UART TTL to Ethernet - UART TO ETH  ( Waveshare 12161 )

Overview

The UART TO ETH module provides an easy way to communicate between UART and Ethernet, it can be configured via web page.

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
• Auto-reconnecting, provides a reliable TCP connection
• Supports time-out reboot (no-data reboot), configurable reboot time
• Flexible serial port data framing, allows kinds of customized packeting
• Baudrate configurable, from 600bps up to 460800bps, supports five parity check options: None, Odd, Even, Mark, Space
• Supports customized heartbeat packets, make sure the connection is truthful
• Supports customized registration packets, detect the connection status, customizable packet header, make the register packets with selected MAC address
• Supports customized web page, 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
• 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
• Available working modes: TCP Server, TCP Client, UDP Server, UDP Client, HTTPD Client
• Supported protocols: IP, TCP, UDP, ARP, ICMP, DHCP, DNS, HTTPD Client
• Configurable via web page, AT commands, serial protocol, and network protocol, provides configuration protocol which can be integrated to your own software
• 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.
