Velleman VDP7510S2 - Manual (Page 5)

VDP7510S2_v4 HQPOWER™ 5
The blinder automatically runs the built-in program. Brightness and speed can be adjusted
through the controls at the back: brightness (0 ~ 100%) and speed (80ms/step ~ 8s/step).
o
Audio Mode
The blinder reacts to the surrounding sound. Brightness and sound sensitivity can be adjusted
through the controls at the back.
o
Master/Slave Mode
Interconnect several blinders through the 3-pin XLR connection. Set the first blinder as master
device and set all other blinders as slave devices.
• DMX512 Connection
Connect an 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 VDP7510S2. Multiple VDP7510S2s can be linked through serial
linking. The linking cable should be a two-core screened cable with XLR input and output connectors.
• DMX512 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 120Ω 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.
• DMX Start Address Selection
All DMX-controlled devices need a digital 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
VDP7510S2.
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 VDP7510S2s 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 11channel VDP7510S2, you will have to set the start address of the first
VDP7510S2 to 1, the second VDP7510S2 to 12 (1 + 11), the third to 23 (12 + 11) and so on.
7. Cleaning and Maintenance
1. All screws should be tightened and free of corrosion.
2. The housing, visible parts, 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. Moving mechanic 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.
8. Contact your dealer for spare parts if necessary.
