Below is a description of each format:GARMIN - the proprietary format used to exchange waypoint, track,and map data with a PC.GARMIN DGPS - Allows DGPS input using a GARMIN beaconreceiver and a standard RTCM SC-104 format and DGPS tuning.NMEA - supports the input and output of standard NMEA 0183version 2.3 data.Text Out - allows simple ASCII text output of location and velocityinformation, without any input capabilities.RTCM In - allows DGPS input using a standard RTCM SC-104 formatwithout any output capabilities.RTCM In/NMEA Out - allows DGPS input using a standard RTCMSC-104 format and supports the output of standard NMEA 0183 ver-sion 2.3 data.RTCM In/Text Out - allows DGPS input using a standard RTCMSC-104 format and simple ASCII text output of location and velocityinformation.Modem - allows connection for data transmission using a PC.
