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, httpsD 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
