Standard open-style screw connector:
Switching on the bus termination
The adapter module does not provide bus termination. The
DeviceNet network should be terminated at both ends of the trunk
cable with a 121 ohm, ¼ W, 1% metal film resistor. Connect the
resistor between the two signal wires (CAN_H, CAN_L) on the
DeviceNet cable, as shown in the figure below.
Further information on the DeviceNet protocol is available at
