4.3 Operation with a DMX controller
DMX is short for Digital Multiplex and means
digital control of multiple DMX units via a com-
mon control line. For operation via a DMX con-
troller (e. g. DMX-3216 or DMX-4840), the spot-
light is equipped with 13 DMX control channels.
However, it can, if required, also be controlled
via a smaller number of channels. Please refer to
chapter 4.3.5 for more information on channel
functions and DMX values.
4.3.1 Connection
For DMX signal transmission, special cables
should be used (e. g. CDMXN-…). For cable
lengths exceeding 150 m or for control of more
than 32 units via a single DMX output, it is gener-
ally recommended to insert a DMX level matching
amplifier (e. g. SR-103DMX).
1) Connect the input DMX IN to the DMX output
of the light controller or to the DMX output
of another DMX-controlled unit.
2) Connect the output DMX OUT to the DMX
input of the second DMX unit. Connect the
output of the second DMX unit to the input
of the third DMX unit etc. until all DMX-con-
trolled 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 DMX output
of the last DMX unit in the chain with a 120 Ω
resistor (> 0.3 W): Connect a corresponding
terminating plug (e. g. DLT-123) to the DMX
output jack.
4.3.2 Setting the number of DMX channels
To operate the spotlight with a light controller,
the DMX start address (
☞
chapter 4.3.3) and the
number of DMX channels must be set. The num-
ber of DMX channels depends on the functions
required and may also depend on the number
of control channels that are available at the light
controller. Please refer to fig. 2 and chapter 4.3.5
for more information on the functions that are
provided for the individual channel modes, and
select the number of DMX channels accordingly:
1) Press the button MENU repeatedly until the
display indicates .
2) Press the button ENTER. The display now in-
dicates the current setting:

3) Use the button UP or DOWN to select the
setting desired.
4.3.3 Setting the DMX start address
For separate control of all DMX units connected
to the light controller, each unit must have its
own start address. If the first DMX channel of the
spotlight is to be controlled by the light controller
via DMX address 17, for example, set the start
address on the spotlight to 17. All other DMX
channels of the spotlight will be automatically
assigned to the following addresses. The follow-
ing table is an example with the start address 17:
