2.5. Ignition Detection
IGN (Pin4) is used for ignition detection. It is strongly recommended to connect this pin to
ignition key “RUN” position as shown below.
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.
