3.5.10.2. CAN Communication
Notes for connecting the CAN communication cable:
• Use 26 or 28 AWG twisted pair shielded cables. For best results, the shield should have
aluminum foil and covered by copper braid with a drain wire
• 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.
• The D-sub socket must have a shield cover.
• Ensure that the shield of the cable is connected to the shield of the D-sub socket. The drain
wire can be used to facilitate the connection.
• Connect a termination 120-ohm resistor at each of the two ends of the network cable.
