USR-TCP232-410s |Dual Ports Serial Device Server

RS485+RS232, MQTT+SSL, Modbus Gateway, Edge Computing

USR-TCP232-410s is 2 serial Port Secure Serial Device Server which can connect 1*RS232 and 1*RS485 serial devices to the TCP/IP network. It supports bi-directional communication, Modbus RTU/TCP protocol conversion, edge computing and other advanced features. This product features for its Cortex-M7 core and the main frequency is up to 400MHz, which can ensure the high processing speed and stable data transmission.



Key Features

  • Dual Serial Ports: RS485+RS232, can work simultaneously.

  • MQTT: Can connect to IoT platform with standard MQTT.

  • SSL Encryption: To ensure data communication security.

  • Edge computing: Up to 300 points, reporting data in JSON format.

  • Modbus Gateway: Modbus TCP/RTU protocol conversion.

  • Industrial Design: -40℃~+85℃, 5-36V DC power.

  • Rich Procotol: TCP/UDP/MQTT/HTTP.

  • Usr-defined Webpage: User can customize the webpage.




Serial to Ethernet,
Bidirectional Transparent Data Transmission

With serial device server, traditional serial devices can be connected to local networks and the Internet, then users can transform traditional serial device into loT device to acheive remote monitoring/controlling.




One More Thing, Modbus Gateway


Connect to PLC, SCADA system or user’s private server to achieve local or remote motoring.

  • Modbus RTU to Modbus TCP

  • Multi-Host Modbus Polling



Edge Computing,
Enabling Edge Device Connectivity In The IIOT Era


USR-TCP232-410s can collected data in Modbus RTU, Modbus TCP protocol and reporting data to IoT cloud in JSON format using MQTT or TCP/UDP/HTTP protocol. It supports up to 128 data points, and can decode and compute the collected data to reduce server’s pressure.




Custom Json

  • JSON message custom conversion

  • Supports protocol of various servers and can be used without complicated changes.



Data Dransmission Encryption

  • Supports SSL/TLS encryption in TCP client, HTTP client and MQTT operation modes.

  • Supports two-way certificates authentication.




Odering Guide

Application in Intelligent Electrical Fire Warning System

Connect fire alarm sensor to TCP232-410s via RS485/232, and TCP232-410s can send the alarm information to the remote server to remind the staff to eliminate the fire.


Smart Lighting Facilities in Factories and Mines Monitoring

The traditional lighting facilities in factories and mines are mostly controlling by people, and cannot realize linkage between manufacture and monitoring, and lead to energy wasting. USR-TCP232-410S communicates with serial lighting equipment via network, it is convenient for lighting control and can actively report the mistakes of the equipment.




Water Service System Monitoring

For now, the communication of water supply system in waterworks is still based on serial, and it is only suitable for single-machine operation and limited transmission distance, system maintenance is difficult. USR-TCP232-410s supports serial port to network, monitor the work of the equipment via TCP Server mode at any time.
