Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] The PS / 2 keyboard and mouse simulator of the present invention can control the simulator as long as the device can output the RS232 signal, and convert the input RS232 signal into a simulated PS / 2 signal to communicate with the computer. Such as figure 1 Shown, a kind of PS / 2 keyboard mouse emulator of the present invention is by RS232 signal input interface, PS / 2 keyboard signal simulation and processing unit, PS / 2 mouse signal simulation and processing unit, PS / 2 keyboard signal output interface and PS / 2 mouse signal output interface.

[0019] The RS232 signal input interface is connected to the PS / 2 keyboard signal simulation and processing unit, and the PS / 2 mouse signal simulation and processing unit, and the external RS232 keyboard signal and RS232 mouse signal are connected to the system through the RS232 signal input interface, that is, the P...

Abstract

The invention discloses a PS / 2 keyboard and mouse simulator, relates to the field of computers and solves the problem that a PS / 2 interface is limited in application when distance between a computer and a control console is long or operating space is limited due to the fact that PS / 2 signal transmission distance is limited. The PS / 2 keyboard mouse simulator is composed of an RS232 signal input interface, a PS / 2 keyboard signal simulating and processing unit, a PS / 2 mouse signal simulating and processing unit, a PS / 2 keyboard signal output interface and a PS / 2 mouse signal output interface. The PS / 2 keyboard and mouse simulator is easy in wiring and long in transmission distance, the computer can be ensured to still be capable of being correctly started without being connected with a real PS / 2 keyboard and a PS / 2 mouse; the RS232 signal input interface is adopted, so that the PS / 2 keyboard and mouse simulator has no mutual conflict with the keyboard and the mouse with which the computer is connected externally.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a PS / 2 keyboard and mouse simulator. Background technique [0002] The PS / 2 interface, used on many modern mice and keyboards as an interface on traditional PC-compatible computer systems, was developed by IBM and originally appeared in the IBM Technical Reference Manual. At present, although the PS / 2 interface has been gradually replaced by the USB interface, because the PS / 2 keyboard interface can support all keys at the same time without conflict, and will not fail when the computer is overclocked significantly, it is superior to the USB interface. , so in some occasions the PS / 2 interface is still reserved. However, compared with the USB interface, it does not support hot plugging, that is, it must be connected to the computer system before the computer is powered on; in addition, the PS / 2 signal transmission distance is limited, generally only 2 meters. The use of the PS...
