4. Functionality
The AX10461 functions as an interface adapter that connects an ISA AT bus system to a PC/104 module. The ISA bus provides the traditional parallel communication backbone used in legacy industrial PCs, while the PC/104 connector allows for modular expansion using stackable embedded boards.

Operational Principle:
- The card plugs into a standard ISA slot on an industrial motherboard or backplane.
- The onboard PC/104 connector provides a direct electrical mapping of ISA signals to the PC/104 pinout.
- This enables PC/104 modules—such as CPU boards, I/O cards, or communication interfaces—to be integrated into an ISA-based system.
- The design ensures signal integrity and timing compatibility between the two bus standards.

Use Cases and Applications:
- Industrial Automation: Integration of PC/104 control modules into legacy ISA-based automation controllers.
- Embedded Systems: Expansion of embedded PCs with PC/104 I/O or communication modules.
- Data Acquisition: Connection of PC/104 DAQ modules to ISA-based data collection systems.
- System Modernization: Extending the functionality of older ISA systems by adding modern PC/104 modules.
- Testing and Development: Used in laboratories or production environments for testing PC/104 modules on ISA platforms.

Compatibility:
- Compatible with standard ISA AT bus motherboards and backplanes.
- Supports PC/104 modules conforming to the PC/104 specification (IEEE P996.1).
- Electrical and mechanical compatibility with both 8-bit and 16-bit ISA signals.
