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
M0 series 32-bit ARM processor, fast speed, high efficiency
10/100M Auto-MDI/MDIX ethernet interface, regardless of cross-over or straight-through cable
Configurable RS485 baudrate (600bps~230.4Kbps), supports five parity check options: None, Odd, Even, Mark, Space
Available working modes: TCP Server, TCP Client, UDP Server, UDP Client, HTTPD Client (supports GET and POST)
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.
