Which description best matches the Gateway's function?

• A. It provides navigation charts on board.
• B. It acts as a power supply for the backbone.
• C. It imports data from NMEA 0183 onto the NMEA 2000 network.
• D. It repeats heartbeat messages to all devices

Answer: (C)

Gateways bridge two NMEA standards by translating data between them. They take information from NMEA 0183 devices (like legacy GPS, wind, or depth instruments) and convert it into NMEA 2000 messages so that everything on the NMEA 2000 backbone can use that data. That translation is why importing data from NMEA 0183 onto the NMEA 2000 network is the best description of a gateway’s function. It isn’t about providing navigation charts, powering the backbone, or simply repeating heartbeat messages, which are roles for other devices or parts of the system.
