USR-K7 UART Serial to Ethernet Module
The USR-K7 is a professional-grade UART to Ethernet converter that bridges legacy serial devices with modern IP networks, enabling seamless data transmission over TCP/IP protocols. Industrial automation engineers, IoT system integrators, and embedded systems developers rely on this module to retrofit older UART-based equipment into contemporary networked infrastructures without requiring hardware replacement. This module solves the critical connectivity challenge of integrating RS232/RS485 serial devices into Ethernet networks while maintaining full protocol compatibility and real-time data integrity.
Product Overview
The USR-K7 operates as a transparent serial-to-Ethernet gateway, converting UART serial data streams into Ethernet packets and vice versa using embedded TCP/IP stack technology. The module features dual serial ports supporting both RS232 and RS485 protocols, allowing simultaneous connection of multiple serial devices. Its intelligent buffering mechanism ensures zero data loss during network transmission, while the built-in Ethernet controller handles all network layer operations independently, requiring minimal host processor intervention. The device supports both server and client modes, enabling flexible network topology configurations for distributed industrial systems.
What distinguishes the USR-K7 is its robust industrial-grade design with wide operating temperature range (-40°C to +85°C), making it suitable for harsh manufacturing environments, outdoor installations, and temperature-critical applications. The module includes advanced features such as DNS client functionality, DHCP support for automatic IP configuration, and configurable serial parameters allowing baud rates from 300 to 921600 bps. Its compact form factor and low power consumption (typically under 2W) make it ideal for space-constrained installations and battery-powered remote monitoring systems.

How to Use
Begin by connecting your RS232 or RS485 serial device to the appropriate port on the USR-K7 module using standard serial cables with proper pin configuration. Connect the Ethernet port to your network switch or router using a standard CAT5e/CAT6 patch cable. Power the module using the provided adapter (typically 9-12V DC). Access the web-based configuration interface by entering the module's IP address in your browser to configure network settings, serial parameters, and protocol modes. Set the baud rate, data bits, stop bits, and parity to match your serial device specifications, then save the configuration.
For TCP server mode operation, the USR-K7 listens on a specified port for incoming Ethernet connections and forwards all received data to the serial port. For client mode, configure the destination IP address and port of your remote server. Test connectivity by transmitting data from your serial device and monitoring the Ethernet traffic using network diagnostic tools. The module's status LEDs indicate power, network link, and data transmission activity, providing immediate visual feedback for troubleshooting. For complex multi-device installations, use the module's advanced features such as serial port multiplexing and protocol bridging to optimize network bandwidth and reduce latency.
Frequently Asked Questions
Can the USR-K7 handle simultaneous RS232 and RS485 connections?
Yes, the USR-K7 features dual independent serial ports allowing simultaneous operation of one RS232 device and one RS485 device. Each port maintains separate configuration settings for baud rate, data format, and protocol mode, enabling flexible multi-device integration within a single module.
What is the maximum cable length for serial connections to the USR-K7?
RS232 connections support standard cable lengths up to 15 meters for reliable operation at typical baud rates. RS485 connections can extend up to 1200 meters depending on baud rate and cable quality, making it suitable for long-distance industrial installations. For extended distances, use shielded twisted-pair cabling and proper termination resistors.
Does the USR-K7 support DHCP automatic IP assignment?
Yes, the module includes built-in DHCP client functionality enabling automatic IP address assignment from your network DHCP server. You can also configure static IP addresses through the web interface if your network requires fixed IP addressing for critical infrastructure applications.
Is the USR-K7 suitable for outdoor and harsh industrial environments?
Absolutely. The USR-K7 is specifically designed for industrial deployment with operating temperature range of -40°C to +85°C, making it suitable for outdoor installations, manufacturing floors, and temperature-critical environments. Its rugged construction and wide voltage tolerance ensure reliable operation in harsh conditions.
What network protocols does the USR-K7 support?
The module supports TCP/IP, UDP, DHCP, and DNS protocols. It can operate in both TCP server and client modes, allowing flexible network topology configurations. The transparent data conversion ensures compatibility with most industrial protocols running over TCP/UDP transport layers.
