DMX512 Chain with Termination
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
Ω
resistor between pins 2 and 3, which is then plugged into the XLR output
socket of the last device in the chain.
Please see illustrations.

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
VDPLP46B
.
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
VDPLP46B
s 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 4-channel
VDPLP46B
, you will have to set the start address of the first
VDPLP46B
to
1, the second
VDPLP46B
to 5 (1 + 4), the third to 9 (5 + 4) and so on.
