Model
Use this option to specify the model of your GPS receiver. Supported units at this time are:
a) Generic : Support for generic NMEA GPS receivers that conform to the NMEA 0183 standard and emit the GPRMC sentence at regular, precise intervals of one or two seconds.
b) Garmin 38 : Hand held GPS receiver from Garmin Corporation.
c) Garmin II Plus : Hand held GPS receiver from Garmin Corporation with support for external antenna connection. This option includes the Garmin III Plus and the Garmin V.
d) USGlobalSat BU-353: USB GPS from USGlobalSat. USB to COM port driver (included with GPS) must be installed.
Serial Port
Use this option to specify the serial port on your PC to which the GPS receiver is connected.
Speed
Baud rate to communicate with the attached GPS.
