Waveshare Industrial RS232RS485 to Ethernet Converter, US Plug Industrial RS232RS485 to Ethernet Converter, Dual Serial Ports, Easy-to-use, High-speed, Low-power, High-stability, Upgradable Overview The RS232485 TO ETH is an industrial RS232RS485 to Ethernet converter, which allows bi-directional transparent data transmission between RS232RS485 and RJ45 port Ethernet, even at the same time, it can be configured via webpage. Features 1. M4 series 32-bit ARM processor with up to 120MHz frequency, fast speed, stable and reliable 2. 10100M Auto-MDIMDIX ethernet interface, regardless of cross-over or straight-through cable 3. Both RS232 and RS485 interface, allows to work independently at the same time, without interfering each other 4. Configurable baudrate (600bps~230.4Kbps), supports five parity check options: None, Odd, Even, Mark, Space 5. Multi indicators, for monitoring communicating and working status 6. Available working modes: TCP Server, TCP Client, UDP Server, UDP Client, HTTPD Client (supports GET and POST) 7. Support Modbus, suit for industrial application 8. Support Websocket, allows bi-directional transparent data transmission with RS232RS485 port via webpage directly 9. Configurable via webpage, AT commands, serial protocol, and network protocol, provides configuration protocol which can be integrated to your own software 10. Support customized heartbeat packets, make sure the connection is truthful, as well as for actively retrieving sensor data 11. Support customized registration packets, auto passing the registered packet as identifier after the connection is established, so that different devices can be distinguished 12. Support customized webpage, allows user to customize the module configuration page 13. Support RFC2217-like protocol, be able to communicate with devices whose serial setting (baudrate, data bit, etc.) may change 14. KeepAlive mechanism, detects broken connection, auto re-connecting 15. Support time-out reboot (no-data reboot), ens
