Multiple video head connections
As standard the Wizard DVI DL allows you to switch dual monitors: one digital and one analogue. However, in cases where two digital monitors are required, you can operate two Wizard DVI DL units in a synchronized manner. 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 Wizard DVI DL channel is switched, it sends an RS232 command out on the serial interface (marked OPTIONS on the rear panel). An Wizard DVI DL will switch its channel if it receives the same command on the 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 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 both devices from operating correctly. For more details about the serial synchronization cables, see Appendix 2.
