Dual TTL UART to Ethernet Module

Introduction of TTL to Ethernet Module

This is a serial TTL to Ethernet module, used for data transparent transmission. USR-TCP232-E2 is a dual serial ethernet module, which supports 2*TTL working at the same time. It is based on Cortex-M4 solution and its basic frequency is up to 120MHz. And the internal of the module integrates TCP/IP protocol stack.

Features of TTL to Ethernet Modules

• Cortex-M4 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
• Provide PC TCP/IP socket programming example such as VB,C++,Delphi,Android and IOS
• Built-in webpage;also can customize webpage for users
• 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,realize bidirectional transparent transmission bewteen webpage and serial 0
• Support Modbus RTU to Modbus TCP
• Support UDP broadcast function

Application Field of TTL to Ethernet 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

Data Submitted to Web Server Directly

Work Mode of TTL to Ethernet Modules

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 TTL to Ethernet Modules

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.
