Features

• 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 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
• Supports RFC2217-like protocol, be able to communicate with devices whose serial setting (baudrate, data bit, etc.) may change
• KeepAlive mechanism, detects broken connection, auto re-connecting
• Supports time-out reboot (no-data reboot), ensures a long-term stable connection, configurable reboot time
• Supports DNS domain name resolution, configurable DNS server
• Supports DHCP, auto-obtained IP or static IP
• Firmware is upgradable via the network
• Restore to factory settings via software and/or hardware
• Comes with default MAC address, which is customizable
• Provided software: module configuration software, TCP/UDP testing tool, VCOM virtual serial port software
• Example code: host computer (socket ), VB, C++, Delphi, Android, iOS, etc.
