USR-W610 Serial to Wi-Fi Converter RS232/RS485 Ethernet 2.4GHz

The USR-W610 Serial to Wi-Fi Converter is a high-performance industrial communication device designed to enable seamless wireless data transmission between RS232/RS485 serial devices, Ethernet networks, and Wi-Fi systems. Built on a reliable Qualcomm-based platform, it provides stable and secure connectivity for industrial IoT, automation, and remote monitoring applications.

Supporting both RS232 and RS485 serial interfaces, the USR-W610 allows legacy and modern serial devices-such as PLCs, sensors, meters, and controllers-to connect directly to 2.4GHz Wi-Fi networks (802.11 b/g/n). This enables real-time data communication without the need for complex cabling infrastructure.

The device also features a 10/100 Mbps Ethernet port (WAN/LAN), allowing flexible deployment as a wired or wireless gateway. With support for TCP, UDP, HTTP(S), MQTT, WebSocket, and Modbus TCP Modbus RTU conversion, it ensures compatibility with a wide range of industrial communication protocols and cloud platforms.

Multiple operating modes-including Station, Access Point (AP), and AP + Station hybrid mode-provide versatile networking options. The converter also supports transparent data transmission and AT command configuration, making integration and setup straightforward.

Designed for harsh industrial environments, the USR-W610 operates within a wide temperature range of -40 C to +85 C and features 2kV electromagnetic isolation on the Ethernet port, ensuring stable operation in electrically noisy conditions.

Security is a key focus, with support for WEP, WPA-PSK, and WPA2-PSK encryption, ensuring safe wireless communication. The device can handle up to 24 simultaneous TCP client connections, making it suitable for scalable IoT deployments.
