Multiple video head connections

Two or more SmartView World 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. Such configurations are typically required in banking and engineering applications where greater video ‘real estate’ is required. Whenever the SmartView World channel is switched

it sends an RS232 command out on its serial interface (marked COM on the rear panel). The SmartView World switches 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 SmartView devices from operating correctly. For more details about the serial synchronisation cables, see Appendix 4.
