Don't hesitate to contact PUSR. Reliable products and services around you!
Positioned as a “trustworthy smart IIoT partner” and an industry-leading IIoT software/hardware solution provider,Jinan USR IOT Technology Limited operates in the upstream and downstream sections of the IIoT industry value chain and focuses on the R&D, production and sales of communication products in order to fulfill the mission of “connection value, and value connection”. Employing over 600 staffs, we have completed the financing of RMB 200M, and have built factories ourselves, with the capability of serving the full industry chain from chips to cloud. We devote ourselves to providing customers with communication terminals, IoT modules and cloud platform services and IoT solutions.

Dual Ports Serial Device Server
USR-TCP232-410s comes with 1*RS232 and 1*RS485 serial ports. Two ports can work at the same time. With this serial device server, traditional serial devices can be connected to the Internet/LAN network, to achieve data communication with remote SCADA system. The traditional serial devices can easily become IoT devices

Rich Product Features
? Modbus RTU/TCP protocol conversion, easy connect to SCADA system and field serial device ? Support transparent TCP/UDP/HTTP ? Heartbeat Packet: Remote server can detect abnormal disconnection from the client using this feature ? Registration Packet: The server can identify different clients by using registration packets ? Virtual-COM Software: This feature can infinitely extend the serial cable, allowing communication to no longer be limited by distance ? Support multicast, similar RFC2117 function, etc.

Jinan Factory/Suzhou Factory
PUSR IoT invested tens of millions in building two intelligent factories, which are located in Jinan and Suzhou respectively. Using advanced enterprise experience, we provide customers with stable and reliable quality and delivery through scientific and lean management. Covering the management of vendors, manufacture procedures, quality and even customers, our complete and close quality management chain assures the quality of products and services from the system perspective.
