Switching device and multi-computer switch

Abstract

The invention provides a switching device and a multi-computer switch. The switching device is used for connecting a host computer with a computer peripheral device and comprises a PS / 2 connecting port and a controller, wherein the PS / 2 connecting port is used for coupling the computer peripheral device; the computer peripheral device is provided with a PS / 2 interface; the controller is used for electrically connecting the computer peripheral device through the PS / 2 connecting port and comprises an identification unit; the identification unit is used for receiving a peripheral control signal of the computer peripheral device and identifying the type of the computer peripheral device according to the peripheral control signal; and the controller is used for arranging a path from the signal sent by the computer peripheral device to the host computer according the type of the computer peripheral device. The switching device can be applied to the multi-computer switch, and can automatically identify the type of the peripheral device with the PS / 2 interface.

Description

technical field [0001] The invention relates to an adapter device and a multi-computer switcher, in particular to an adapter device and a multi-computer switcher capable of automatically identifying peripheral devices of a PS / 2 interface. Background technique [0002] In recent years, with the development of technology, computers or related devices, such as KVM switches, can manage and control multiple computer hosts through various peripheral devices (such as keyboards or mice). Generally, the interface used to connect the host computer and the peripheral device can be an RS232 interface or a PS / 2 interface. For a long time, the PS / 2 interface has always been one of the interface standards used to connect peripheral devices such as keyboards and mice to the host computer. [0003] Please refer to Figure 5A , which shows a schematic diagram of a peripheral device and a PS / 2 interface according to the prior art. However, the PS / 2 interface of a general keyboard and mouse c...

Problems solved by technology

However, at least 8 sets of lines (PKCLKIN-PMDATOUT) are required between the controller 14 and the switching control circuit 20 to respectively transmit the input and output signals of the keyboard and mouse, which obviously increases the hardware cost and wiring complexity
