-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 frequencies, 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 speeds 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, making it suitable for smart factories, intelligent storage, medical systems, smart transportation, and industrial automation applications. Key Features: Dual Band WiFi: 2.4 GHz + 5.8 GHz DIN Rail Mounting: Easy installation Modbus Gateway: Modbus RTU to Modbus TCP conversion Rich Protocol Support: UDP, HTTP, MQTT, IGMP Easy Configuration via Smart App Serial to WiFi bidirectional data transmission Enables legacy serial devices to connect to local networks and the internet, transforming them into IoT-enabled devices for remote monitoring and control. Dual Band Performance: - 2.4 GHz: Up to 200 meters transmission range in open environments - 5.8 GHz: High-speed transmission with strong anti-interference performance, ideal for complex environments Functions as a Modbus gateway, connecting to PLCs, SCADA systems, or private servers for local or remote monitoring. Supports multi-host Modbus polling and flexible WiFi networking modes: - AP Mode: Allows network devices to connect to the -DR164 via Wi-Fi - STA Mode: -DR164 connects to an existing Wi-Fi network as a client - AP+STA Mode: Simultaneous operation in both AP and STA modes Note: Due to differences in lighting, angles, and screen displays, actual product color may vary slightly from images.
