7 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 light effect panel is equipped with 27 DMX
control channels. However, if required, it can be con-
trolled via 24, 15, 9, or 6 channels only. The functions
and the DMX values can be found on page 18.

7.1 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 (8) to the DMX output of the
light controller.
2) Connect the DMX output (7) to the DMX input of the
following light effect unit; connect its output again to
the input of the following 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").

7.2 Adjusting the number of DMX channels

To be able to operate the light effect panel with a light
controller, the DMX start address (
the number of DMX channels must be adjusted. The
number of DMX channels depends on the functions
required and possibly also on the number of the con-
trol channels available. Chapter 10.1, page 18, shows
information about the functions which are possible for
the operation with the following number of channels: 6,
9, 15, 24, and 27. Select the number of DMX channels
accordingly:

1) Press button MENU (11) so many times until the
display (16) shows
sure that the next button is pressed within 8 se-
conds, otherwise the adjusting process will end.
2) Press button ENTER (13). The number of DMX
channels is shown in a flashing way.
3) Use button DOWN or UP (12) to adjust the number
of DMX channels and memorize it with button
ENTER. reappears on the display. After 8 sec-
onds the light effect panel returns to the previous
function mode.

7.3 Adjusting the start address

To be able to operate the light effect panel with a light
controller, adjust the DMX start address for the first
DMX channel. If e. g. address 17 on the controller is
provided for controlling the function of the first DMX
channel, adjust the start address 17 on the RGBL-
82DMX. The other functions of the light effect panel
are then automatically assigned to the following
addresses. An example with the start address 17 is
shown below:
Number of Assigned
DMX channels DMX addresses
6 17 – 22
9 17 – 25
15 17 – 31
24 17 – 40
27 17 – 43

7.3.1 Automatic address adjustment

This method is useful when several RGBL-82DMX
units are used and the first light effect panel is to
receive the start address 1:
1) Connect all RGBL-82DMX units via the connections
DMX INPUT (8) and DMX OUTPUT (7) with each
other ( chapter 7.1) and switch them on. Adjust
the number of DMX channels on all RGBL-82DMX
units ( chapter 7.2).
2) Press button MENU (11) on the first RGBL-82DMX
(which is directly connected to the light controller)
so many times until the display (16) shows
3) Make sure to press button ENTER (13) within
8 seconds, otherwise the adjusting process will
end.
After pressing button ENTER, all LEDs of the light
effect panel light up and the indication
Then the LEDs will go out and the display stops flash-
ing. After another 8 seconds the light effect panel
returns to the previous operating mode.
The start address of the first light effect panel is now
adjusted to 1. The start addresses of the following
