Raymarine A70 problems
Larry,
Actually, I think exactly the opposite is true. I believe NMEA multiplexers could be made using NMEA over TCP/IP on an Ethernet backbone transparently to the end NMEA device. This technique is used commonly in existing networks today, where the TCP/IP header is used exclusively for routing purposes and at the endpoint device, the TCP/IP header is stripped and the NMEA sentence is presented to the NMEA customer bit serial transparently in the normal manner. Similar devices already exist on the market as Ethernet gateways to RS232/422 devices. Additionally, advanced QOS is available for priority routing if required, preserving the advantage of manufacturer independence and all the advantages of Ethernet. I personally believe this represents a golden opportunity. Steve "Larry" wrote in message ...

Steve Meindert, no offense, but he makes NMEA multiplexers. Ethernet would be the end of that business. -- iPhone 4 is to cellular technology what the Titanic is to cruise ships. Larry |
