### 4. Functionality
Operating Principle:
The PIO‑16/16T(LPCI)H interfaces digital signals between a host PC and external devices. Input channels accept TTL‑level signals (active low), while output channels provide open‑collector outputs that can drive external loads up to 30 V DC. Each input can generate interrupts, and a digital filter can be applied globally to suppress noise.
Use Cases and Applications:
- Industrial automation and process control
- Machine status monitoring and control
- Laboratory instrumentation and data acquisition
- Digital signal interfacing for embedded systems
- Test and measurement systems requiring high‑speed digital I/O
Compatibility:
- Operating Systems: Windows XP/2000/NT/Me/98 and Linux distributions (Red Hat, TurboLinux, etc.)
- Programming Languages: Visual C/C++, Visual Basic, Delphi, Builder, gcc, Kylix
- Software Platforms: National Instruments LabVIEW (via VI‑DAQ library)
Input Operation:
Each input channel detects a TTL‑level signal. Logical “0” corresponds to a high voltage (inactive), and logical “1” corresponds to a low voltage (active). Inputs are internally pulled up to +5 V through 10 kΩ resistors.
Output Operation:
Outputs are open‑collector transistors (74LS07 drivers). Each output sinks current when active (logic “1”) and is open when inactive (logic “0”). External pull‑up resistors or loads must be provided by the connected device.
Interrupt Handling:
All 16 inputs can trigger interrupts. The interrupt edge (rising or falling) is programmable. Interrupt mask bits enable or disable individual channels. Interrupt status bits identify which input caused the interrupt.
Digital Filtering:
A programmable digital filter (0 – 20 steps) can be applied to all inputs. The filter time is calculated as:
Filter Time = 2ⁿ / (8 × 10⁶) seconds, where *n* = 0 – 20.
This allows filtering from 0.25 µs up to 131.072 ms.
