Two or more AdderView CATxIP 5000 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 computer is fitted with
multiple video cards or video cards with multiple video heads.
Whenever an AdderView CATxIP 5000 channel is switched, it sends
an RS232 command out on its serial interface (marked

OPTIONS

the rear panel). An AdderView CATxIP 5000 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 AdderView CATxIP 5000 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

global

user configuration menus.

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 AdderView CATxIP 5000
devices from operating correctly. For more details about the serial synchronisation cables,

Appendix 8

Notes
It is recommended that the
second CAM 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 CAMs can be strapped
back-to-back with cable ties to
create a tidy installation.
