Max time interval = 65535*10 seconds
GPRS Report Times
= 0, report without limit.
= [1,65535], set report times, T1 will stop reporting when reaching the
times.
IP & Port
Input server’s IP address and port number.
Secondary IP and Port
(Backup Server)
Input backup server’s IP address and port number to avoid data losing
when main server is down. The backup server will receive data automatically.
APN
APN user name
APN password
APN, APN username, APN password: max 32 bytes.
If no username and password required, leave them blank.

7.1.4 Output (PIN10/PIN11/PIN12)
7.1.5 Analog Input (PIN8/PIN9)
7.1.5.1 Analog Input Application 1–Detect External Power Voltage Input range：0-6V
Voltage Caculating Formula: input voltage=(AD*3.3*2)/4096
0x0C9B=>3227(Decimal)=>(3227*3.3*2)/4096=5.1997V( Voltage)
0x0D9D=>3845(Decimal)=>(3845*3.3*2)/4096=5.6154V( Voltage)
7.1.5.2 Analog Input Application 2 –Fuel Detection (percentage of fuel)
Note:
Fuel level sensors supplied by our company are resistance-type sensors with output resistance: 0-200Ω (ohm).
For the circuit shown on above figure, if VCC is 12V, R should be 200Ω (ohm) and if VCC is 24V then R should be
600Ω (ohm) to make the input range to AD1 or AD2 is 0-6V.
