### 4. Functionality

The MCM‑204 acquires analog vibration or acoustic signals through its four simultaneous 24‑bit channels. Each channel can power IEPE sensors directly, converting raw analog signals into digital data via a high‑resolution Sigma‑Delta ADC. The onboard ARM Cortex‑A9 processor executes filtering, FFT, and user‑defined algorithms locally, transforming raw data into processed metrics such as RMS, peak, or spectral values.

Use Cases and Applications:
- Continuous vibration monitoring of rotating machinery (motors, pumps, compressors, bearings).
- Acoustic and environmental noise analysis.
- Predictive maintenance and condition‑based monitoring.
- Laboratory testing and portable DAQ applications.
- Edge data preprocessing for IoT and smart factory systems.

Compatibility and Integration:
- RESTful API for IT‑level integration (C#, Python, JavaScript).
- Streaming SDK for real‑time continuous data (C/C++).
- TCP Socket client mode for passive data transmission.
- Web Console for configuration, calibration, and mission management via browser (Chrome recommended).
- Compatible with standard IEPE accelerometers and temperature sensors.
