Description

Details

This product is subject to IC short supply, higher cost, and longer lead time, please consider the 2-CH UART TO ETH for new design.
UART TTL to Ethernet Converter, Easy-to-use, High-speed, Low-power, High-stability, Upgradable

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.
