Two or more ServSwitch CX Uno IP 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 an ServSwitch CX
Uno IP channel is switched, it sends an RS232 command out on its
serial interface (marked OPTIONS on the rear panel). An ServSwitch
CX Uno IP 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.
Note: You must ensure that all ServSwitch CX Uno IP units have their Options serial ports
set to ‘Sync Units’ and that their baud rates are identical. These settings can be made
either via the local or global user configuration menus.
It should be noted that the synchronization 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 IP devices
from operating correctly. For more details about the serial synchronization cables, see
Appendix 7.
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.
