Multiple video head connections

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.
