An address based data packet network capable of high speeds (10/100/1000 Mbps) originally developed for the computer industry that is seeing adoption in the marine industry. Ethernet networks are designed as a star topology. Systems of three or more nodes require a hub, router or switch to facilitate all point to point connections. An NMEA standard for the transfer of NMEA 2000 messages using an Ethernet protocol is being developed that will be called OneNet. Raymarine’s current generation system that replaces the RJ45 connector with a water-proof vibration tolerant twist pin connector. Designed for the marine environment. The Raynet (F) to RJ45 Ethernet (M) adapter can be used to connect new a, c, e or gS series MFDs to the SR6 or 8 port Seatalk high speed network switch. When used in conjunction with a crossover coupler, this adapter can also convert the Ethernet connection on a RJ45 radar scanner cable, DSM or thermal camera for direct connection to an HS5 network switch, or MFD RayNet port.
