    Serial Ethernet Module Introduction

    USR-TCP232-T2 is a tiny size serial Ethernet module which can realize data bi-directional transparent transmission between TTL and RJ45 Port. It can also be applied in RS232/ RS485 by level shift circuit.USR-TCP232-T2 is based on Cortex-M0 core. It has characters of low power, fast speed and high efficiency.

    Serial Ethernet Module Feature

    • Set parameters through webpage, software and serial AT command
    • 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 on the Internet (external network)
    • Provide PC TCP/IP socket programming example such as VB, C++, Delphi, Android and IOS
