3.8 Synchronising AdderView DVIs for multiple video head
applications
Multiple AdderViews may be connected together so that they operate in a
synchronised manner. Synchronised operation is useful for applications that require
multiple video signals to be switched together. This type of operation is usually
required where each computer is fitted with multiple video cards or video cards with
multiple video heads. Such configurations are typically required in banking and
engineering applications where greater video 'real estate' is required. Whenever the
AdderView's channel is switched it sends an RS232 command out on its serial
interface. The AdderView switches its channel if it receives the same command on
its serial interface. Consequently, by linking the serial interfaces a master unit may
be made to automatically switch a daisy chain of slaved units as shown in the
diagram below. The slave units will require the optional power adapters because
they cannot draw their power from the video link alone.
