5. Use
DMX-512 control 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 VDP150CC2. You can chain multiple VDP150CC2's together through serial linking. The cable
needed is a two core, screened cable with XLR input and output connectors. Please refer to the diagram below.
DMX-512 connection with DMX termination
For installations where the DMX cable has to run a long distance or is in an electrically noisy environment, such as in
a discotheque, it is recommended to use a DMX terminator. This helps in preventing corruption of the digital control
signal by electrical noise. The DMX terminator is simply an XLR plug with a 120 Ω resistor connected between pins 2
and 3, which is then plugged into the output XLR socket of the last fixture in the chain. Please see illustrations below.
Projector DMX start address selection
All DMX-controlled devices need a digital start address so that the correct device responds to the signals. This digital
start address is the channel number from which the device "listens" to the digital commands from the DMX controller.
The start address/channel number is set by means of the DIP switches located at the back of the device.
You can set the same start address for a whole group of devices or enter an individual one for every device.
When using one single address, all the units 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 VDP150CC2, a 1 channel device, you will have to set the start address of the first unit to 1, the
second unit to 2 (1 + 1), the third unit to 3 (2 + 1), and so on. The DMX start address is defined by the DIP switches.
The encoding is binary: DIP switch 1 has value 1, switch 2 has value 2, switch 3 is 4, switch 4 is 8, etc.
For example, if the start address were 95, the settings would be 111110100 (1+2+4+8+16+0+64+0+0=95).
