4.2. Basic Equipment Information

The backend server can use the AT+GTBEI command to configure several overall configuration

of the equipment, including „over speed alarm‟, „report information periodically‟ and „SIM contact

menu visibility‟.

4.2.1 Over Speed Alarm

The backend server can set a speed threshold for the terminal. The terminal will report its position

and speed to the backend server when its moving speed is over this threshold. The setting of over

speed alarm is done by the AT+GTBEI command.

Please note that the terminal will check the speed every time after a successful GPS fixing.

Example:

Enable “over speed alarm”: AT+GTBEI=gt300,,,0,80,0,0,10,116.228.221.61

,7003,,,0,0001

This command will enable “over speed alarm” and the speed threshold is 80km/h.

The acknowledgement from the terminal:

+ACK:GTBEI,135790246811220,0001,20090112104725,000A,0102070202

The over speed alarm is reported from the terminal:

+RESP:GTEST,135790246811220,1,0,0,1,85.3,92,70.0,1,121.354335,31.222073,2009010100000

0,0460,0000,18d8,6141,00,11F0,0102070202

To disable over speed alarm, just set the speed threshold to “0”:

AT+GTBEI=gt300,,,0,0,0,0,10,116.228.221.61

,7003,,,0,0001
