U1000 CAN COMM CIRCUIT



Description



CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle multiplex communication line with



high data communication speed and excellent error detection ability. Modern vehicle is equipped with many electronic control units, and each



control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are



connected with 2 communication lines (CAN H-line, CAN L-line) allowing a high rate of information transmission with less wiring. Each control



unit transmits/receives data but selectively reads the required data only.
