### 4. Functionality

The cPCI-9112 integrates multiple data acquisition functions into a single CompactPCI module:

- Analog Input (A/D Conversion):
Converts analog signals into 12-bit digital data using a successive approximation ADC (ADS774 or equivalent). Supports both single-ended and differential configurations for flexible signal interfacing.

- Analog Output (D/A Conversion):
Two 12-bit DAC channels provide precise voltage outputs for control or waveform generation. Output ranges are software-selectable and can use internal or external reference voltages.

- Digital I/O:
16 input and 16 output TTL channels allow for control, monitoring, and interfacing with external digital devices.

- Timer/Counter:
The onboard 8254 timer provides programmable timing, event counting, and frequency generation capabilities.

- Triggering & Synchronization:
Supports software, timer, and external triggers for flexible acquisition control.

Applications:
- Industrial process monitoring and control
- Laboratory instrumentation and automation
- Data logging and signal analysis
- Energy management and environmental monitoring
- Product testing and quality assurance
- Event counting and frequency measurement
