U1000 CAN COMM CIRCUIT
U1000 CAN COMM CIRCUIT
Description
INFOID:0000000000965461
• CAN communication is a multiplex communication system. This enables it to transmit and receive many
communication signals at high speed by connecting control units with two communication lines (CAN-H and
CAN-L).
• Control units on the CAN network transmit signals with CAN communication control circuit in the control unit
and receive only necessary signals from other control units for various controls.
• CAN communication lines adopt twisted-pair line style (two lines twisted) for noise immunity.
