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 VDPLW2401. Multiple VDPLW2401s 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

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.

Please see illustrations.

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 VDPLW2401.

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 VDPLW2401s 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.
