1. Functions
1.1 Overview
The CANET-8E-U is a high-performance industrial-grade Ethernet CAN-bus data
conversion device developed by Guangzhou ZLG Electronics Co., Ltd. It integrates eight
CAN-bus interfaces, one Ethernet interface and TCP/IP protocol stack, which allows you
to easily interconnect CAN-bus network and Ethernet, and further expand the scope of
CAN-bus network.
The CANET-8E-U is an industrial grade product and works in the temperature range
of -40°C to +85°C . It has 100M/1000M adaptive Ethernet interface. The highest baud rate
of CAN port communication is 1 Mbps. It has various working modes such as TCP Server,
TCP Client, and UDP. Each CAN port supports multiple TCP or UDP connections. You can
flexibly set configuration parameters by using the configuration software. The following
figure shows a typical application.

100M/1000M self-applicable Ethernet interface, 2 kV electromagnetic isolation;
Eight CAN ports, 2.5 kVDC withstand voltage isolation;
CAN port baud rate 5k-1,000kbps can be set arbitrarily;
Embedded hardware watchdog timer;
Power supply voltage range 9-48 V DC;
Operating temperature: -40°C to +85°C;
Humidity: 5%-95% RH, no condensation;
Rugged metal housing, SECC metal (1.1 mm);
Designed specifically for industrial environments.
1.2.2 Perfect Functions
Static or dynamic IP acquisition;
Heartbeat and timeout disconnection;
The working port is fixed, and the destination IP address and port can be set;
After the network is disconnected, the connection resources are automatically
restored, and the TCP connection is established reliably;
Manage one CAN port while satisfying six groups of users;
In UDP mode, each CAN port supports six groups of target IP segments. Multiple
users can manage a CAN device at the same time;
Supported protocols include ETHERNET, ARP, IP, ICMP, UDP, DHCP, DNS, and
TCP;
Compatible with SOCKET working methods (TCP Server, TCP Client, UDP). The
writing of the host computer communication software follows the standard
SOCKET rules;
Two-way transparent transmission of CAN data and Ethernet data (For the
format, see Appendix 8.1);
Flexible CAN port data framing settings meet various subcontracting needs;
Each CAN port can be configured into different working modes, which can be
flexibly used in various fields;
Each CAN port opens a diagnostic port, and the host computer can obtain the
error status of the corresponding CAN port by connecting this port;
The operating parameters can be configured using the Windows configuration
software;
Provide Windows platform configuration software function library for free,
including easy-to-use API function library, which helps users write their own
configuration software;
Support local system firmware upgrade.
