Abstract：In the design of the equipment of acceleration sensor volume calibration test，it need PC has a real-time monitoring of equipment，acquisition system instructions and distributed data to control the information. So the design based on RS?鄄485 of the DSP serial communication interface circuit achieved DSP and PC communications，and successfully applied in the equipment of acceleration sensor volume calibration test. The system has the advantages of simple hardware circuit，easily written software，better expansibility and portability，stable and reliable data communication.
