3.12.2 CANopen Communication
Notes for connecting the CANopen communication cable:
 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.
 Ensure that the shield of the cable is connected to the shield of the connector used for
communications. The drain wire can be used to facilitate the connection.
 Make sure to have a 120 Ohm resistor termination at each of the two ends of the
network cable.
 The Whistle and Tweeter's CAN ports are non-isolated.
