5. Use
Switch the device on and off by means of the power plug. Do not operate the device continuously.
The device has 4 operation modes:
Single Mode
The device reacts to the music through the built-in microphone. All DIP switches should be placed in the OFF-
position.
Synchronous Mode
You can link several VDP250CG4's for synchronous movement to the music. The movements are steered by the
master unit.
Select a unique master device by placing DIP switch 10 in the ON-position. The built-in microphone of the master
device will now drive all slave units. Put DIP switch 11 in the ON-position to use the other devices as slaves and
connect master and slaves with the supplied DMX cable.
When in this mode, the built-in microphone of the master device controls all the interconnected devices. The beams
of all devices will change colours rhythmically and synchronously.
Program Mode
Put DIP switches 9 and 10 in the ON-position to activate the internal program.
DMX mode
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 "listens" to the digital commands from the DMX controller.
The start address/channel number is set by means of the DIP switches located at the back of the device.
You can set the same start address for a whole group of devices or enter an individual one for every device.
When using one single 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 VDP250CG4, a 4-channel device, you will have to set the start address of the first unit to 1, the
second unit to 5 (1 + 4), the third unit to 9 (5 + 4), and so on. The DMX start address is defined by the first 9 DIP
switches. The encoding is binary: DIP switch 1 has value 1, switch 2 has value 2, switch 3 is 4, switch 4 is 8, etc.
For example, if the start address were 95, the settings would be 111110100 (1+2+4+8+16+0+64+0+0=95).
The last DIP switch (10) is a selector. In the ON position, the device is music-controlled by means of the built-in
microphone. In the OFF position, the device is DMX-controlled.
The LED next to the DIP switches indicates the status of the DMX signal: if it's flashing there's a DMX signal; if it's off
there's no DMX signal.
Channel configuration
CHANNEL 1: 14 colours + white
CHANNEL 2: 14 gobos + white
CHANNEL 3: strobe
CHANNEL 4: dimming 0-100%
It is possible to link multiple units for synchronous operation by means of the enclosed DMX cable.
