【Abstract】 In this paper the DF1 protocol of A-B company is applied to the design of remote Ethernet communication system, and the communication among the devices of the A-B company is carried out by means of Ethernet modem. In the system the AT instruction is adopted for configuring the modem,which reduces the rate of error codes in channels and enhances the stability of the communication. The results indicate that this system is of a high value for application.更多还原
