To switch between the two PCs, there is a toggle button on the switchbox. One of the main problems with having the button on the switch box itself is accessibility. But, of course, with the box off the desktop, the toggle switch will not be easily accessible. Linksys has solved this problem by allowing you to control the switch by using the keyboard. Hitting CTRL twice switches control from one PC to another, which is extremely convenient.
Control remains on the machine that was active first even when the other system is switched on.
Now, if you thought ahead a bit, you might have spotted a potential problem that would occur during the boot process. The second PC would not detect a mouse or keyboard, stopping the boot process. Fortunately, Linksys made sure this wouldn t be an issue. When the signals are directed to and from one PC to the switch, the ports on the KVM switch that connect to the other PC emulate a standard idle keyboard and mouse so that the second system will detect that input devices are present and boot correctly. If the left, then right shift buttons are pressed consecutively, the KWM switch will toggle between the two systems in 3 second intervals automatically.
