8 DMX Control

DMX (Digital Multiplex) allows for digital
control of multiple DMX units by means of a
common control line . For operation by means
of a DMX light controller (e . g . DMX-1440 or
DMX-510USB), the LED spotlight is equipped
with 8 DMX control channels . However, it can
also be controlled by 5, 4 or 1 channel only,
if required . The functions of the channels and
the corresponding DMX values can be found in
chapter 10 .1 .

8.1 DMX connection

For DMX connection, 3-pole XLR connections
with the following pin configuration are avail-
able:
pin 1 = ground, 2 = DMX−, 3 = DMX+
For the connection, special cables for DMX
signal transmission (e . g . cables of the CDMXN
series) should be used . For cable lengths
exceeding 150 m, the insertion of a DMX
level matching amplifier (e . g . SR-103DMX) is
recommended .
1) Connect the input DMX IN (4) to the DMX
output of the light controller .
2) Connect the output DMX OUT (10) to the
DMX input of the second DMX unit . Connect
the output of the second DMX unit to the
input of the third unit, etc . until all DMX-con-
trolled units are connected in a chain .
3) To prevent interference in signal transmis-
sion: For long cables or for a great number
of units connected in series, terminate the
DMX output of the last DMX unit in the chain
with a 120 Ω resistor (> 0 .3 W): Connect an
appropriate terminating plug (e . g . DLT-123)
to the DMX output jack .

8.2 Setting the number of DMX channels

To operate the PARL-12RGBW by means of
a light controller, set the DMX start address
☞
( chapter 8 .3) and the number of DMX chan-
nels . The number of DMX channels depends on
the functions required and, if applicable, also on
18
the number of the control channels available at
the light controller . Please refer to chapter 10 .1
for the functions available and then select the
appropriate number:
1) Call up the menu item
indicate the current setting:
... = 1 ... 8 channels
2) Use the button UP or DOWN to set the num-
ber of channels, and then press ENTER to
save the setting .

8.3 Setting the start address

For separate control of the DMX units connected
to the light controller, each unit requires a start
address of its own . Example: If the first DMX
channel of the PARL-12RGBW is to be controlled
by DMX address 17, set the start address on the
PARL-12RGBW to 17 . The other DMX channels
of the PARL-12RGBW will then be automatically
assigned to the subsequent addresses .
Example for start address 17:
Number Addresses
of DMX for the
channels PARL-12RGBW
1 17
4 17 – 20
5 17 – 21
8 17 – 24

DMX address assignment of the PARL-12RGBW for
start address 17
Set the start address either by means of the
remote control:
Press the button DMX and then use the number
buttons to enter the 3-digit address (for example
for the address 17, press the following buttons:
DMX, 0, 1, 7)
or by means of the menu item
After that, the PARL-12RGBW can be operated
by means of the light controller .
Note: A dot will flash on the display when a DMX
signal is available at the DMX input (4) . As long as a
DMX signal is being received, it will not be possible to
continue operation by means of the infrared remote
control .
