To minimize the signal’s reflections from the end of the cable, a line termination shall be placed close to the 2

ends of the bus. Connect both ends of the twisted pair cable (CAN_H and CAN_L) to each LT. Use line

termination whose resistance value is 120

Ω. (Resistance Tolerance: 5% maximum, Rated Power: 1/4 W

minimum).

CANopen communication cable and other recommended items

Recommended Cable Connector: CiA-recommended CANopen (CiA DR-303-1) -compatible D-Sub 9-pin

connector (DIN41652).

CANopen Recommended Transfer Cable: CiA-recommended CANopen (CiA DR-303-1) -compatible twisted

pair cables with shield.

The cable’s resistance value should be 70m

Ω/m or less.

The above diagrams shows the case used the cable connector “XM2D-0901” by OMRON Co.
