Multiple video head connections

Two or more MC5 units can be connected together	REMOTEREMOTE
so that they operate in a synchronised manner.	USER	USER
Synchronised operation is useful for applications	U S	U S
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 MC5 channel is switched, it sends an
RS232 command out on its serial interface (marked

COM1/UPGRADE on the rear panel). An MC5 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 MC5 devices from operating correctly. For

computer to derive its power.

Pairs of CAMs can be strapped back-to-back with cable ties to create a tidy installation.
