USR-DR301 is a tiny size RS232 to Ethernet converter, which can realize the bidirectional transparent transmission between RS232 and Ethernet.

USR-DR302 is a tiny size RS485 to Ethernet converter, which can realize the bidirectional transparent transmission between RS485 and Ethernet.

USR-DR404 is a Din-rail Wi-Fi serial device server which can realize bidirectional transparent transmission between RS485 and WiFi / Ethernet.

USR-DR504 is an Industrial cellular RS485 4G LTE Modem with European band with RS485 port, it can realize the data transmission between RS485 and 4G Network.

USR-G786 is an industrial 2G/3G/4G LTE Modem with high stability and anti-interference. It can realize the data transparent transmission between serial port RS232/RS485 and wireless network. The two-way data transmission from serial port to network server can be easily realized by setting simple AT commands.

USR-K5 is used for data transmission between TCP/UDP packets and the UART interface. USR-K5 is integrated with TCP/IP protocol stack, users can use it easily to complete the networking function of embedded devices, save manpower, material resources, and development cycle in the development process so that the product can be put into the market faster, enhance competitiveness. The width of Embedded Ethernet module USR-K5 is the same as the ordinary RJ45, USR-K5 has been rigorously tested and has been successfully applied in banks, highways, large corporate networks, and complex network environments such as fiber-to-Ethernet.

USR-MB706 is a RS232/RS485 to GSM 4G LTE with GPS/Glonass/Galileo/Beidou support. Used for transparent data transmission.
