CAN connection

The connection between the SMART ONE and the controlled charging stations is made via a CAN bus by
a twisted shielded pair cable. The CAN bus cable is connected onto the terminals CAN+ and CAN-. Both
CAN+ and CAN- terminals must be used if the SMART ONE is located in the middle of the CAN bus.
The maximum CAN bus line length is 200 meters.
The CAN bus must have a termination resistance of 120 ohm at each end:
