    The high speed RS-422 serial communication interface board is designed by using the universal asynchronous serial communication contrler. The embedded PC is used as control center. The dual-port RAM is used as data buffer and its control program is explicated in detail. The high communicate speed, strong data storage ability and simple access are proved by application.
