DMX-512 Chain with Termination
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
VDPLW1028W.
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 VDPLW1028Ws 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 13-channel VDPLW1028W, you will have to set the start address of the first
VDPLW1028W to 1, the second VDPLW1028W to 14 (1 + 13), the third to 27 (14 + 13) and so
on.

holes in mounting supports, do not change the location of the connections.
3. Moving mechanic parts must not show any signs of wear and tear.
4. The electric power supply cables must not show any damage. Have a qualified technician

VDPLW1028W
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 120Ω resistor
between pins 2 and 3, which is then plugged into the XLR output socket of
the last device in the chain.
