RS232 to WiFi Converter 2.4G/5.8G USR-DR162

Description

Compact industrial converter enabling bidirectional data transmission between an RS232 serial port and a WiFi network in the 2.4 GHz and 5.8 GHz bands. Supports IEEE 802.11 a/b/g/n standards, operating in AP, STA, and simultaneous AP+STA modes. With a built-in Modbus gateway, it enables Modbus RTU to Modbus TCP conversion, supporting integration with PLC and SCADA systems. Support for multiple network protocols (TCP, UDP, HTTP, MQTT, IGMP), configuration via web interface, AT commands, or mobile app ensures flexibility and ease of deployment. DIN-rail mounting, interference resistance, and a wide power and temperature range make this device suitable for industrial automation, smart transportation and warehousing.
