Triple Serial TTL UART to Ethernet TCP/IP Module With New Cortex-M4 Kernel
SKU: TCP232-ED2 Category:
  • Description

    TCP232-ED2 Serial Ethernet Module is to transmit data from serial TTL UART to ethernet,which has characters of low price, high speed and high stability.

    TTL & Ethernet Bidirectional Transmission

    TCP232-ED2 is a triple serial ethernet module, which supports 3*TTL working at the same time. It adopts Cortex-M4 solution and its basic frequency is up to 120MHz. And the internal of the module integrates TCP/IP protocol stack.

    Product Features of ip module

    • New Cortex-M4 kernel, industrial working temperature range(-40~85℃), elaborate optimization TCPIP protocol stack, stable and reliable.
    • selectable UART port, Different port can be used together, work independently, distinguish the connected serial port via port number.
    • Auto-MIDX function, discretionarily connect cross-over or direct network cable, automatic switching.
    • Support TCP Server, TCP Client, UDP, UDP Server, HTTPD Client,websocket,  various of ethernet protocols.
    • Support virtual serial port, provide corresponding software.
    • Serial port highest baud rate from 600bps to 1024000bps(COM0 only max 256000bps).
    • wide voltage input, more applications.
    • Support DHCP, automatically access IP, can inquire the facility within network through the UDP broadcast protocol(using software USR-TCP232-E45 Setup).
    • Supply the protocol for VIP customers
    • Provide PC TCP/IP SOCKET programming example, VB, C++, Delphi, Android, IOS.
    • A built-in web page, also parameter setting via web, can customize web pages for users.
    • Can also set via UDP broadcast, provide the set up protocol.
    • Reload button, a key restore default Settings.
    • RJ45 status indicator light, RJ45 interface built-in isolation transformer, 2 KV isolation.
    • The global unique MAC address bought from IEEE, the user can define MAC address (please state when you make order).
    • Support upgrade firmware via network.
    • Support visit IP and domain name at the same time
    • Support up to 8 link from client when act as TCP Server, same data will be send to all client.
    • Can modify http server port from default port 80 for module built-in http server.
    • Support Keepalive, detect a dead link quickly and make sure the connection more stable.
