Data Submitted to Web Server Directly
Work Mode of UART over Ethernet Modules USR-TCP232-E2
TCP Client Mode
The module starts a connection to all set TCP Server, if the connection fails, the module will try to reconnect till success if connection succeeds, Server will transmit data with a serial device.
TCP Server Mode
The 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.
The module sends data of serial device to the set network device. Module monitors port and sends the received data to serial device.
Application of TTL to Ethernet Modules USR-TCP232-E2
Remotely manage multiple serial devices
Use network to extend serial communication distance
Multiple PC to remotely manage serial device
Various parameter setting method
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.
Open your browser and inter the default IP address of the Ethernet Modules.
Open the login page of Serial Server, Enter the user name and password (default admin).
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.
