This paper analyzes the superiority of data acquisition equipment based on Ethernet, raises a design of data acquisition terminal on Ethernet based on network single chip processor MC9S12NE64. and demonstrates that comparing with other multiple chips＇solutions, the superiority of this scheme. The software and hardware design details are illustrated in this paper. The selection and reduction process of TCP/IP stack and the implementation of application program based on the stack are important in it. This scheme is flexible,and it is able to be implemented in some different application fields.
