USR-TCP232-S2 Introduction of Ethernet to UART modules

Ethernet to UART modules USR-TCP232-S2 can transmit data transparently between TCP/IP and TTL, which can be applied in RS232/ RS485 by level shift circuit. USR-TCP232-S2 is a tiny size embedded 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.

Features of Ethernet to UART Module USR-TCP232-S2

  • Auto-MDI/MDIX, RJ45 port with 10/100Mbps.
  • Work mode: TCP Server, TCP Client, UDP Client, UDP Server, https D 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; and setting protocol is provided, users can integrate it to their own software.
  • Support DHCP, automatically obtain an IP address.
  • Support DNS function and custom setting of DNS server.
  • The global unique MAC address bought from IEEE, user can define MAC address.
  • Upgrade firmware via network.
  • 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.
  • Support customization

Application Field of SMT Ethernet Modules
