### 4. Functionality

The EX9132BI functions as a wireless serial bridge, converting data between Bluetooth and wired serial interfaces (RS-232, RS-422, RS-485). It allows legacy serial devices—such as PLCs, sensors, meters, and controllers—to communicate wirelessly with Bluetooth-enabled systems or PCs.

Operation Principle:
- The converter receives serial data from a connected device and transmits it over Bluetooth using the Serial Port Profile (SPP).
- Conversely, it receives Bluetooth data and outputs it through the selected serial interface.
- The device automatically detects the serial interface type and configures the communication parameters accordingly.
- Built-in isolation and surge protection ensure reliable operation in electrically noisy environments.

Use Cases:
- Industrial automation and control systems
- SCADA and remote monitoring
- Data acquisition from sensors and meters
- Wireless connection to PLCs or CNC machines
- Replacement of serial cables in existing systems
- Integration of Bluetooth-enabled HMIs or tablets with serial devices

Compatibility:
- Compatible with standard Bluetooth devices supporting SPP profile
- Works with Windows, Linux, and embedded systems supporting virtual COM ports
- Integrates with ExpertDAQETM configuration software and web-based management tools
