### 4. Functionality

The EX9486C-W functions as a transparent bridge between serial devices and IP-based networks. It captures serial data from RS-232, RS-422, or RS-485 interfaces, encapsulates it into TCP/IP packets, and transmits it over Ethernet or Wi-Fi. Conversely, it receives network data and converts it back into serial format for connected devices.

Use Cases and Applications:
- Industrial automation and control systems (PLCs, sensors, meters)
- Remote monitoring and data acquisition (SCADA)
- Building management systems (BMS)
- Energy management and smart grid communication
- Legacy serial device integration into modern networks
- Wireless serial communication in manufacturing or logistics
