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

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.

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.
