USR-TCP232-T2 is Serial UART to/over Ethernet/LAN Module for bidirectional
data transparent transmission between UART and RJ45 Port. It is based on ARM processor and internally integrated Cortex-M0 core. User can configure parameter by web server or software to realize remote data acquisition, remote control and management.
Built in Web Server/Webpage for configuration.
User can modify the webpage.
HTTP Client: send data as HTTP format automatically. Serial data submitted to server by HTTP (GET/POST).
DHCP: automatically obtain an IP address and query IP address.
DNS address and MAC address can be modified.
Synchronous and adaptive serial port baud rate.
Registration packet: identified header can be added to packets to check
Heartbeat packet: can be sent to serial or network periodic. To ensure connection is reliable, put an end to dead link. ????
Support router/bridge mode networking.
Can work in LAN, also can work in the Internet (external network)
Protocol: IP, TCP, UDP, DHCP, DNS, ARP, ICMP, HTTP Client.
1) Parameter configuration software.
2) Virtual serial port software(VCOM), Windows 2000 or higher (32 bit/64 bit)
Configuration method: (Manual P43)

TCP/UDP Transparent Transmission Mode
Serial Ethernet Module TCP232-T2 can work as TCP Client, TCP Server, UDP Client,
UDP Server Mode.
1)In TCP Client Mode: Client connects Server automatically. The IP and COM number of Client should be same as Server.
2)In TCP Server Mode: The Max Client number can be modified from 1 to 16. By default, Client number is 4.
3)In UDP Client Mode: UDP broadcast function, send and receive data from all IP in the network.
4)In UDP Server Mode: send data from serial port to Target IP.
