Technical Specifications - HQ Power VDPL303WQD Notice D'emploi

DMX512 Chain with Termination
DMX512 Start Address
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 VDPL303WQD.
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 VDPL303WQDs 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 2-channel VDPL303WQD, you will have to set the start address of the first
VDPL303WQD to 1, the second VDPL303WQD to 3 (1 + 2), the third to 5 (3 + 2) and so on.

VDPL303WQD
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.
