Angry about NMEA 2000
Hot words about NMEA 2000 were tossed into a recent rec.boats.electronics thread:
“Oh, boy! Another proprietary, improperly documented, non-standard data protocol designed to keep the marine electronics assholes swimming in money for another decade…”
Yike! I believe that every phrase and implication — heck, every word — in that diatribe is wrong, though I do understand the frustration of hobbyists and small developers who want the same access to NMEA 2000 that they have to 0183. But 0183 can not do what needs to be done on today’s boats, at least not easily. For an example of “not easily” check out the data system on Steve Dashew’s new boat, mentioned earlier, especially the bigger version of the diagram below. I’ll be posting a lot about 2000 in future weeks as I test some interesting gear.
