9.2 Detecting Lock Status of Car’s Door or Trunk (Car Boot).

When the lock is opened, there will be a negative trigger to Input 1 or Input 2 or Input 3. After this, an SMS alarm will be sent to

the authorized phone number, or a GPRS alarm will be sent to the server (please refer to the GPRS Command 0x9999 in GPRS

Communication Protocol).

9.3 Connecting with Switch Sensors

The SMS alarm will be sent to the authorized phone number.

9.4 Ignition Detection

Input 4 or Input 5 (positive triggering) can be used for ignition detection. The detection alarm will be sent to the server via GPRS.

Please refer to <GPRS Communication Protocol> Alarm Command 0x9999 for more information.

9.5 Analog Input (AD1 and AD2)

Input voltage should be 0~6V. Please refer to GPRS Communication Protocol for more information for AD1 and AD2 data.

For example:

094506.000,A,2232.5412,N,11404.6919,E,0.00,,290709,,*12|1.7|110|0000|00AA,0267

AD1 is 0x00AA and AD2 is 0x0267.

Voltage Formula: Input Voltage=(AD*6)/1024

0x00AA=>170(decimal)=>(170*6)/1024=0.99609375V(voltage)
