4. Functionality

The cPCIS‑2551/AC serves as a self‑contained CompactPCI subsystem chassis. It houses a 3U CompactPCI backplane (cBP‑3206) that interconnects CPU and peripheral modules via a 32‑bit PCI bus. The integrated AC power supply (cPWR‑1500A) delivers regulated DC outputs to the backplane through a PICMG 2.11‑compliant 47‑pin connector. Cooling fans draw air from the bottom and exhaust it through the rear, maintaining optimal thermal conditions for high‑density boards.

The 6.3‑inch TFT LCD provides local display capability for system status, diagnostics, or operator interface. It can be driven by an optional CompactPCI LCD controller card (e.g., cPCI‑8215 or cPCI‑8217) via standard digital RGB interface.

Typical Applications:
- Industrial automation controllers
- Data acquisition and measurement systems
- Embedded computing platforms
- Communication and network control nodes
- Portable or wall‑mounted instrumentation

Compatibility:
Fully compatible with ADLINK CompactPCI CPU boards, I/O modules, and power backplanes. Supports standard CompactPCI signaling and mechanical interfaces per PICMG 2.0 R2.1.
