CAN controller | It controls CAN communication signal transmission and reception, error detection, etc.
Transceiver IC | It converts digital signal into CAN communication signal, and CAN communication signal into digital signal.
Noise filter | It eliminates noise of CAN communication signal.
Termination circuit* (Resistance of approx. 120 Ω) | It produces potential difference.
*: These are the only control units wired with both ends of CAN communication system.
