About this item

  • Industrial RS232/RS485 to Ethernet Converter, Dual Serial Ports, which allows bi-directional transparent data transmission between RS232/RS485 and RJ45 port Ethernet, even at the same time, it can be configured via webpage.Easy-to-use, High-speed, Low-power, High-stability, Upgradable
  • M4 series 32-bit ARM processor with up to 120MHz frequency, fast speed, stable and reliable. 10/100M Auto-MDI/MDIX ethernet interface, regardless of cross-over or straight-through cable. Both RS232 and RS485 interface, allows to work independently at the same time, without interfering each other.
  • Configurable baudrate (600bps~230.4Kbps), supports five parity check options: None, Odd, Even, Mark, Space. Multi indicators, for monitoring communicating and working status. Available working modes: TCP Server, TCP Client, UDP Server, UDP Client, HTTPD Client (supports GET and POST).
  • Supports Modbus, suit for industrial application. Supports Websocket, allows bi-directional transparent data transmission with RS232/RS485 port via webpage directly. Configurable via webpage, AT commands, serial protocol, and network protocol, provides configuration protocol which can be integrated to your own software. Supports RFC2217-like protocol, be able to communicate with devices whose serial setting (baudrate, data bit, etc.) may change.
  • Supports customized heartbeat packets, make sure the connection is truthful, as well as for actively retrieving sensor data. Supports customized registration packets, auto passing the registered packet as identifier after the connection is established, so that different devices can be distinguished. Supports customized webpage, allows user to customize the module configuration page.
