USR Industrial Network to RS232/485

The USR-DR134 is a compact, industrial-grade serial server device designed to enable seamless data transmission between RS485/RS232 and Ethernet ports. It supports a rich suite of protocols, including TCP, UDP, HTTP, DHCP, and DNS, along with advanced features like heartbeat and registration packets for reliable and secure connectivity. With Modbus TCP/RTU conversion and Modbus RTU to JSON, it effortlessly integrates traditional serial devices into local networks or the IoT for remote monitoring. Its ultra-small design and DIN-rail installation make it an ideal solution for space-constrained applications in industrial automation, PLCs, and SCADA systems.

USR-DR134-004

The USR-DR134 supports multi-user access, allowing multiple clients to control serial devices simultaneously in TCP server mode, while its virtual COM software extends serial communication over longer distances. With robust hardware and software watchdogs, EMC protection, and an impressive operating temperature range of -40℃ to 85℃, this device delivers stable performance in challenging environments. Equipped with a push-type connector for easy wiring and auto re-connection functionality, the USR-DR134 is designed for seamless, reliable operation in mission-critical applications.
