6.1 Synchronising AdderView MATRIX MPs for multiple video head

applications

Multiple AdderView MATRIX MPs 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.
It should be noted that the synchronisation cable deliberately does not have the
transmit pin of the Slave End connector linked to the receive pin of the Master End
connector. To do so would cause the Slave unit to be able to switch the Master unit.
This would setup an endless cyclical switching sequence that would prevent the
AdderViews from operating correctly.
The AdderView MATRIX MP may be synchronised with other Adder Technology
KVM switches that support compatible synchronisation features. These include the
AdderView MATRIX and SmartView XPro products running firmware versions of
1.12 or higher.
