As standard the AdderView Pro 8 DVI allows you to switch
dual monitors: one digital and one analogue. However, in cases
where two digital monitors are required, you can operate two
AdderView Pro 8 DVI units in a synchronised manner. This type of
operation is usually required where each computer is fitted with
multiple video cards or video cards with multiple video heads.
Whenever a AdderView Pro 8 DVI channel is switched, it sends
an RS232 command out on the serial interface (marked
OPTIONS
on the rear panel). An AdderView Pro 8 DVI will switch its
channel if it receives the same command on the serial interface.
Consequently, by linking the serial interfaces, a master unit may
be made to automatically switch one or more slave units as
shown in the diagram.
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 both devices from operating correctly. For more details
about the serial synchronisation cables, see
