CANSwitch-AN2S2

High-Performance Dual-CAN to Ethernet Switch User Manual

User Manual

1. Functions

1.1 Overview

The CANSwitch-AN2S2 is a high-performance industrial-grade Ethernet and

CAN-bus data conversion device developed by Guangzhou ZLG Electronics Co., Ltd. It

integrates two CAN-bus interfaces and two Ethernet interfaces, and provides a mature

and stable TCP/IP protocol stack. It helps you easily interconnect CAN-bus network and

Ethernet network, further expanding the scope of CAN-bus network. It can also be

configured in hub mode for device cascading.

The CANSwitch-AN2S2 is an industrial-grade product and works in a temperature

range of -40

℃

to +85

℃

. It has two 10M/100M/1000M adaptive Ethernet interfaces, and

the maximum baud rate of two CAN-bus interfaces is 1 Mbps. The CANSwitch-AN2S has

two modes: in the hub mode, it can realize cascading and automatic networking without

configuration, as shown in Figure 1.1; in the converter mode, it has TCP Server, TCP

Client, UDP, and other working modes. Each CAN port supports six IP segments to set a

maximum of 200 TCP or UDP connections. By using the configuration software, you can

flexibly set configuration parameters. Figure 1.2 shows a typical application.
