The NMEA 2000 transmits data through Controller Area Network (CAN bus). It simplifies the connection and shares information among different devices by using a single trunk cable. Compared with NMEA 0183 in “RS422” interface, NMEA 2000 has better transmission reliability and shares data easily in a network.
NK-80 is a gateway between NMEA 0183 electronics devices and NMEA 2000 device/network. NK-80 allows users to connect NMEA 2000 network with their existing NMEA 0183 devices.
Key Feature of NK-80:
‧Upgrade NMEA 0183 equipment to NMEA 2000
‧Conversion between NMEA 2000 and NMEA 0183
‧Full NMEA 2000 compliance
‧Full NMEA 0183 compliance
‧Compact size, easy for installation
‧Isolation between NMEA 0183 and NMEA 2000
‧Fully galvanically isolated for electrical spike protection |
