1. Product Overview
1.1 Brief Introduction
ECAN-401 is a small intelligent protocol conversion product independently developed by Chengdu Ebyte
Electronic Technology Co., Ltd. The product uses 8V ～28V wide voltage power supply,
integrates 1 CAN-BUS interface, 1 RS485 interface, 1 RS232 interface and 1 RS422
interface, which can realize two-way conversion between CAN and RS485/RS232/RS422
different protocol data. The product supports serial AT command configuration and host
computer configuration device parameters and working modes, and supports five data
conversion modes including transparent conversion, transparent conversion with logo,
protocol conversion, Modbus RTU conversion, and user-defined (user). At the same time,
ECAN-401 intelligent protocol converter has the characteristics of small size, easy
installation, and high protection isolation design for CAN interface. It has a very high cost performance in the
development of CAN-BUS products and data analysis applications. It is an engineering application and project
debugging. And reliable assistants for product development. .
1.2 Feature

3.3.3 RS232 connection method
3.3.4 CAN connection method
The linear topology is the most commonly used in the CAN bus wiring specification. That is, the two lines of the main
trunk branch out branch lines to each node. Both ends of the backbone are equipped with suitable terminal resistors to
achieve impedance matching (usually 120 ohms within 2km).
