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 above.
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 for the device to start transmitting information to backend server
when the ignition is on and enter power saving mode when the ignition is off.
