The use of the multi-serial/Ethernet conversion gateway simplifies the networked control and distributed management of information for serial devices. So the design of a new type of gateway for data converting from serial ports to Ethernet based on embedded system is highlighted in this paper. The design is based on ARM7 (LPC2138) processor and serial ports to Ethernet data conversion gateway that will convert the serial data of various components to Ethernet data. The communication between the serial devices and monitor computer is simplified with the Ethernet protocol. Data transmission from number of serial devices used in industrial applications can be effectively achieved. The use of such system will improve the CPU efficiency of the system to ensure real-time data processing.
