### 2. Key Features

- 48-Channel Bi-Directional Digital I/O:
Provides 48 unisolated TTL-level I/O channels, configurable as input or output in 8-bit units (4-bit units for certain ports).
Compatible with the functional equivalent of Intel i8255 Mode 0 operation.

- High-Speed Response:
Achieves a response time of 200 nanoseconds, enabling fast digital signal processing suitable for real-time control systems.

- Interrupt Functionality:
All 48 input channels can be used as interrupt inputs. Interrupts can be enabled or disabled per bit, and the triggering edge (rising or falling) can be selected individually.

- Digital Noise Filter:
Integrated digital filter function prevents false signal recognition caused by noise or contact chattering. Filter parameters are software-configurable.

- Driver and Software Support:
Bundled with API-PAC(W32) driver library supporting both Windows and Linux environments.
Includes API-DIO(WDM) and API-DIO(98/PC) for Windows, and API-DIO(LNX) for Linux.
Compatible with LabVIEW via the VI-DAQ library for seamless integration with National Instruments environments.

- Connector Compatibility:
Uses a 68-pin 0.8mm pitch female connector (HDRA-F68LFDT+ by Honda Tsushin Kogyo or equivalent).
Connector and pin assignments are compatible with CONTEC’s CardBus model PIO-48D(CB)H and PCI model PIO-48D(PCI), simplifying system migration.

- Dual Bracket Support:
Supplied with interchangeable brackets for both Low Profile and Standard PCI slots.

- RoHS, CE, and VCCI Certified:
Complies with major environmental and electromagnetic compatibility standards.
