-DR164 Serial to Dual Band WiFi Converter -DR164 is an ultra-small dual band WiFi serial server device with one serial port. It enables transparent transmission between RS485 and WiFi devices. Supports 2.4 GHz and 5.8 GHz WiFi, compatible with IEEE 802.11 a/b/g standards. The 2.4 GHz band provides extended signal range, while the 5.8 GHz band delivers faster data rates and improved resistance to interference. Designed for wide operating temperature ranges, DIN-Rail mounting, and supports multiple protocols including MQTT, UDP, HTTP, and IGMP. Features Modbus RTU conversion and is ideal for applications in smart factories, intelligent storage, medical systems, smart transportation, and industrial automation. Key Features: Dual Band WiFi: 2.4 GHz + 5.8 GHz DIN Rail Mounting: Easy installation Modbus Gateway: Converts Modbus RTU Rich Protocol Support: UDP, HTTP, MQTT, IGMP Easy Configuration via Smart APP Serial to WiFi with Bidirectional Data Transmission Enables legacy serial devices to connect to local networks and the internet, transforming them into IoT devices for remote monitoring and control. Dual Band Performance: - 2.4 GHz: Up to 200 meters transmission range in open areas - 5.8 GHz: High-speed transmission with strong anti-interference performance, suitable for complex environments Functions as a Modbus gateway, connecting to PLCs, SCADA systems, or private servers for local or remote monitoring. Supports Modbus RTU to Modbus TCP conversion and multi-host Modbus polling.
