3.8 Synchronising CPU Switch Smart DVIs for multiple video head
applications
Multiple CPU Switch Smarts 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
CPU Switch Smart's channel is switched it sends an RS232 command out on its
serial interface. The CPU Switch Smart 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.
