KEYBOARD-VIDEO-MOUSE SWITCH AND OPERATING METHOD THEREOF

摘要

A keyboard-video-mouse (KVM) switch and an operating method thereof are disclosed. The KVM switch is coupled between at least one peripheral device and controlled computers. The method includes steps of: determining whether the hot-key mode of KVM switch is started; if yes, when KVM switch receives a first signal from a specific controlled computer of controlled computers, directly passing the first signal to a corresponding specific peripheral device of at least one peripheral device; when KVM switch receives a second signal in response from the specific peripheral device within a predetermined period of time, determining whether the second signal includes a specific data; if yes, replacing the specific data in second signal with an irrelevant data to form a third signal and transmitting the third signal to the specific controlled computer. The irrelevant data corresponds to the specific controlled computer and has no effect on the specific controlled computer.
