TTL Ethernet Module Introduction

USR-TCP232-S2 is a tiny size SMT serial Ethernet module which can realize data bidirectional transparent transmission between TTL and Ethernet Port. It can also be applied in RS232/ RS485 by level shift circuit.USR-TCP232-S2 is based on Cortex-M0 core. It has characters of low power, fast speed and high efficiency.

TTL Ethernet Module Feature

  • Auto-MDI/MDIX, RJ45 port with 10/100Mbps
  • Work mode: TCP Server, TCP Client, UDP Client, UDP Server, HTTPD Client
  • Serial port baud rate from 600 bps to 460.8 Kbps. Check bit of None, Odd, Even, Mark and Space
  • Self-defined heartbeat package mechanism to ensure connection is reliable, put an end to dead link
  • Self-defined registration package mechanism, check connection status and use as custom packet header
  • Under TCP Server mode, Client number ranges from 1 to 16. Default number is 4
  • User can set parameters via webpage, AT command, serial protocol and network protocol
  • Setting protocol is availiable, users can integrate it to their own software
  • The global unique MAC address bought from IEEE, user can define MAC address
  • Support virtual serial port and provide corresponding software USR-VCOM
  • Restore factory default via software and hardware
  • Across the gateway, switches, routers
  • Can work in LAN, also can work in the Internet (external network)
  • Provide PC TCP/IP socket programming example such as VB, C++, Delphi, Android and IOS
