Adder Technology 5000 manual Multiple video head connections

Multiple video head connections

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 on 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 or 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, see Appendix 8.

		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.
