### 4. Functionality

The AP1T2-I-1 functions as a PCI-based serial communication interface card that allows a single COM port to be shared or mirrored across two physical connectors. This design is particularly useful in industrial automation systems where a single serial data stream must be simultaneously accessed by two devices for polling and acknowledgment operations.

Operational Principle:
- The card installs into a standard PCI slot and is automatically recognized by the system BIOS.
- The PCI BIOS assigns I/O addresses, memory mapping, and IRQ resources dynamically.
- Each of the two DB9 connectors mirrors the same COM port signal, allowing dual access.
- DIP switches on the card allow users to select the communication standard (RS232, RS422, or RS485) for each connector, depending on the model variant.
- The ASIX MCS9865 controller ensures stable, high-speed serial communication with full compatibility for legacy and modern systems.

Use Cases and Applications:
- Industrial control systems requiring redundant or mirrored serial communication.
- Poll & Ack communication environments where two devices must share the same COM port.
- Data acquisition systems, PLC communication, and SCADA interfaces.
- Serial device testing and monitoring setups.
- Integration into embedded systems or industrial PCs requiring isolated serial connectivity.

Compatibility:
- Operating Systems: Windows 2000, XP, Vista, Windows 7/8, Linux, and other compatible OS.
- Hardware: Compatible with both 5V and 3.3V PCI slots, ensuring flexibility across various motherboard designs.
