4. Installation
a. Connecting the Device
1. Power supply: 220VAC / 50-60Hz
2. Fuse: 5 x 20mm F1A (order code: FF1N)
3. Signal input: XLR connector connected with a DMX512 control panel.
4. Signal output: XLR connector connected with next spot.
5. DMX-address switches: Stand-alone function or DMX setting.
6. Microphone for sound activation
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 VDPLS1025. Multiple VDPLS1025s can be linked through serial linking. The linking cable
should be two core, screened cable with XLR input and output connectors.
Caution: At the last fixture, the DMX cable has to be terminated with a terminator.
Only use a stereo shielded cable and 3-pin XLR plugs and connectors in order to connect the controller with the
fixture or one fixture with another.
c. Occupation of the XLR connector
d. DMX-512 Chain with Termination
e. 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 VDPLS1025.
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 4-channel VDPLS1025, you will have to set the start address of the first unit to 1, the second unit
to 5 (1 + 4), the third to 9 (5 + 4), and so on.
VDPLS1025_v2
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.
