3 Connecting the CAN Bus
3.1 Connection over D-Sub Connector
A High-speed CAN bus (ISO 11898-2) is connected to the 9-pin
D-Sub connector. The pin assignment for CAN corresponds to the
specification CiA® 303-1.

Low power devices (e.g. bus converters) can be supplied directly
with 5 volts over pin 1 and pin 9 of the CAN connector. Pin 1 and
pin 9 is not in use at the delivery state. For more information see
the next section 3.2.
Tip: You can connect a CAN bus with a different transmission
standard via a bus converter. PEAK-System offers different bus
converter modules (e.g. PCAN-TJA1054 for a Low-speed CAN
bus according to ISO 11898-3).
