• Overhead mounting requires extensive experience:
calculating workload limits, determining the
installation material to be used... Have the material
and the device itself checked regularly. Do not
attempt to install the device yourself if you lack
these qualifications as improper installation may
result in injuries.
• Adjust the desired inclination angle via the
mounting bracket and tighten the bracket screws.
• Make sure there is no flammable material within a 0.5m radius of the device.
• Have a qualified electrician carry out the electric connection.
• Connect the device to the mains with the power plug. Do not connect it to a dimming pack.
• The installation has to be approved by an expert before the device is taken into service.
h. Fuse Replacement
The fuse of your VDPLW2400 may be replaced as illustrated.
Caution: Always replace the fuse with a fuse of the same type
and rating. Disconnect from the mains before replacing.
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
VDPLW2400. Multiple VDPLW2400s 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
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 VDPLW2400.
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.
VDPLW2400
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.
