Step 5: Erasing logs
CT5510’s logging system doesn’t automatically delete old log data but
always creates new logs or appends data to the previous log. While it’s often
advantageous to have several logging sessions in memory at the same time,
eventually the memory will be filled up if old log data isn’t erased.
Using NMEA protocol
The log data is deleted with the following command:
$PFST,LOGCLEAR<CR><LF>
Step 6: Disable logging
When the logging system is configured as described above, a new log
is created each time when navigation is started. To stop using the
logging capability, the logging can be disabled by setting the start mode to
zero.
Using NMEA protocol
The logging start mode is set to zero with the following command:
$PFST,LOGMODE,0<CR><LF>
Summary
This chapter describes the quick steps for using the CT5510 logging system.
1. [No action needed at first step if the default logging settings are ok.]
2. Set logging start mode to “3”,
NMEA : $PFST,LOGMODE,3<CR><LF>
3. Start navigation,
$PFST,START<CR><LF>
4. Download logged data,
NMEA : $PFST,LOGGET,1<CR><LF>
5. Erase log data,
NMEA : $PFST,LOGCLEAR<CR><LF>
6. Disable logging,
