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