Work Mode of Embedded Modules USR-TCP232-ED2

TCP Client Mode
Module starts connection to all set TCP Server, if connection fails, module
will try to reconnect till success if connection succeeds, Server will
transmit data with serial device.

TCP Server Mode

Module monitors the set and waits for TCP Client to connect data sent by serial
device will transmit to all successfully-linked Clients via module.

UDP Mode

Module sends data of serial device to the set network device. Module monitors port and sends the received data to serial device.

Application of IoT Modules USR-TCP232-ED2

Remotely manage multiple serial devices
Use network to extend serial communication distance
Multiple PC to remotely manage serial device

Various parameter setting method

Software Settings
Download settings software, search Ethernet Modules in the LAN through the
serial port server IP, name, MAC address, or the version number. Then
set the parameters you need, otherwise keep the default.
Web-page Settings
1.Open your browser and inter the default IP address of the Ethernet Modules.
2.Open the login page of Serial Server, Enter the user name and password (default admin).
3.After setting parameter, Click Save and Restart, then setting will take effect.
Serial AT commands Settings
User can set parameter by module itself without going through another
computer to configure. This setting method is used in the following
situation: user have to configure IP address and destination IP address
on site. AT command can meet the demand. After MCU connects serial
server module by TTL (UART), MCU can configure setting by AT command.
