memory. When the memory gets full, the newest record will be overwritten on top of the oldest (FIFO - First
In, First Out). In that case, only the newest information is stored.
Note:
1. X=0, to turn off this function. X=[1, 65535] to set interval in the unit of SECOND.
2. The logged message is in GPRMC format and includes:
Date and time
Longitude
Latitude
Speed
Direction
3. All data, stored within the memory, may be exported to the PC using the USB connector. For this matter
the “GPSLog” program has to be used (please refer to < GPSLog User Guide> and <GPRS Communication
Protocol> for more information).
4. The device has 4MB internal memory space for storing the track log and is able to store up to 180,000
records within the memory.
Example:
W000000,031,60
The tracker will store GPS data every 60 seconds.
13.2 Auto Log when no GPRS
When there is no GPRS connection, the tracker can store all GPS information triggered by preset tracking
interval, alarms, request, or button activation and send this information (FIFO - First In, First Out) to server
by GPRS or preauthorized mobile phone by SMS when GPRS connection recovers.
The interval memory can store up to 1500 SMS and 4600 GPRS message.
