DeviceNet Connectors

DeviceNet allows different connectors, which may be grouped into open and sealed
connectors. The open connectors are available with screw or with crimp connectors. The
sealed connectors are available in mini-style and micro-style sizes. See
for more details.

Termination of the DeviceNet Network

The DeviceNet network uses the Controller Area network (CAN) bus as the physical
layer. This requires that the trunk line of your DeviceNet network be terminated with a
resistor at each end. This terminates the signal lines.
The terminating resistor:
• Prevents reflection of communication signals on the network.
• Connects the two signal conductors.
• Must be sealed if the end node uses a sealed tee.
• Must be open if the end node uses an open-style tap.
When using the open-style terminating resistor, connect a 121ohms, 1/4W resistor to
CAN_H and CAN_L (between blue and white data-pair wires).
NOTE: A terminating resistor must also be used whenever a short drop
line exceeds 6m (20 ft.).
