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

5 Advanced Operation

This chapter describes several features of the PC/
View software which provide data handling and trou-
bleshooting for the more advanced operator.
Working with NMEA
Navigation
PC/View reads standard NMEA 0183 navigation
strings from a serial port, extracts the latitude and
longitude and displays this information in the tool-
bar. PC/View 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/View will
look for data coming from the serial port. If the
NMEA strings are successfully parsed, PC/View will
display the most recent latitude and longitude in the
navigation box on the toolbar. If PC/View 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.
