3.4.8.2. CAN Communication
Notes for connecting the CAN communication cable:
• Use 24, 26 or 28 AWG twisted pair shielded cables (24 AWG cable is recommended). 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.
• Use only a D-Sub connector with a metal housing.
• Attach the braid shield tightly to the metal housing of the D-type connector.
• Connect a termination 120-Ω resistor at each of the two ends of the network cable.
• When assembling the Communication cable, follow the instructions in Section 3.4.3 (Feedback
Control and Communication Cable Assemblies).
