Let's get rid of NMEA
Bill,
The problem is across the entire marine spectrum, not just pleasure craft. There are thousands of commercial vessels that not only bus the nav gear through NMEA and other IMO approved interfaces,but now also host Ethernet networks as well. The IMO is a very conservative and at times very backward organization. I do not agree with Meindert, but he does raise very valid points. NMEA 2k is better than 0183, but it doesn't hold a candle in transport capability or flexibility in comparison to Ethernet. It is no longer necessary nor desirable to host stove pipe transports for different purposes. The world has changed. I am an electronic engineer that has been involved with both IT and aircraft instrumentation for 40 years. the world has changed, we need to keep up. Ethernet and TCP/IP is used by billions world wide. Implementing this technology allows this "very small" market place you speak about enjoy the cost advantage of a technology used by the world. Steve "Bill Kearney" wrote in message t... "Steve Lusardi" wrote in message ... Meindert, Very nice to hear from you again. You have been away quite some time. I can't believe I am hearing this from you. You are the perfect person for this thread. I think you need to think a bit outside of the box. As you know, each NMEA manufacturer today is addressing the inadequacies of NMEA with their own propriety solutions and selling them as the next best thing in boat electronics, like SeaTalk WERE reinventing, past tense. NMEA2000 is the solution for it, and it works QUITE well. Yet we have a huge, inexpensive commercial infrastructure all around TCP/IP and yet the marine industry is trying to reinvent the wheel. You should revel in this foolishness and consider this as a golden opportunity to develop a transport network like the CAN bus SAE J1939 standard, but using TCP/IP as the flexible transport medium. Which screams of how little you understand about instrumentation networks. I think the market is huge. There are a lot of floating customers out their just waiting for this. I call bull****. List actual numbers, not pie-in-the sky hopes. Please also keep in mind that this same transport can also move all data types including other, unrelated traffic like audio, video and other computer related data streams. Which, again, screams of how little grasp you have of how instrumentation networks function. |
