Input 1 or Input 2 or Input 3
Lock Switch
When the lock is opened, there will be negative triggering to Input 1 or Input 2 or Input 3, then 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)
0x0267=>615(decimal)=>(615*6)/1024=3.603515625V(voltage)
