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 a AdderView CATx channel is switched, it sends an RS232 command out on its serial interface (marked COM1/UPGRADE on the rear panel). An AdderView CATx 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. 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 CATx devices from operating correctly. For more details about the serial synchronisation cables, see Appendix 7. The local user ports can also be used to view multiple video head installations. 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.
