5.4 Operation via a light controller
GB
For operation via a light controller with DMX512
protocol (e. g. DMX-1440 or DMX-510USB by "img
Stage Line"), the PARL-32DMX is equipped with
four DMX control channels. The functions of the
channels and the DMX values can be found in
chapter 7.1.
5.4.1 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 recommended to insert a DMX level matching
amplifier (e. g. SR-103DMX by "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 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) To prevent interference in signal transmission,
for long cables or a great number of units con-
nected in series, terminate the DMX output of
the last DMX unit in the chain with a 120 Ω resis-
tor (> 0.3 W): Connect a corresponding termi-
nating plug (e. g. DLT-123 by "img Stage Line")
to the output jack.
5.4.2 Adjusting the start address
To be able to operate the spotlight with a light con-
troller, adjust the DMX start address for the first
DMX channel. If e. g. address 17 on the DMX con-
troller is provided for controlling the red LEDs,
adjust the start address 17 on the spotlight. Then
the other DMX functions of the spotlight are auto-
matically assigned to the following addresses (in
this example 18, 19 and 20). The address 21 could
be used in this example as the next possible start
address for the following DMX-controlled unit.

1) Press the button FUNC (2).
2) Select the function
DOWN and confirm with the button ENT. The
display (3) shows
DMX start address flashing.
3) Use the button UP or DOWN to adjust the
desired start address and confirm with the but-
ton ENT. The display stops flashing and the
spotlight is ready to receive control signals.
5.4.3 DMX control
To be able to operate the spotlight with the DMX
controller, the display must show and behind it the
start address. If not, make the steps described in
chapter 5.4.2 to adjust the start address. The
reception of control signals is indicated by a flash-
ing dot behind the first position on the display.
If the display shows
DMX control mode but no DMX control signal is
present at the jack DMX IN (5).
6 Cleaning the Unit
The plastic pane in front of the LEDs should be
cleaned at regular intervals from the outside,
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 mild detergent. Then
wipe the plastic pane dry.
For cleaning the other parts of the housing, only
use a soft, clean cloth. Never use any fluid; it may
leak into the unit and cause damage.
