b) DMX512 Connection
Connect an XLR cable to the female 3-pin XLR output of your
controller and the other side to the male 3-pin XLR input of the
VDPLW1252. Multiple VDPLW1252s can be linked through serial
linking. The linking cable should be a two-core screened cable with
XLR input and output connectors.
c) DMX512 Chain with Termination
d) Projector DMX Start Address Selection
All DMX-controlled devices need a digital start address so that the correct device responds to the signals. This start
address is the channel number from which the device starts to "listen" to the DMX controller. Enter the correct
number and read it from the display located on the base of the VDPLW1252.
You can use the same starting address for a whole group of devices or enter an individual one for every device.
When all devices have the same address, all the VDPLW1252s will "listen" to the control signal on one particular
channel. In other words: changing the settings of one channel will affect all devices simultaneously. If you set
different addresses, each device will "listen" to a separate channel number. Changing the settings of one channel will
only affect the device in question.
In the case of the 12-channel VDPLW1252, you will have to set the start address of the first VDPLW1252 to 1, the
second VDPLW1252 to 13 (1 + 12), the third to 25 (13 + 12) and so on.

VDPLW1252
A DMX terminator is recommended for installations where the DMX cable has to run a
long distance or is in an electrically noisy environment (e.g. discos). The terminator
prevents corruption of the digital control signal by electrical noise. The DMX terminator is
simply an XLR plug with a 120 resistor between pins 2 and 3, which is then plugged into
the XLR output socket of the last device in the chain.
