Data communication apparatus for communicating data of vehicle monitoring and/or controlling system, has first controller area network (CAN) transceiver that converts differential electric signal into mass-related electrical signal

摘要

The apparatus has a first serial data port (14) for transmission of single-ended electrical signals to and from a first data terminal (10), and a second serial data port (20) for transmission of single-ended electrical signals to and from a second data terminal (12). A first CAN transceiver (34) connected to first serial data port, is arranged to convert differential electric signal into mass-related electrical signal. A second CAN transceiver (40) connected to second serial data port, is arranged to convert mass-related electrical signal into differential electric signal. An independent claim is included for method of communicating data between first data terminal and second data terminal of vehicle monitoring and/or controlling system.
