Overview

The RS232/485 TO ETH is an industrial RS232/RS485 to Ethernet converter, 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.

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.
