### 4. Functionality

The PXI‑20XX/25XX 6U Option integrates the 743X digital I/O subsystem into PXI instrumentation systems. Each channel is optically isolated, providing galvanic separation between field signals and the host computer.

Operation Principle:
- Digital Inputs: Use opto‑couplers with open‑collector transistor structures. Inputs can be configured as current‑sourcing or current‑sinking depending on the external wiring (common ground or common power).
- Digital Outputs: Employ Darlington transistor arrays to sink current from external loads. Fly‑wheel diodes protect against inductive kickback when driving coils or relays.
- Interrupts: Two independent interrupt sources (INT1, INT2) can be triggered by input transitions on channels 0 and 1.
- Software Control: All I/O operations are accessible via ADLINK’s PCIS‑DASK driver library or through high‑level environments (LabVIEW, VEE, ActiveX, OPC).

Typical Applications:
- Industrial and laboratory automation
- Event and frequency counting
- Pulse generation and timing control
- Watchdog and safety interlocks
- Relay and solenoid actuation
- Data acquisition front‑end for PLC or SCADA systems

Compatibility:
- PCI and CompactPCI backplanes (32‑bit, 33 MHz)
- PXI‑2000 6U chassis integration
- Supported OS: DOS, Windows 95/98/NT/2000
- Supported APIs: C/C++, Visual Basic, Delphi, LabVIEW®, HP‑VEE™, ISaGRAF™, InTouch™, InControl™, OPC
