Typical Ignition Detection
IGN (Pin3) is used for ignition detection. It is strongly recommended to connect this pin to
ignition key “RUN” position as shown. If you do not connect the ignition detection, not all
functions of the device will be available.
An alternative to connecting to the ignition switch is to find a non permanent power source
that is only available when the vehicle is running. For example the power source for the
FM radio.
IGN signal can be configured to start transmitting information to backend server when
ignition is on; and enter power saving mode when ignition is off.
