This design uses a wide range of uses infrared munication technology designed a puterbased logic analyzer infrared serial port, this project was supported by SM0038 infrared receiver head, STC89C52 microcontroller, MAX232 level converter, DB9 constitute the hardware part, by the next crew procedures and upper Machine procedures constitute software. Design logic analyzer can be a variety of electrical infrared remote control signal emitted by the identification, storage and reproduction. Hardware interface can be identified by infrared infrared signal and sent to MCU processing, then use the VB development of virtualization software on a puter screen realtime display of the infrared signal waveforms collected to facilitate the designer of various modulation infrared signals visual of analysis and research. Key words： Serial Infrared munication Infrared logic analyze.
