2. As an automatic reporting system when a vehicle enters and leaves a defined ‘GEO’ fenced location. The
following picture shows how this works.
Up to 100 locations can be configured.
Sample setup and operation:
SMS setup
Lets say we have 3 locations where we need to know when the vehicle enters or leaves these locations. The
locations must be entered as hex code and in 'ddmm.mmmm' format.
Example: 3723.2475 hex format to send -> 2517184B or 0456.5580 hex format to send - > 04383750.
Latitude and longitude are always positive numbers.
The last entry in the table must be hex FFFFFF.
Command code sample:
05*827,38,00,414141,424242,38,01,434343,444444,38,02,454545,464646,38,03,FFFFFF,FFFFFF,0
This will setup 3 locations:
First location : latitude = 414141 (hex) and longitude =424242 (hex)
Second location : latitude = 434343 (hex) and longitude =444444 (hex)
Third location : latitude = 454545 (hex) and longitude =464646 (hex)
Then we can enable the function with command code: 05*827,37,2,0
If the vehicle enters the second location, an text message will be sent (IN
434343,444444). When the vehicle leaves the second location, another text message will be sent (OUT
434343,444444). The message sent when a vehicle leaves a location is delayed about 30-40 seconds to
make sure that the vehicle has left the location.
The GPS location table can also be updated using the ‘AVL-setup.exe’ program or the ‘server.exe’
program using GPRS.
