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.

Function

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
