Q

The NMEA 2000 backbone operating speed is:

🔍 Key Concepts

• NMEA 2000 is based on a specific CAN-bus data rate • Backbone speed is measured in bits per second (bps), not bytes • Compare these speeds with typical Controller Area Network (CAN) standard bit rates

💭 Think About

• Which of these values matches a common CAN-bus standard speed used in automotive and marine networks? • Are these speeds unusually slow or fast for a modern digital backbone that carries multiple instrument data streams? • Think about whether NMEA 2000 needs low, medium, or high bandwidth to support data from many sensors and displays.

✅ Before You Answer

• Confirm the standard NMEA 2000 physical layer specification (it’s tied directly to a specific CAN standard rate). • Eliminate any speeds that would be impractically slow for multiple instruments on one backbone. • Eliminate any answers that sound like they might be confusing bits per second with another unit (e.g., bytes per second).
