Step 3: Start navigation
When the logging settings have been configured as described in the previous
sections, logging starts automatically as navigation is started.
Navigation is started by:
!
Giving the NMEA command $PFST,START<CR><LF>
!
Resetting the CT5510 module (assuming that the auto-start after power-up
is enabled [on by default]).
Step 4: Downloading logged data
After the CT5510 has been navigating and logged, the logged data can be
downloaded to PC in the following ways:
Using NMEA protocol
1. Stop navigation to finish the logging session.
2. Read the number of logs that are in CT5510’s memory, as new logs
are created each time when logging is started with the given settings. The
number of logs can be displayed with the
$PFST,LOGNUM command, e.g.
$PFST,LOGNUM<CR><LF>
The system responds with a message containing the number of logs,
e.g.
$PFST,LOGNUM,1*32
This shows that there is one log currently in the memory.
3. The logged data can be outputted using
the command “
$PFST,LOGGET,<N> ”, where <N> is the log number of
interest. This command outputs the logged data in standard NMEA format.
For example, the following command will display all data in log 1:
$PFST,LOGGET,1<CR><LF>
NOTE: If there are plenty of data in the log, it may take some time to output
all the data as NMEA messages. To speed-up the operation, it is advised to
increase the NMEA port speed or disable some of the NMEA messages.
