3.2.5 Synchronizing multiple units

ServSwitch Wizard VGA (USB) units can be connected together so that they operate in a synchronized manner. Thus, two KV3004A units can be made to switch two video heads in a similar manner to an KV3204A. Additionally, two KV3204A units could be made to resemble an KV3404A, while two KV3404A units could be combined in order to switch up to eight video heads simultaneously.

Whenever an ServSwitch Wizard VGA (USB) channel is switched, it sends an RS232 command out on its serial interface (marked OPTIONS on the rear panel). A ServSwitch Wizard VGA (USB) unit 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 Figure 3-15.

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 Wizard VGA (USB) devices from operating cor- rectly. For more details about the serial synchronization cables, see Appendix C.
