1. Functions
1.1 Overview
CANSwitch-AF2S2 is a high-performance industrial-grade optical fiber and CAN-bus
data conversion device developed by Guangzhou ZLG Electronics Co., Ltd. It integrates
two CAN-bus interfaces and two 100M fiber interfaces, and provides sophisticated and
stable TCP/IP protocol stack and hard switch.It helps you easily interconnect CAN-bus
network and optical fiber network, and further expand the scope of CAN-bus network. It
can also be configured in hub mode for device cascading.
Compared with twisted pair and coaxial cable, the low transmission loss of optical
fiber greatly increases the transmission distance. In addition, the optical cable also has
the characteristics of not radiating energy, non-conducting, and non-inductive.Moreover,
there is no influence of crosstalk and mutual interference of optical signals in the optical
cable, it has excellent anti-EMI and EMC characteristics, and there is no safety problem
caused by inductive coupling in the cable.
CANSwitch-AF2S2 is an industrial grade product and works in the temperature range
of -40℃to +85℃. It has two optical fiber interfaces, and the highest baud rate of 2-way
CAN-bus interface communication is 1 Mbps. CANSwitch-AF2S2 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.
