What is the data rate of the NMEA 2000 backbone?

Explanation:
The backbone data rate is 250 kilobits per second. NMEA 2000 is built on CAN bus at 250 kbps, a speed chosen to balance reliable multi-drop communication across marine wiring with manageable cabling and device compatibility. The lower 125 kbps option would bottleneck throughput, while higher speeds like 500 kbps or 1 Mbps aren’t specified for the NMEA 2000 backbone due to the stricter cabling and timing requirements they would impose.
