\"NMEA<\/figure>\n

Navigointielektroniikassa tulee usein vastaan kaksi termi\u00e4: NMEA 0183<\/strong> ja NMEA 2000<\/strong>. Molemmat ovat vene-elektroniikan tiedonsiirtoprotokollia, mutta eroavat toisistaan merkitt\u00e4v\u00e4sti.<\/p>\n

Technical Foundation<\/h2>\n

NMEA 0183<\/strong> on kehitetty 1980-luvulla, perustuu RS-422-sarjaporttiin. Tiedonsiirto on yksisuuntaista \u2013 yksi laite ”puhuu”, muut ”kuuntelevat”. Tiedonsiirtonopeus on 4 800 bps.<\/p>\n

NMEA 2000<\/strong> perustuu CAN-v\u00e4yl\u00e4\u00e4n, tiedonsiirtonopeus 250 000 bps. Verkkomuotoinen rakenne: kaikki laitteet liittyv\u00e4t samaan runkokaapeliin T-liittimien kautta. K\u00e4ytt\u00e4\u00e4 vakioituja Micro-C-liittimi\u00e4.<\/p>\n

Compatibility and Usability<\/h2>\n
    \n
  • NMEA 0183<\/strong> \u2013 yksinkertainen, mutta tukee vain yht\u00e4 ”puhujaa” kerrallaan<\/li>\n
  • NMEA 2000<\/strong> \u2013 useat laitteet voivat l\u00e4hett\u00e4\u00e4 ja vastaanottaa samanaikaisesti<\/li>\n<\/ul>\n

    Applications<\/h2>\n
      \n
    • NMEA 0183<\/strong>: Vanhemmat laitteet, AIS, GPS tai kaikuluotain yksisuuntaisesti plotterille<\/li>\n
    • NMEA 2000<\/strong>: Nykyiset verkot. \u00c4lykk\u00e4\u00e4t anturit, moottorit, polttoaine, autopilotti \u2013 samassa verkossa<\/li>\n<\/ul>\n

      Installation and Expandability<\/h2>\n
        \n
      • NMEA 0183<\/strong> \u2013 kaapelointi monimutkaistuu nopeasti lis\u00e4laitteita lis\u00e4tt\u00e4ess\u00e4<\/li>\n
      • NMEA 2000<\/strong> \u2013 ”plug and play”: laitteet liitet\u00e4\u00e4n T-haaroilla runkokaapeliin<\/li>\n<\/ul>\n

        Summary<\/h2>\n

        Valitse NMEA 0183<\/strong>, jos k\u00e4yt\u00f6ss\u00e4si on vanhempi j\u00e4rjestelm\u00e4 tai budjetti on rajallinen.<\/p>\n

        Valitse NMEA 2000<\/strong>, jos rakennat uutta j\u00e4rjestelm\u00e4\u00e4 tai haluat modernin, helposti laajennettavan verkon.<\/p>\n

        NMEA 2000's flexibility, speed, and easy expandability make it the clear winner in new boat installations.<\/p>","protected":false},"excerpt":{"rendered":"
