For the foreseeable future, every new GPS sensor and VHF radio will include at least one NMEA 0183 output port. Understanding how to configure and wire it ensures your electronics will never be "dead in the water." When buying a new device, always check the technical specifications for "NMEA 0183 Output Sentences." A cheap GPS may only output GGA and RMC, but a sailing instrument may output MWV, MTW, and VHW. Ensure your Talker speaks the sentence your Listener needs to hear. nmea 0183 output

But what exactly is "NMEA 0183 output," and how do you use it effectively? NMEA 0183 is an electrical and data protocol standard defined by the National Marine Electronics Association (NMEA). Unlike a home computer network, it is a point-to-point (often called "one talker, multiple listeners") serial bus. $GPGGA,123519,4807
