Power Supply Connection
PWR (pin 11)/GND (pin 6) are the power input pins. The input voltage range for this device is
from 8V to 32V. The device is designed to be installed in vehicles that operate on 12V or 24V
systems without the need for external transformers.

Ignition Detection
IGN (pin 3) is used for ignition detection. It is recommended to connect this pin to the “RUN”
position of the vehicle ignition switch as shown below.
An alternative to connect 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 transmit information to the backend server when ignition is on
and enter the power saving mode when ignition is off.
