CAN Communication (on the COMM.2 Ports)
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 male RJ plug must have a shield cover.
Ensure that the shield of the cable is connected to the shield of the RJ plug. The drain wire can
be used to facilitate the connection.
Connect a termination 120-Ω resistor at each of the two ends of the network cable.
