Multiple video head connections
Two or more ServSwitch CX units can 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 server is fitted with multiple
video cards or video cards with multiple video heads.
Whenever a ServSwitch CX channel is switched, it
sends an RS232 command out on its serial interface
(marked

Whenever a ServSwitch CX channel is switched, it
sends an RS232 command out on its serial interface
(marked
COM1/UPGRADE
on the rear panel). A ServSwitch CX will
switch 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 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 the ServSwitch CX devices from operating
correctly. For more details about the serial synchronisation cables, see

Notes
It is recommended that the
second SAM in each pair is a
USB-type and that it is plugged
to a vacant USB port on the host
server to derive its power.
Pairs of SAMs can be strapped
back-to-back with cable ties to
create a tidy installation.
