Table 22. Serial outputs
Note that it is easy to overload the serial port if there are too many events. The software
computes the number of characters that will be output each second and displays this at
the bottom of the window. A serial port data overflow warning message will appear if the
data rate is too high for the selected baud rate; to fix this it is necessary to lower the data
rate of the selected NMEA sentences or increase the baud rate.
Selecting “Allow extended length messages” enables the full GGA and RMC messages
to be output, which are longer than the NMEA specification allows. Please see the NMEA
0183 Description manual for more details. Selecting “Output approximate values before
initialisation” forces output of the raw GNSS measurements before the RT is initialised.
Currently just the position is output and this is the position of the antenna, not the inertial
measurement unit. Note that there will be a jump (from the antenna to the inertial
measurement unit) when initialisation occurs.
