Part Number: RS232/485 TO ETH

Comes with US plug power adapter. More options for the power plug: US, EU,or customation for you specail, TALK to us NOW!!!

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

• C4 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.
