SMT Serial Ethernet Module ■ ■ ■ USR-TCP232-S2 Serial Ethernet data transmission USR-TCP232-S2 is a tiny SMT serial TTL UART to 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. ■ ■ ■ TTL to Ethernet ■ Support DNS function and custom setting of DNS server ■ Support DHCP, automatically obtain an IP address ■ Support customization Specifications System Information Processor Serial Port Number Interface Standard None, Even, Odd, Space, Mark Baud Rate ■ Serial port baud rate from 600 bps to 460.8 Kbps, Check RS485 Pull-up and Pull-Down Resistor bit of None, Odd, Even, Mark and Space ■ Upgrade firmware via network Null, reserved 485 send-receive control pin ■ Work mode: TCP Server, TCP Client, UDP Client, UDP Rate Server, HTTPD Client 10/100 Mbps, MDI/MDIX, auto switch between cross and direct connection ■ Auto-MDI/MDIX, RJ45 port with 10/100Mbps ■ Restore factory default via software and hardware Interface Standard Port Number ■ Self-defined heartbeat package mechanism to ensure connection is reliable, put an end to dead link Network Protocol IP, TCP, UDP, DHCP, DNS, HTTP, ARP, ICMP ■ Self-defined registration package mechanism, check connection status and use as custom packet header ■ The global unique MAC address bought from IEEE, user Buffer can define MAC address Send: 6K bytes Receive: 4K bytes ■ Across the gateway, switches, routers Basic Parameter ■ Support virtual serial port and provide corresponding software USR-VCOM ■ Under TCP Server mode, Client number ranges from 1 to 16; default number is 4 Operating Temp. ■ Can work in LAN, also can work in the Internet Storage Temp. ■ Provide PC TCP/IP socket programming example such as VB, C++, Delphi, Android and IOS Input Voltage ■ User can set parameters via webpage, AT command, serial protocol and network protocol; and setting protocol is Working Current provided, users can integrate it to their own software Software Virtual Serial (USR-VCOM) Configuration Windows 2000 or higher (32 bit/64 bit) Computer set-up software Serial command Built-in webpage AT command Jinan USR IOT Technology Limited Tel: 86-531-88826739 Email: sales@usriot.
