WebJust checking? Request more information before you complete the purchase. WebNov 27, 2024 · Below is a sample CAN network in which nodes are connected with two wires, CAN High (CAN-H) and CAN Low (CAN-L). The CAN bus is terminated by 120 Ohm resistors. CAN bus termination at both ends of the bus is necessary to remove any electrical reflections on the bus and to guarantee the correct DC levels.
