    Not sure if I understand the question, NMEA is a GPS output format that contains all the data. When a GPS is used with RaceChrono, the GPS receiver sends the NMEA over to RaceChrono which parses it to an internal format. Normal GPS (like the XT) sends atleast $GPGGA, $GPRMC, $GPGSA and $GPGSV sentences. RaceChrono can handle a few other sentences too.
  • what i whant to know which are the perfect NMEA settings for better Racechrono result?
    thats why i was asking you the meaning and funcionality of each NMEA.
  • Default settings are the best. RaceChrono will change them anyways :)
