7. DMX512 Connections
Connect an 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
VDPDP1-2 . Multiple VDPDP1-2 s can be linked through serial linking. The linking cable should be a two-
core screened cable with XLR input and output connectors.
8. 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 120
Ω
resistor between pins 2 and 3, which is then plugged into
the XLR output socket of the last device in the chain.
9. Projector DMX Start Address Selection
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
VDPDP1-2 .
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
VDPDP1-2 s 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 1-channel
VDPDP1-2 , you will have to set the start address of the first VDPDP1-2 to 1, the second
VDPDP1-2 to 2 (1 + 1), the third to 3 (2 + 1) and so on.
10. Cleaning and Maintenance
1. All screws should be tightened and free of corrosion.
2. The housing, visible parts, mounting supports and the installation location (e.g. ceiling, suspension, trussing)
should not be deformed, modified or tampered with e.g. do not drill extra holes in mounting supports, do not
change the location of the connections.
3. Moving mechanic parts must not show any signs of wear and tear.
4. The electric power supply cables must not show any damage. Have a qualified technician maintain the device.
5. Disconnect the device from the mains prior to maintenance activities.
6. Wipe the device regularly with a moist, lint-free cloth. Do not use alcohol or solvents.
7. There are no user-serviceable parts.
8. Contact your dealer for spare parts if necessary.
