Introduction

USR-TCP232-T2 is a tiny size serial Ethernet module which can realize data bidirectional 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.

Features

• Support DHCP, automatically obtain an IP address and query IP address through serial setting protocol
• Support DNS function
• 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
