General Details

Introduction of SMT Ethernet Modules

USR-TCP232-S2 are tiny size SMT Ethernet modules 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.

Feature of SMT Ethernet Modules

  • 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; 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

  • Industrial data transmission, industrial automation
  • security and protection monitoring, public security
  • Smart home, power control, environmental monitoring, intelligent agriculture
  • Door check on work attendance system, POS system, rice selling system
  • Building automation system, power monitoring, self-service banking system, telecom machine room monitoring
