Serial to Ethernet USR-TCP232-T2 (E8) Introduction of Modules

Serial to Ethernet USR-TCP232-T2 Serial to Ethernet converter module can realize data bidirectional transparent transmission between serial TTL and RJ45 Port. USR-TCP232-T2 is based on Cortex-M0 core. It has characters of low power, fast speed, and high efficiency.

Features of Serial to Ethernet USR-TCP232-T2 (E8)

  • DHCP &DNS, automatically obtain an IP address and query IP address through serial setting protocol.
  • Set parameters through webpage and serial AT command.
  • Upgrade firmware via network.
  • Auto-MDI/MDIX, RJ45 port with 10/100Mbps.
  • Serial port baud rate from 600 bps to 460.8 Kbps, Check bit of None, Odd, Even, Mark and Space.
  • Work mode: TCP Server, TCP Client, UDP Client, UDP Server, HttpD Client.
  • Support virtual serial port and provide corresponding software USR-VCOM.
  • Heartbeat package mechanism to ensure connection is reliable, put an end to dead link.
  • User-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.
  • The global unique MAC address bought from IEEE, user can define MAC address.
  • Restore factory default.
  • 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
