The CAN communication line is a twisted pair wire consisting of

strands of CAN-H (1) and CAN-L (2) and has noise immunity.

NOTE:

The CAN communication system has the characteristics of noise-resistant because this system produces dig-

ital signals by using the potential difference between the CAN-H line and the CAN-L line and has the twisted

pair wire structure.

Since the CAN-H line and the CAN-L line are always adjacent to

each other, the same degree of noise occurs, respectively, when a

noise (1) occurs. Although the noise changes the voltage, the poten-

tial difference (2) between the CAN-H line and the CAN-L line is

insensitive to noise. Therefore, noise-resistant signals can be

obtained.

CAN Signal Communications

Each control unit of the CAN communication system transmits signals through the CAN communication con-

trol circuit included in the control unit and receives only necessary signals from each control unit to perform

various kinds of control.
