### 4. Functionality

The PCI‑9222 integrates multiple data acquisition and control functions on a single PCI card:

- Analog Input (AI):
Converts analog signals to 16‑bit digital data using an AD7685 ADC. Supports single‑ended or differential configurations with programmable gain and range. Data acquisition can be triggered by software or external signals and transferred via DMA for high‑speed continuous sampling.

- Analog Output (AO):
Generates precise analog voltages using a DAC8812 DAC. Supports waveform generation, static output, and hardware‑timed updates. Ideal for signal simulation, control loops, and test stimulus generation.

- Digital I/O:
Provides 16 inputs and 16 outputs for TTL‑level control and monitoring. Supports static I/O, high‑speed waveform generation/acquisition, and synchronization with analog operations.

- Timer/Counter & PWM:
Four 32‑bit timers/counters support event counting, frequency measurement, pulse generation, and PWM output. PWM channels can generate modulation frequencies from 0.005 Hz to 20 MHz with 1–99 % duty cycle.

- Encoder Inputs:
Two isolated encoder channels support CW/CCW and AB‑phase modes for position feedback in motion control applications.

- Triggering & Synchronization:
Supports software and external digital triggers for AI, AO, and DIO. Multiple cards can be synchronized via the SSI bus for multi‑channel systems.

Typical Applications:
- Automotive and aerospace testing
