RS485 to Ethernet Converter, Easy-to-use, High-speed, Low-power, High-stability, Upgradable

Overview
The RS485 TO ETH module provides an easy way to communicate between RS485 and RJ45 port Ethernet, it can be configured via webpage.

Features
1. M0 series 32-bit ARM processor, fast speed, high efficiency
2. 10/100M Auto-MDI/MDIX ethernet interface, regardless of cross-over or straight-through cable
3. Configurable RS485 baudrate (600bps~230.4Kbps), supports five parity check options: None, Odd, Even, Mark, Space
4. Available working modes: TCP Server, TCP Client, UDP Server, UDP Client, HTTPD Client (supports GET and POST)
5. Configurable via webpage, AT commands, serial protocol, and network protocol, provides configuration protocol which can be integrated to your own software
6. Support customized heartbeat packets, make sure the connection is truthful, as well as for actively retrieving sensor data
7. Support customized registration packets, auto passing the registered packet as identifier after the connection is established, so that different devices can be distinguished
8. Support customized webpage, allows user to customize the module configuration page
9. Support RFC2217-like protocol, be able to communicate with devices whose serial setting (baudrate, data bit, etc.) may change
10. KeepAlive mechanism, detects broken connection, auto re-connecting
11. Support time-out reboot (no-data reboot), ensures a long-term stable connection, configurable reboot time
12. Support DNS domain name resolution, configurable DNS server
13. Support DHCP, auto-obtained IP or static IP
14. Firmware is upgradable via the network
15. Restore to factory settings via software and/or hardware
16. Comes with default MAC address, which is customizable
17. Provided software: module configuration software, TCP/UDP testing tool, VCOM virtual serial port software
18. Example code: host computer (socket ), VB, C++, Delphi, Android, iOS, etc.
