24 QUADRAVISTA 2 INSTALLATION AND OPERATIONS MANUAL
DCP Control
This mode allows direct control of a single
QuadraVista 2 by means of a control device, e.g. a
computer.
The control device can query and change the mode
of QuadraVista 2.
QuadraVista 2 responds to each DCP message sent by
the control device with a DCP reply. This reply includes
the values of all settings queried or set by means of the
last message. If the message sent by the control unit
contains errors, the QuadraVista 2 will reply by sending
an error message.
Example of DCP control
A QuadraVista 2 is controlled via DCP-XML by a computer connected by serial cable.
DCP Synchronize
Use this mode to keep several QuadraVista 2 devices in the same
mode.
Every change in settings initiated in the first QuadraVista 2 by
Hotkeys,
Hotmouse,
Front panel buttons, or
a controlling device
synchronizes the modes of all connected devices via DCP messages.
Special serial Y cables are used for this purpose
NOTE: Each time you restart QuadraVista 2 set to synchronize, it will send all its settings to the next connected
device. This process also takes place after activating synchronize in the OSD menu.
When starting a chain of devices, always start by first switching on the device at the end of the chain. When the
device has completed its startup phase and sent its DCP messages, switch on the next device in the chain.
Finally, switch on the first device in the chain, which synchronizes the settings of all other devices in the chain with its
own settings as it starts up.
