2-CH UART To Ethernet Converter is a module that allows communication between TTL UART and RJ45 Ethernet. It allows bidirectional, transparent data transmission. The module is equipped with the CH9121 chip and features high-speed data transmission, low power consumption and high stability of operation. The module allows for remote management of several client devices with multiple serial ports - all through a single web server.

Main features:
  • Built-in Ethernet MAC and PHY layers
  • Bidirectional transparent data transfer between UART and Ethernet
  • Auto-MDI/MDIX, auto detection and switching
  • KeepAlive, software update over network
  • Automatic IP address and DNS domain access via DHCP
  • Configuration of network parameters such as chip mode, port, IP, via host software or UART command
  • Four modes of operation: TCP CLIENT, TCP SERVER, UDP CLIENT, UDP SERVER
  • UART communication in full-duplex or half-duplex mode supports automatic RS485 RX/TX switch
