Wiring
CANopen requires a DB9 connector for data transmission. DB9 connector pins are
defined as follows:

Use shielded twisted pair cable to connect CAN bus, and attach a 120 Ω
termination resistor to each end of the bus to prevent signal reflection. Reliable
single-point grounding is often used for shield. Do not bind the cable together
with DC cable, high voltage cable, and so forth, so that communication signal will
not be interfered.
5.4 Serial communication connection through RS485
The CPU module provides a CN1 terminal as the RS485 port, as shown in the
following figure.
