DMX Control

DMX is short for digital multiplex and allows digital
control of several DMX units via a common control
cable . For operation via a DMX light controller (e . g .
DMX-1440 or DMX-510USB from IMG STAGELINE)
the LED spotlight is provided with 8 DMX control
channels . If required, it can also be controlled via
6, 5, 4 or 3 channels only . The functions of the
channels and the corresponding DMX values can
be found in chapter 10 .1 .

8.1 Connection

As a DMX interface, 3-pole XLR connectors with the
following pin configuration are provided:
Pin 1 = ground, Pin 2 = DMX−, Pin 3 = DMX+
For DMX signal transmission, special cables are
recommended (e . g . cables of the CDMXN series
from IMG STAGELINE) . For cable lengths exceed-
ing 150 m or when controlling more than 32 units
via a single DMX output, it is generally recom-
mended to insert a DMX level matching amplifier
(e . g . SR-103DMX) .
1) Connect the control input DMX IN (6) to the
DMX output of the light controller .
2) Connect the control output DMX OUT (5)
to the control input DMX IN of the following
DMX- controlled unit; connect its output again
to the input of the following unit, etc . until all
DMX-controlled units have been connected in
a chain .
3) To prevent interference in signal transmission,
in case of long cables or a multitude of units
connected in series, terminate the control output
of the last DMX unit in the chain with a 120 Ω
resistor (> 0 .3 W): Connect a corresponding ter-
minating plug (e . g . DLT-123) to the output jack .
8.2 Setting the number of
DMX channels
The number of DMX channels depends on the re-
quired functions and may also depend on the num-
ber of control channels available on the light con-
troller . In the 8-channel mode, various internal show
programs are available . In addition, sub- addresses
allow individual control of up to 66 PARL-174DMX
spotlights via 8 DMX channels only . To select the
