Figure 7. Typical Ignition Detection
IGN (Pin6) 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.
3.6. Digital Input
There is a general purpose digital input on GV35. It is negative trigger.
