Objective of NMEA
I am an NMEA neophyte. I am trying to connect my Raymarine speedo,
depth, and wind indicator. They use SeaTalk. Apparently, SeaTalk is not NMEA language. I thought the point of NMEA was to make multiple manufactures equipment communicate, much like MIDI (musical instrument digital interface) works for electric guitars, keyboarsd, and synthesizers. I have a Garmin GPS, which does have some NMEA capabilities. I would like to connect it to my ICom VHF, for the DSC feature. I would also like to connect my sounder to the GPS to show depth on the Garmin. Is this possible? Does anyone know where to get more information about NMEA and connecting these various devices? I've already learned a bit, but have a long way to go. Also, from what I hear, the issue of "daisy chaining" is somewhat resolved by the new NMEA 2000 protocol. Easy connectors, simple wiring. Still, NMEA reminds me of DOS based computing. (it amazes me that windows has DOS underlying it!) I am sorry I bought my Ray Marine instruments that are not NMEA compatible, if that's the word. Apparently, if I get a multiplexer, I can make Sea Talk convert to NMEA. I'm sure all this junk is in it's infancy, and one day will be resolved by some very cool technology. It's already pretty cool, especially the Blue Tooth multiplexer made by a company I don't know but recommended by someone on a google group. anyone that cares to discuss this, I'm listening. thanks Luc |
