Triple Serial TTL UART to Ethernet TCP/IP Module With New Cortex-M7 Kernel
This is a serial TTL to Ethernet module, used for data transparent transmission. USR-TCP232-ED2 is a triple serial ethernet module, which supports 3*TTL working at the same time. It is based on Cortex-M7 solution and its basic frequency is up to 120MHz. And the internal of the module integrates TCP/IP protocol stack.
Features of Modbus TCP to Ethernet IP Modules
- Cortex-M7 kernel, industrial working temperature range and TCPIP protocol stack.
- Auto-MDI/MDIX, RJ45 port with 10/100Mbps
- TCP Server, TCP Client, UDP Client, UDP Server and HTTPD Client work mode
- Multi-ports can work independently at the same time
- Can distinguish which serial port connects to the device via port number
- Support virtual serial port and provide corresponding software USR-VCOM
- Serial baud rate from 600bps to 1024K bps; Check bit of None, Odd, Even, Mark and Space
- DNS and DHCP supported

- Reload button, one key to restore default settings
- RJ45 with Link/Data indicator light, built-in isolation transformer and 2 KV electromagnetic isolation
- The global unique MAC address bought from IEEE (begin with D8-B0-4C); user can define MAC address
- Support upgrade firmware via network
- Support keepalive, rapidly detect dead links
- Support account and password can be used to page login and network settings
- Support one channel Websocket, realise bidirectional transparent transmission between web page and serial 0
- Support Modbus RTU to Modbus TCP
- Support UDP broadcast function
Application Field of Modbus TCP to Ethernet IP Modules
- Industrial data transmission, industrial automation
- security and protection monitoring, public security
- Smart home, power control, environmental monitoring, intelligent agriculture
- Door check on work attendance system, POS system, rice selling system
- Building automation system, power monitoring, self-service banking system, telecom machine room monitoring
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
- Open your browser and enter the default IP address of the Ethernet Modules.
- Open the login page of Serial Server, Enter the username and password (default admin).
- After setting parameter, Click Save and Restart, then setting will take effect.
Serial AT commands Settings
The user can set parameter by the module itself without going through another computer to configure. This setting method is used in the following situation: user has to configure IP address and destination IP address on the site. AT command can meet the demand. After MCU connects serial server module by TTL (UART), MCU can configure setting by AT command.
