1. Introduction
CAN (Controller Area Network) bus is a serial communication interface, which is
highly fault-tolerant even in harsh environments with noise. Therefore, there is often a
need in the industry to convert interfaces such as RS -232, RS-485, RS-422 or USB to
CAN interface for communication, so CAN converters are developed. For example,
when the original equipment with RS-232, RS-485, RS-422 or USB interface (referred to
as UART side, such as PC, I-8000, WinPAC-8000
…etc) needs to control or monitor
other new CAN interface equipment (referred to as CAN side), the electrical signal and
data can be converted through the CAN converter, the data of the UART side device
can be transferred to the CAN side device, or the data of the CAN side device can be
transferred to the UART side device.
In addition, the CAN converter supports three communication modes with normal
mode, pair connection mode and listen only mode. Among them, the pair connection
mode has a function similar to transparent transmission, which can transparently
transmit the data from one side to the other side.
The application architecture of the communication mode is shown in the below
figure. For details, please refer to Section 1.2.
