### 4. Functionality

Operating Principle:
Each output channel uses an opto‑coupler and transistor circuit to switch external loads such as relays, LEDs, or TTL‑level inputs. The board outputs a digital “1” to turn ON the transistor (sink current) and “0” to turn it OFF. All outputs are reset to OFF when the PC powers up.

Use Cases and Applications:
- Industrial automation and machine control
- PLC and relay control systems
- Signal output for process monitoring
- LED or indicator control
- Data acquisition and test automation
- Integration with LabVIEW or custom control software

Compatibility:
- Operating Systems: Windows (API‑DIO(WDM)/API‑DIO(98/PC)), Linux (API‑DIO(LNX))
- Programming Languages: Visual C++, Visual Basic, gcc, LabVIEW
- Hardware Interface: Standard PCI slot (32‑bit, 33 MHz)

Logic Levels:
Negative logic operation:
- Logic “0” = High level (output transistor OFF)
- Logic “1” = Low level (output transistor ON)
