Abstract:
A method of using a computer and a switching device to switch two devices connected to said switching device into different interconnected modes of operation, said method involving:a) providing software in the computer permitting interface to request different interconnected modes of operation of said two devices, b) causing a first switching signal to be generated by said software in response to a request for one particular interconnected mode of operation, c) receiving that first switching signal at said switching device and controlling two switch means in said switching device with said first switching signal to provide one of four possible interconnected modes of operation of said two devices, each of said two switch means having respective ON and OFF states, whereby providing a second switching signal will provide a second possible interconnected mode of operation, providing a third switching signal will provide a third possible interconnected mode of operation, and providing a fourth switching signal will provide a fourth possible interconnected mode of operation.
