### 4. Functionality

Analog Input Operation:
The board converts analog voltages into 12‑bit digital data. Input mode (single‑ended or differential) and range are configured via jumpers and software. Sampling can be continuous or event‑driven, using internal or external clocks. Data is stored in the onboard 16 M‑sample FIFO or ring buffer, enabling high‑speed acquisition without CPU overhead.

Analog Output Operation:
One 12‑bit D/A channel outputs programmable voltages within ±10 V, ±5 V, or 0–10 V ranges. Output updates occur in 6 µs, suitable for waveform generation, control signals, or analog simulation.

Digital I/O:
Four TTL‑level inputs and four TTL‑level outputs allow control and monitoring of external devices. Digital lines can share functionality with counter control signals (gate, clock, output).

Counter Function:
An i8254‑compatible 32‑bit counter supports internal 4 MHz or external clocking. Configurable as a programmable one‑shot, rate generator, or event counter. Counter I/O is accessible via CN2.

Triggering and Synchronization:
Sampling can start or stop based on software commands, analog level thresholds, or external TTL triggers. External sampling clocks and start/stop triggers are supported through CN2.

Use Cases and Applications:
- Industrial process monitoring and control
- Laboratory data acquisition and signal analysis
- Automated test systems
- Sensor and transducer interfacing
- Real‑time waveform generation and logging

Software Compatibility:
- Windows 7/Vista/XP/Server 2003 (API‑AIO(WDM)/API‑AIO(98/PC))
- Linux (Red Hat, TurboLinux) via API‑AIO(LNX)
- MATLAB integration via ML‑DAQ library
- LabVIEW integration via VI‑DAQ library
- C‑LOGGER data logger for non‑programmatic operation
