IGN (Pin3)is used for ignition detection. It is strongly recommended to connect this pin to ignition
key “RUN” position as shown up.
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.
There are three general purpose digital inputs on GV300. They are all negative trigger.
