Overview

The WIZ750SR-485 offers industrial-grade components like an ESD and surge protection IC, power indicator, communication interface, Ethernet connector, RS-485 connector, UART connector, and four LEDs: power, link, RX, and TX. On the software end, the WIZ750SR-485 includes a variety of pre-built communication protocols, such as Modbus/TCP, Modbus/RTU, Serial to Ethernet, and more.

The WIZ750SR-485 also provides a wide range of interchangeable power and communication modules, which can be easily changed depending on your specific needs. The module can be used in both 3.3V and 5V systems.

Application Fields

The WIZ750SR-485 module is designed for applications that need to connect to and communicate with various external devices. This can include industrial monitoring and control systems, automation systems, medical instruments, home automation systems, and more.

One of the major benefits of the WIZ750SR-485 is its scalability. It can be used with a wide range of external hardware devices, and easily expanded with additional modules when needed. This increases the potential communication interface options, enabling seamless integration into even complex systems.

Working Principle

The WIZ750SR-485 is based on an ARM Cortex-M3 processor, which is responsible for the communication protocol-specific tasks. The module also includes an ATMega256A microcontroller that handles the data transmission and configuration operations. The two controllers are linked together via a serial peripheral interface.

The module is based on the basic connection and communication between various physical and communication layers, such as the Application Layer, Presentation Layer, Session Layer, Transport Layer, Network Layer, Data Link Layer, and Physical Layer. The Communication Module utilizes the data frames exchanged between the physical and communication layers.

When an incoming data packet reaches the physical layer of the communication interface, the module detects the data type, then parses the protocol header, followed by parsing the protocol data. It then checks to see if the header and data frame are in-line with the current communication protocol. Once the data frame is validated, the protocol module decodes the application data and passes it to the application layer. The application module then processes the data and processes the results as needed.

In outgoing data frames, the communication module encodes the application data, then packages the data in a protocol frame, followed by sending the data frame to the physical layer. The physical layer then transfers the data to the destination device.

Conclusion

The WIZ750SR-485 is a compact and cost-effective communication interface module that offers convenient expandability. It utilizes an ARM Cortex-M3 processor and ATMega256A microcontroller to provide robust performance and scalability. The module can be used in a variety of applications and can easily be expanded with additional modules for added versatility.
