•
Never stand directly below the device when it is being mounted, removed or serviced. Have a qualified technician
check the device once a year and once before you bring it into service.
•
Install the device in a location with few passers-by that is inaccessible to unauthorised persons.
•
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.
•
Connect the device to the mains with the power plug.
•
The installation has to be approved by an expert before the device is taken into service.
5. Use
The smoke machine is controlled by 1 DMX channel: CHANNEL 1 = output channel
a. DMX 512 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
VDP1500SSM
.
Multiple
VDP1500SSM
s can be linked through serial
linking. The linking cable should be two core,
screened cable with XLR input and output
connectors.
Please refer to the diagram at the right.
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 to the left.
c. Projector DMX start address selection
All DMX-controlled devices need a 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
VDP1500SSM
.
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 1-channel
VDP1500SSM
, the start address of the first unit is 1, the second unit is 2, the third is 3.
