Advanced Operation; Working With Nmea Navigation - Interphase PC/180 Operation Manual

5 Advanced Operation

This chapter describes several features of the PC/180
software which provide data handling and trou-
bleshooting for the more advanced operator.
Working with NMEA
Navigation
PC/180 reads standard NMEA 0183 navigation
strings from a serial port, extracts the latitude and
longitude and displays this information in the tool-
bar. PC/180 accepts GGA, GLL, RMB and RMC
strings. To activate this feature, select NMEA 0183
Setup... from the File menu, click in the check box
labeled Enable NMEA 0183 Input and select the se-
rial port to which navigation input is connected.
When NMEA 0183 input is enabled, PC/180 will
look for data coming from the serial port. If the
NMEA strings are successfully parsed, PC/180 will
display the most recent latitude and longitude in the
navigation box on the toolbar. If PC/180 does not
find data or is unable to parse the data coming from
the serial port, a series of dashes will be displayed in
the navigation box. A blank navigation box indicates
that NMEA 0183 input is disabled.
