### 4. Functionality

Operating Principle:
The AD12‑16(PCI) performs analog‑to‑digital conversion of voltage signals from external sensors or instruments. The onboard multiplexer selects input channels, which are amplified and digitized by a 12‑bit A/D converter. The resulting digital data is transferred to system memory via the PCI bus for processing or storage.

Use Cases and Applications:
- Industrial process monitoring and control
- Laboratory instrumentation and data logging
- Sensor signal acquisition (temperature, pressure, vibration, etc.)
- Automated test systems (ATE)
- Embedded measurement systems requiring PCI interface

Compatibility:
- Operating Systems: Windows 7/8/10/11, Windows Server 2003–2019, Linux kernel 2.6 or later
- Development Environments: Visual C++, Visual Basic, Delphi, C++ Builder, gcc (Linux), LabVIEW (VI‑DAQ)
- Driver Libraries: API‑AIO(WDM) for Windows, API‑AIO(LNX) for Linux

Sampling Modes:
- Software‑controlled: Immediate sampling upon command.
- Internal clock: Periodic sampling using onboard clock generator.
- External clock: Sampling synchronized to external TTL signal.

Triggering:
- Software trigger: Initiates sampling via software command.
- External trigger: Starts sampling on falling edge of external TTL signal.
- Level comparison trigger: Sampling starts/stops when input crosses a preset voltage threshold (rising/falling/both directions).

Digital I/O Operation:
- Input: Reads TTL‑level logic states (0 = Low, 1 = High).
- Output: Controls external devices by setting TTL‑level outputs.
- Bit/Byte Access: Individual bits or entire 4‑bit ports can be read/written.

Timer Function:
Programmable counter/timer generates periodic TTL pulses for synchronization or timing control. Period adjustable from 500 ns to ~1,073 s in 250 ns steps.
