This paper designs a PS / 2 interface based on wireless data transmission system. Keyboard input data through the PS / 2 interface to rf launch module. In the 100 metres of rf receive send and receive data module, and displayed on the LCD screen. MAX232 again through the SCM, thus realize on serial communication with PC information exchange.
