c. Master – Slave mode
• This mode allows the user to link up to 32 units.
• In this mode one item will act as the controlling unit (master) and the others (slave) will react to it simultaneously.
• Daisy chain your units via the standard XLR cables in the following configuration: "OUT" from the master unit to
"IN" of the first slave unit, "OUT" from that slave unit to "IN" of the next slave unit, etc.
• The master unit can work under Auto Mode or Music Mode to control its slave units.
o Auto mode: Set DIP switch pin 10 and 11 to ON, all others to OFF.
o Music mode: Set DIP switch pin 11 to ON, all others to OFF.
• To set the slave units: set DIP switch pin 1 to ON, all others to OFF.
d. DMX Mode
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 VDP201GLD. Multiple VDP201GLDs can be linked through serial linking. The linking cable
should be two core, screened cable with XLR input and output connectors.
e. DMX-512 Chain with termination
f. 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 VDP201GLD.
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 6-channel VDP201GLD, you will have to set the start address of the first unit to 1, the second unit
to 7 (1 + 6), the third to 13 (7 + 6), and so on.
The DMX start address of the device is defined by the first 9 DIP switches. The encoding is binary: DIP switch 1 has
value 1, DIP switch 2 is 2, DIP switch 3 is 4, DIP switch 4 is 8, etc.
For example if the start address should be 95 the settings would be (for the first 9 switches): 111110100 (1 + 2 + 4 +
8 + 16 + 0 + 64 + 0 + 0 = 95).
The LED next to the DIP switches indicates the status of the DMX signal.
LED flashing = DMX signal present / LED off = no input DMX signal
• DMX operation gives the user the freedom to create his/her own programs tailored to their individual needs.
• To run this unit in DMX mode, connect the unit to any standard DMX controller via XLR connectors
• Set the DMX start address by means of DIP switch pins 1 to 9, all others to OFF
• Select your desired pattern by means of your DMX controller
VDP201GLD
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.
