b. DMX512 Connections
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 VDP250SC6/3. Multiple VDP250SC6/3s can be linked through serial linking. The linking cable
should be a two-core screened cable with XLR input and output connectors.
c. DMX512 Chain with Termination
d. 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 starts to "listen" to the DMX controller. Enter the correct
number and read it from the display located on the base of the VDP250SC6/3.
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 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 6-channel VDP250SC6/3, you will have to set the start address of the first unit to 1, the second unit
to 7 (1 + 6), the third to 13 (7 + 6), and so on.
e. Function Selection
Use the display to control the several functions of the scanner. See table below:
f. Footswitch
Connect the optional foot switch (order code VDLFS) by inserting its plug into the input of the scanner.
VDP250SC6/3
Description
Gobo rotation
Dimmer / Strobe
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 to the left.
