e. Stand-Alone Mode
In stand-alone mode, your VDP250SC8M2 can be used without controller. The scanner is equipped with
a built-in microphone which allows a sound-controlled operation. Select the “Master mode” to use this
function.
f. Master/Slave Mode
This operation mode allows all slave devices to operate synchronously with the master device. Connect
the DMX out of one device to the DMX in of the next using a cable with XLR jacks. Set the master device
to “No DMX sound” or “No DMX auto”. Set the address of all slave devices to 1.
g. DMX Mode
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 VDP250SC8M2.
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 VDP250SC8M2s 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 8-channel VDP250SC8M2, you will have to set the start address of the first
VDP250SC8M2 to 1, the second VDP250SC8M2 to 9 (1 + 8), the third to 17 (9 + 8) and so on.
