-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 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: Supports Modbus RTU to Modbus TCP conversion Rich Protocol Support: UDP, HTTP, MQTT, IGMP Easy Configuration: Compatible with smart app setup Serial to WiFi: Enables bidirectional data transmission Connects legacy serial devices to local networks and the internet, enabling remote monitoring and control capabilities. 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 Integration Capabilities: Connects to PLCs, SCADA systems, or private servers for local or remote monitoring Supports Multi-Host Modbus Polling Multiple WiFi Network Modes: AP Mode: Allows network devices to connect to the -DR164 via Wi-Fi STA Mode: The -DR164 connects to an existing Wi-Fi network as a client AP+STA Mode: Operates in both AP and STA modes simultaneously Design and Build: Color: As shown Material: Plastic Mounting: DIN Rail Package Contents: 1 x Converter 1 x Antenna Note: Other items not included Note: Actual product color may vary slightly due to lighting and display differences.
