The power supply should come from batteries or direct current.
1. When in a vehicle, power supply can come from the vehicle batteries through the fuse box.
2. When using a battery or DC power supply, the output voltage range should be within 9-36V.
3. ACC should connect to vehicle ignition controller.
Speed signal and Serial ports
The vehicle speed can be read from an CAN port or GPS.

Important hint:
1. Before connecting the ACC cable to the ignition wire of the vehicle, make sure that the
vehicle is turned off.

still 9-36V after the ACC is turned off.
