What is the default function of gateways/routers in a redundant NMEA 2000 network?

• A. Distribute data to multiple displays.
• B. Increase PGN encryption.
• C. Provide weather data forecasting.
• D. Manage battery charging.

Answer: (A)

Distributing data to multiple displays is what gateways/routers do by default in a redundant NMEA 2000 network. They forward PGNs between network segments so every connected device—such as displays and instruments—receives the same information. Encryption, weather forecasting, and battery charging management aren’t functions of the gateway; those tasks are outside its role. In a redundant setup, gateways also help maintain data flow by providing alternative paths, but the core purpose remains sharing data with all devices.
