¿µ¹®³»¿ë¿ä¾à Transport of NMEA PGN Network Messages as well as other protocols over IPv6-based networks (this aligns with M2M, IoT industry trends).
With a range of 100 Megabit to 10 Gigabit transfer speeds directly to OneNet Devices, Ethernet is about 400 to 40,000 times faster than NMEA 2000.
NMEA OneNet allows larger and more complex networks to be created than can be achieved with the 252 address limitation on NMEA 2000. NMEA OneNet contains PGN Virtual Devices that communicate on the network through a single OneNet Device.
With Power over Ethernet (PoE), each Physical Device may be separately powered up to 25.5 Watts directly from the Ethernet Switch.(Refer to IEEE 802.3at)
Ethernet is used everywhere in homes, offices and industrial environments and is well understood. Many marine electronic products already implement and support Ethernet.
In the standard the requirements of service broadcasting which each application on the device should provide by using RFC 6762 mDNS and 6763 DNS-SD are presented.
