3.12.2 CANopen Communication
Notes for connecting the CANopen communication cable:
ƒ Use 26 or 28 AWG twisted pair shielded cables. For best results, the shield
should have aluminum foil and be covered by copper braid with a drain wire
ƒ Connect the shield to the ground of the host (PC). Usually, this connection is
soldered internally inside the connector at the PC end. You can use the drain wire to
facilitate connection.
ƒ The CANopen communication port is non-isolated.
ƒ The male RJ plug must have a shield cover.
ƒ Ensure that the shield of the cable is connected to the shield of the RJ plug.
The drain wire can be used to facilitate the connection.
ƒ For "daisy-chain" connections, connect a termination 120-ohm resistor at each of the
two ends of the network cable.
