View : 2,408
Type : Serial to Ethernet Converter
Description :

This RS232 to Ethernet Converter supports 1 channel of RS-232/RS-422/RS-485 to 100Mbps Ethernet.


This DIN-rail RS232 to ethernet converter has an IP40 protection level and provides immediate networking capability, enabling centralized management of disparate serial devices and hosts over a network.

The product supports 1 channel of RS-232/RS-422/RS-485 to 1 channel of 100Mbps Ethernet and can be installed using a 35mm rail or wall-mounting method to accommodate different application scenarios.


This serial server supports multiple network protocols, including TCP, UDP, ARP, ICMP, HTTP, DNS, DHCP, and SNMP. It features comprehensive management functions such as access control, quick configuration, and online upgrading. Each serial port supports up to 4 TCP or UDP session connections and supports multiple operating modes, such as Modbus TCP, TCP Server, TCP Client, UDP Server, and UDP Client. The device also supports WEB management and comes with a Windows-based configuration tool that guides users through the management and configuration process step by step, enabling immediate networking of serial devices with simple settings. The user-friendly network management system interface offers simple and convenient operation, providing users with an excellent experience.


The hardware features fanless, low-power, wide-temperature, and wide-voltage design, and it has passed rigorous testing by industry standards to meet the demands of industrial environments with strict EMC requirements. This device can be widely used in various applications, including PLC control and management, building automation, healthcare automation systems, measurement instruments, and environmental power monitoring systems.


The RS232 to Ethernet Converter can be used in many embedded network control applications, such as:

– Industrial Automation Production

– Security Access Control: network access control, alarm devices, infrared detection alarms, and remote card readers

– Smart Home Devices: smart home gateways, smart sockets, and smart switches

– Network IO Controller: Industrial Remote IO Input, Remote Relay Control

– Building Automation and Energy Monitoring

– Medical Monitoring Equipment


1 Ch Serial RS485/RS232/RS422 to Ethernet (TCP/IP) Converter


This ethernet to 232 converter uses an ARM Cortex-M4 processor with a frequency of 192MHz.

supports 1 port 100 Mbps Ethernet, and the Ethernet supports 10/100base-T(X) adaptive. It supports auto-negotiation (Auto-Nego Full&half duplex) and auto-cross detection (MDI/MDIX).

provides 1 RS232/422/485 serial port, and supports 300bps-921600bps line-speed non-blocking communication. It supports automatic baud rate scan matching and customer-defined baud rate.

The serial data port complies with RS-232/RS-485/RS-485 related standards, and all three interfaces can be set to different bus modes through DIP switches.

The serial interface supports fiber interfaces, including 1310nm single-mode, 1310nm multi-mode, and 850nm multi-mode; ST/FC/SC is optional.

supports multiple operating modes, including Modbus TCP, TCP Server, TCP Client, UDP Server, and UDP Client.

Transparent conversion of Modbus-RTU to Modbus-TCP enables reading of serial device data over the network.

supports monitoring of serial port status and parameters, making communication status clear at a glance.

supports gateway and cross-router communication, virtual serial port driver access mode, and automatic reconnection of network interruptions.

supports flexible serial data framing settings to meet various user needs for packet fragmentation.

supports standard TCP/IP SOCKET application program access TCP and supports multiple connections, allowing up to 4 users to simultaneously monitor or manage serial devices.

In UDP mode, it supports communication between single or multiple devices, allowing multiple users to simultaneously monitor or manage serial devices.

supports multiple configuration methods, including Windows configuration tools, serial port configuration, and WEB configuration. It also supports SNMP network management.

supports local and remote system firmware upgrades.
