440 or DMX-510USB from "img Stage
Line"), the CPL-3DMX is equipped with four DMX con-
trol channels. The functions of the channels and the
DMX values can be found in chapter 7.1 on page 11.

6.1 DMX connection

For the DMX connection, the unit is provided with
3-pole XLR jacks of the following pin configuration:
Pin 1 = ground, 2 = DMX-, 3 = DMX+
For connection, special cables for high data flow
should be used. Standard microphone cables with
screening and a minimum cross section of 2 ×
0.22 mm 2 and with a capacity as low as possible can
only be recommended for a total cable length of up to
100 m. For cable lengths exceeding 150 m it is recom-
mended to insert a DMX level matching amplifier (e. g.
SR-103DMX from "img Stage Line").
1) Connect the DMX input (5) to the DMX output of the
light controller.
2) Connect the DMX output (6) to the DMX input of the
following CPL-3DMX unit or the following light effect
unit. Connect its output again to the input of the fol-
lowing unit, etc. until all light effect units have been
connected in a chain.
3) Terminate the DMX output of the last DMX unit in
the chain with a 120 Ω resistor (> 0.3 W): Solder the
resistor to the pins 2 and 3 of an XLR plug and con-
nect the plug to the DMX output or use a corre-
sponding terminating plug (e. g. DLT-123 from "img
Stage Line").

6.2 Adjusting the start address

For operating the CPL-3DMX with a light controller,
adjust the DMX start address for the first DMX chan-
nel. If e. g. address 17 on the controller is provided for
controlling the proportion of red, adjust the start
address 17 on the CPL-3DMX. The DMX channels
2 – 4 will then automatically be assigned to the three
following addresses (in this example 18 – 20). As the
next possible start address for the following DMX-con-
trolled unit, address 21 could be used in this example.
After adjusting the start address, the CPL-3DMX
can be operated via the DMX controller. Once DMX
signals are received, the red indicating LED (1) will
flash steadily.

6.2.1 Automatic address adjustment
This method is recommended when several CPL-3DMX
units are used and the first unit is to receive start
address 1:
1) On all CPL-3DMX units, set all DIP switches (2) to
the lower position (OFF)
Fig. 4 Automatic adjustment: all switches set to OFF
2) Interconnect all CPL-3DMX units via the DMX
INPUT (5) and the DMX OUTPUT (6) [
6.1] and switch them on.
3) On the first CPL-3DMX unit (directly connected to
the light controller), keep the button AUTO DMX
ADDRESS (3) pressed for five seconds until the
LEDs connected are extinguished.
After a while, the LEDs will light up again. The start
address of the first CPL-3DMX unit is now set to 1. The
start addresses of the following CPL-3DMX units are
respectively set to the next DMX address that is free:
nd
2 unit to address 5
3 rd unit to address 9
th
4 unit to address 13
th
5 unit to address 17, etc.
6.2.2. Manual address adjustment
The start address is adjusted as a binary number with
the DIP switches Nos. 1 – 9 (2). It will result by adding
the place values of the switches set to "ON". (Switch
No. 10 is without function.)
Examples of the start addresses 1, 6 and 104:
Fig. 5 Start address 1: switch No. 1 set to ON
Fig. 6 Start address 6: switches Nos. 3 and 2 set to ON
Fig. 7 Start address 104: switches Nos. 7, 6 and 4 set to ON
The easiest way is to start from the highest possible
place value and to add the smaller values until the start
address will result.
