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 unauthorized 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.
