4.22 S6 - CAN0 Interface
The CAN0 interface is equipped with a CAN transceiver module and is not isolated. A 120-Ohm
terminating resistor (R22) is provided between the CANLOW and CANHIGH signal (DSUB 9 female).
Additionally it is possible to connect the power supply to pin 9 of the DSUB connector S6 by placing a
0 Ohm resistor at R10. #
