6.1 Synchronising LINDY CPU Switch Dual MPs for multiple video 

head applications 

 

Multiple LINDY CPU Switch Dual MPs may 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. Such configurations are typically required in banking 

and engineering applications where greater video 'real estate' is required. Whenever 

the LINDY CPU Switch’s channel is switched it sends an RS232 command out on its 

serial interface. The LINDY CPU Switch switches 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 a daisy chain of slaved units as 

shown in the diagram below. 

 

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 

LINDY CPU Switches from operating correctly. 

 

The LINDY CPU Switch Dual MP may be synchronised with other LINDY KVM 

switches that support compatible synchronisation features. These include the LINDY 

CPU Switch Dual Junior and CPU Switch Dual / Quad products running firmware 

versions of 1.12 or higher.
