The receiver is compatible with SD cards of up to 32GB. The file system is FAT32.
Shortly driving the button pin (pin#25) low toggles SBF and NMEA logging on and off.
Driving the button pin low for at least 5 seconds unmounts the SD card if it was mounted,
or mounts it if it was unmounted. The SD card mount status can be checked with the
LOGLED pin (see Appendix A).
To avoid data corruption, the SD card needs to be unmounted (i.e. the LOGLED must be
off) before turning off the power supply. This can be done in two ways:
1. By entering the “ exePowerMode, StandBy ” command before turning off the
receiver.
2. By driving the button pin (pin#25) low for at least 5 seconds before turning off
the receiver.
All log files are stored in the directory /ssn/SSRC5 on the SD card.
