Just like the general gateways described previously, an NMEA

2000 gateway operates on the edge of the NMEA 2000 network.

As the NMEA 2000 network has specific timing requirements in the

network management layer, it is a requirement that NMEA

gateways are provided as certified hardware devices on the bus.

This means that software running on a Personal Computer using a

standard CAN interface cannot be used directly on the bus as a

gateway, as the tight timing requirements could not be met.

No need for multiplexers as used in NMEA 0183 – the bus itself is

the multiplexer
