<State>: The current motion state of the device.
16 (Tow): The device attached vehicle is ignition off and it is towed.
1A (Fake Tow): The device attached vehicle is ignition off and it might be towed.
11 (Ignition Off Rest): The device attached vehicle is ignition off and it is motionless.
12 (Ignition Off Motion): The device attached vehicle is ignition off and it is moving
before it is treated as being towed.
21 (Ignition On Rest): The device attached vehicle is ignition on and it is motion less
22 (Ignition On Motion): The device attached vehicle is ignition on and it is moving
41 (Sensor Rest): The device attached vehicle is motionless without ignition signal
detected
42 (Sensor Motion): The device attached vehicle is moving without ignition signal
detected
<ICCID>: The ICCID of the SIM card.
<CSQ RSSI>: The signal strength level.
<CSQ BER>: The quality of the GSM signal. The range is 0-7, 99 for unknown.
<External Power Supply>: Whether the external power supply is connected.
0: Not connected
1: Connected
<External Power Supply VCC>: The voltage of the external power supply.
<Backup Battery VCC>: The voltage of the backup battery. The value of this field is only
valid when the external power is not connected.
<Charging>: Whether the backup battery is charging when the main power supply is
connected.
0: Not charging
1: Charging
<Last Fix UTC Time>: The UTC time of the latest successful GPS fixing.
<Analog Input VCC>: The voltage of the analog input.
<Digital Input>: A bitwise hex integer to represents the logical status of the digital input.
From the lowest bit to the highest bit, each bit represents ignition detection and the digital
input 1 respectively. For each bit, 0 means disable status, 1 means enable status.
<Digital Output>: A bitwise hex integer to represents the logical status of the digital output.
