TCP232-ED2

TCP232-ED2 is a Triple TTL UART to Ethernet Module, support Modbus TCP to Ethernet IP, 3*TTL working at the same time.

• Pin type
• 3 TTL Serial Ports Supporting Data Rates of up to 1024 Kbps
• 3 ports can work at the same time

Introduction of Modbus TCP to Ethernet IP Modules

This is a serial TTL to Ethernet module, used for data transparent transmission.  TCP232-ED2 is a triple serial ethernet module, which supports 3*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 Modbus TCP to Ethernet IP 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

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

Work Mode of Modbus TCP to Ethernet IP 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 Modbus TCP to Ethernet IP 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.
