CAN COMMUNICATION SYSTEM
System Description
-
CAN communication is a multiplex communication system. This enables the system to transmit and receive large quantities of data at high speed
by connecting control units with two communication lines (CAN-H and
CAN-L).
-
Control units on the CAN network transmit signals using the CAN communication control circuit. They receive only necessary signals from other
control units to operate various functions.
-
CAN communication lines adopt twisted-pair line style (two lines twisted) for noise immunity.

Each control unit passes an electric current to the termination circuits when transmitting CAN communication signal. The termination circuits produce
an electrical potential difference between CAN-H and CAN-L. CAN communication system transmits and receives CAN communication signals by
the potential difference.
