1.1 Introduction

CAN485 is used for data exchange between CAN-Bus field bus and RS-485 bus interface converter, and

supports Modbus RTU protocol. CAN485 interface converter integrated a RS-485 channel and a CAN-Bus channel

can be easily embedded using RS-485 interface for communication nodes, do not need to change the original

hardware architecture enables the device to obtain the CAN-Bus communication interface, to achieve between the

equipments of RS-485 and CAN-Bus network connection and data communication. RS-485 channel CAN485

devices to support a variety of baud rate, the range is 300bps~115200bps. CAN-Bus channel support CiA

recommended a variety of standard baud rate and user-defined baud rate, the range of 2.5Kbps~1Mbps. CAN485

interface converter provides three types of data conversion: transparent conversion, encryption conversion and

Modbus protocol conversion.

Its exterior design supports DIN-Rail mounting and Wall mounting, which is convenient for engineering

application. The board comes with a photoelectric isolation module, complete electrical isolation control circuit and

CAN-Bus communication circuit, so that the CAN485 converter has a strong anti-interference ability, greatly

improving the system in the harsh environment of the use of reliability.
