3.12.2. CAN Communication
Notes for connecting the CAN 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 Ω resistor termination at each of the two ends of the network
cable.
The Whistle and Tweeter's CAN ports are non-isolated.
