- Signals marked with 1 correspond to the CiA assignment (CAN in automation).
Both signals CAN_L and CAN_L1 and/or CAN_H and CAN_H1 are linked internally and used to loop
the CAN bus through.
Assigning CAN_EN_in to the supply potential (= +Vin) enables the terminal to be switched on.
The signals '-Vin' and 'CAN_GND' are directly linked with both connectors, therefore it is crucial to
avoid differences in potential between the pins of these two connectors.
