Multiple video head connections
Two or more ServSwitch CX Uno units can be
connected together so that they operate in a
synchronized manner. Synchronized 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. Whenever a ServSwitch
CX Uno channel is switched, it sends an RS232
command out on the serial interface (marked
OPTIONS
on the
rear panel). An ServSwitch CX Uno 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 the ServSwitch CX Uno devices from operating
correctly. For more details about the serial synchronization cables, see
Appendix 2

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
computer to derive its power.
Pairs of SAMs can be strapped
back-to-back with cable ties to
create a tidy installation.
