DMX512 Connection
Connect the provided 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 VDP130RGBLD11. Multiple VDP130RGBLD11s can be linked through serial
linking. The linking cable should be a two-core screened cable with XLR input and output connectors.
DMX512 Chain with Termination
DMX 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 VDP130RGBLD11.
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 VDP130RGBLD11s 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 11-channel VDP130RGBLD11, you will have to set the start address of the first
VDP130RGBLD11 to 1, the second VDP130RGBLD11 to 12 (1 + 11), the third to 23 (12 + 11) and so on.

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.
Please see illustrations.

Solution
Turn on the device
Plug the device into the mains
Check that the fuse is intact and serviceable
Check the presence of a proper connection between the control
and the device
Individually check all cables for continuity on all three pins
Check the polarity of the DMX cable
Check the DMX cables and control DMX selection switch if
present
Reassign the DMX address via the DIP switches; remove and
reinsert the power cable
