Abstract: PURPOSE: A method is provided to use a vessel electronic device interface designed according to the existing NMEA-0183 without change of hardware such as replacement of a device in the NMEA-2000 standard, thereby reducing replacement cost and time resulted from change of a communication standard. CONSTITUTION: A reception unit converts a message transmitting through RS-422 of the NMEA-0183 communication protocol to the USART(Universal Asynchronous Receiver/Transmitter) communication protocol. The control and conversion unit analyzes and converts the converted message through the reception unit using an 8bit CAN MPU chip, AT90CAN128-16AU and outputs a NMEA-2000 type message.
