USR-DR164 Serial to Dual Band WiFi Converter USR-DR164 is an ultra-small size dual band WiFi serial server device with one serial port. It can realize transparent transmission between RS485 and WiFi device. It supports 2.4G & 5.8G WiFi, compatible with IEEE 802.11 a/b/g/n standard. With 2.4 G WiFi, it has longer range signal while with 5.8G WiFi, it has fast speed and better resistance to signal interference. Wide operating temperature, DIN-Rail mounting, rich protocol like MQTT/TCP/UDP/HTTP, Modbus TCP/RTU conversion and other features make it widely used in smart factory, intelligent storage, intelligent medical, smart transportation, industrial automation and other scenarios. Key Features: Dual Band WiFi: 2.4G + 5.8G DIN Rail mounting: Easy installation Modbus Gateway: Modbus TCP/RTU conversion Rich Protocol: TCP/UDP/HTTP/MQTT/IGMP Easy Configuration: Smart APlink APP Serial to WiFi, Bidirectional Data Transmission With serial to WiFi converter, traditional serial devices can be connected to local networks and the Internet, then users can transform traditional serial device into loT device to achieive remote monitoring/controlling. Dual Band WiFi, Anti-interference, Wide Coverage For 2.4G: The transmission distance can up to 200 meters in open environment; For 5.8G: It has anti-interface and high transmission speed, can work well in complex environment. One More Thing, Modbus Gateway Connect to PLC, SCADA system or user's private server to achieve local or remote motoring. Modbus RTU to Modbus TCP Multi-Host Modbus Polling Multi WiFi Networking Method AP Mode: Allow network devices to access USR-DR164 via Wi-Fi. STA Mode: USR-DR164 accesses to other networks via Wi-Fi as a network device AP+STA Mode: Work in AP and STA mode simultaneously Different ba
