7.1.3.4. How to use IGN pin (pin 3)
It is strongly recommended to connect this pin to the ignition key to support the IGN-power saving function when the
vehicle is off.
The IGN-pin has two functions:
 It wakes up the system FOX3-2G/3G/4G from the IGN-sleep mode (when sleeping),
 and can be used to monitor the vehicle ignition state, to report/store the trip START and STOP by using the
events IO.e8=redge and IO.e8=fedge respectively.
IGN-sleep mode is one of the eight supported energy-saving modes of the device operation in which all unnecessary
components are shut down. On IGN wake-up signal, the device returns to full functionality.
Note that, FOX3-2G/3G/4G devices power on automatically when external power is applied, and IGN pin provides an
additional "wake up" function for the IGN-sleep mode when it is requested.
In case of unauthorised vehicle access/start, you are automatically alarmed by SMS or TCP and the vehicle recovery
can be started by knowing its exact location. In such a case, use the IGN generated event as a condition to start the
vehicle tracking.
