3.9 Synchronising LINDY CPU Switch Multiscreens for multiple
video head applications
Multiple LINDY CPU Switch Multiscreens 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 LINDY CPU Switch Multiscreen's channel is switched it sends an
RS232 command out on its serial interface. The LINDY CPU Switch Multiscreen
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.
