The Design of Asynchronous Serial Interface Detection Apparatus

This paper introduces a design of the asynchronous serial interface detection apparatus. The device communicates with the host computer via the serial interface. Firstly, the PC control produces a particular signal source and provides the source data to the asynchronous serial communication module. Meanwhile the PC uses the device to generate fetch clock to bring back PCM stream data and send back to the host computer to carry on the analysis. At last it detects the communication process in order to detain some outcomes.
