6.4 Master / slave operation
GB
Several LED-380RGBW units may be intercon-
nected to control all further slave units via a master
unit. Connect the output DMX OUTPUT (7) of the
master unit via a 3-pole XLR cable to the input DMX
INPUT (6) of the first slave unit. Connect the output
DMX OUTPUT of the first slave unit to the input
DMX INPUT of the second slave unit etc., until all
units are connected in a chain.
Set the master unit to a "G" mode (
or a "C" mode (
units to the slave operation as follows: press the
button MODE (10) so many times until
shown on the display (9). Once control signals are
received from the master unit, the point behind the
letter will flash on the display.
7 DMX Control
For operation via a light controller with DMX512
protocol (e. g. DMX-1440 or DMX-510USB from
"img Stage Line") the light effect unit is equipped
with 7 DMX control channels, however, it can also
be operated with 4 DMX control channels. In the
7-channel mode the selection of the patterns for the
four LED groups is made separately, in the 4-chan-
nel mode a common pattern is selected for all four
LED groups. The functions of the channels and the
corresponding DMX values can be found in chapter
9.1.
7.1 Connection
As a DMX interface the unit is equipped with 3-pole
XLR connections with the following contact config-
uration:
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 recommended to insert a DMX level matching
amplifier (e. g. SR-103DMX from "img Stage Line").
1) Connect the DMX input (6) to the DMX output of
the light controller.
2) Connect the DMX output (7) to the DMX input of
the next light effect unit. Connect its output again
to the input of the following unit, etc. until all light
effect units are connected in a chain.
3) Terminate the DMX output of the last DMX unit of
the chain with a 120 Ω resistor (> 0.3 W): Con-
nect a corresponding terminating plug (e. g.
DLT-123 from "img Stage Line") to the jack.

7.2 Adjusting the number of the DMX
channels
Press the button FUNC (11) so many times until the
channel mode presently adjusted is shown on the
display (9):
(7-channel mode). Select the desired option with
the button UP or DOWN. Then press the button
MODE (10): The display shows the operating mode
again.

7.3 Adjusting the start address
For operating the unit with a light controller, adjust
is
the DMX start address for the first DMX channel.
The following DMX channels are then automatically
assigned to the following addresses (e. g. for start
address 5 in the 7-channel mode, the channels 2 to 7
are assigned to the addresses 6 to 11, address 12
would then be the next possible free start address
for the following DMX controlled unit).
Press the button MODE (10) so many times until
the display (9) shows the last address adjusted,
e. g.
UP or DOWN (12).
After adjusting the start address, the light effect
unit can be operated via the DMX controller. Once
DMX signals are received, the point behind the let-
ter will flash on the display.
8 Cleaning the Unit
The four lenses should be cleaned at regular inter-
vals, depending on impurities caused by dust,
smoke or other particles. Only this will ensure that
the light is radiated at maximum brightness. For
cleaning, disconnect the mains plug from the
socket. Only use a soft, clean cloth and a deter-
gent for glass.
For cleaning the other parts of the housing, only
use a soft, clean cloth. Never use any chemicals or
a fluid; it may leak into the unit and cause damage.
