### 4. Functionality

The ACL‑Express‑7 serves as the high‑speed physical link in ADLINK’s PCI Express‑to‑PCI extension architecture. The system operates as follows:

1. Host Interface:
A PCIe‑8560 card is installed in the host computer’s PCI Express x1 slot. This card transmits PCI Express signals through the ACL‑Express‑7 cable.

2. Cable Transmission:
The ACL‑Express‑7 cable carries high‑speed differential signals over a shielded twisted‑pair copper medium, maintaining signal integrity across distances up to 7 meters.

3. Remote Interface:
At the remote end, a PCI‑8565 card installed in the extension chassis (RK‑8005 or RK‑8014) receives the PCI Express signals and converts them into a standard PCI bus.

4. PCI Expansion:
The extension chassis provides either 4 or 13 full‑size PCI slots (depending on model), allowing multiple PCI devices to operate as if directly connected to the host system.

Use Cases and Applications:
- Industrial Automation and Control: Enables remote placement of PCI I/O cards near machinery while keeping the host PC in a safe environment.
- Electronics Manufacturing Test: Facilitates high‑density I/O setups for automated test equipment (ATE).
- Military and Aerospace: Supports ruggedized test systems requiring remote operation and EMI isolation.
- Video Capture and Processing: Allows distributed video acquisition systems with minimal latency.
- Remote Test and Measurement: Ideal for DAQ (Data Acquisition) systems where sensors and DUTs (Devices Under Test) are located away from the host PC.
- Hazardous Environments: Protects host computers from vibration, shock, or temperature extremes by isolating them from the test area.
