Shielded cable
Note:
1. It is suggested to use 120Ω terminal resistors on the master and the last slave.
2. Use two-wire shielded cables in a diameter of 20 AWG to ensure a quality communication.

Note:
1. It is recommended to use Daisy Chain for connection and be sure to use 120Ω terminal resistor in
the beginning and the end of the terminal arrangement.
2. GND is the grounding signal for CANopen network.
