5. DMX512 Connections
a. 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
VDPLW1308BI
. Multiple
VDPLW1308BI
s can be linked through
serial linking. The linking cable should be a two-core screened
cable with XLR input and output connectors. Please refer to the
diagram.
b. DMX-512 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.
Please see illustrations.
c. 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
VDPLW1308BI
.
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.
6. Cleaning and Maintenance
1. All screws should be tightened and free of corrosion.
2. The housing, the lenses, the 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. Mechanically moving 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, apart from the fuse (see “
Installation
”).
8. Contact your dealer for spare parts if necessary.
