Notes
CANopen recommends that all nine wires on the connector be routed to support future
network enhancements. The signals listed above are the minimum required for the
ACR90x0.
CAN_H and CAN_L should be a twisted-cable pair with a third wire run as a common ground
between nodes. If all network nodes implement isolation, CAN_GND is optional.
Connection is recommended if the network contains non-isolated nodes.
Use shielded cabling to improve network noise immunity. See Appendix on page

.
The conductor shield of the cable may be routed to pin 5, CAN_SHLD, which is terminated
with 1M
Ω
resistor to protective earth. If required, make a low ohmic connection of the
shield to the protective earth through the metal D-sub back shell.
