3.1.2 Field bus connectors
If you are using a not galvanic isolated CAN interface, field bus ground (CAN
GND) and USB ground (GND) have the same potential.
Using a CAN interface with galvanic isolation, these grounds are separated.
Please be care, that in this case the grounds of the field busses (CAN1 / CAN
2 / LIN) have no galvanic isolation among each other.
For best noise immunity, the shields of the CAN cables must directly connect-
ed to ground.
Pinning of the single row female headers for field bus connections are listed
below (see also Figure 3-1).
