### 4. Functionality and Operation

Analog Input Functionality:
The board converts analog voltages to 12‑bit digital data stored in onboard memory. Sampling can be triggered by software, analog level comparison, or external TTL signals. Both single‑channel and multi‑channel scan modes are supported. Internal or external sampling clocks can be used, with programmable sampling intervals down to 10 µs per channel.

Analog Output Functionality:
One D/A channel outputs programmable voltages for control or waveform generation. Output range and polarity are jumper‑selectable; conversion speed is 6 µs max with ±½ LSB linearity.

Digital I/O:
Four TTL inputs and four TTL outputs (5 V logic) allow control and monitoring of external devices. DO3 can be configured as counter output; DI1/DI2 can serve as counter gate/clock inputs.

Counter/Timer:
Integrated i8254‑compatible 32‑bit counter supports up‑counting, frequency measurement, or event counting. Clock source selectable between internal 4 MHz or external TTL input.

Trigger and Sampling Control:
- Start Conditions: software command, analog level comparison, or external rising/falling edge.
- Stop Conditions: sample count, level comparison, external trigger, or software stop.
- Delay and Repeat: programmable pre‑trigger delay, post‑trigger sampling, and repeat cycles.
- Buffer Modes: FIFO (sequential) or ring (circular) memory operation.

Data Transfer:
Bus‑master DMA‑like transfer enables high‑speed streaming of sampled data to PC memory without CPU overhead.

Isolation and Protection:
Photo‑couplers and isolation amplifiers separate PC bus from external analog/digital circuits, preventing ground potential differences and noise coupling.

Use Cases:
- Industrial process monitoring and control
- Laboratory data acquisition and waveform analysis
- Sensor and transducer signal digitization
- Automated test systems
- Embedded measurement in OEM equipment

Compatibility:
Operates in any PC with a standard PCI expansion slot (5 V or 3.3 V signaling). Supports up to 16 boards per system for multi‑channel expansion.
