4. Functionality

The cBP‑3206R serves as the electrical and mechanical backbone of a 3U CompactPCI system. It interconnects the system controller board (CPU) with up to five peripheral I/O boards through a 32‑bit PCI bus. The P1 connector carries the PCI signals, while the P2 connector (installed on the “R” variant) provides rear I/O routing to transition modules mounted behind the backplane.

Operation Principle:
- The system slot hosts the CompactPCI CPU board, which acts as the PCI bus master.
- Peripheral slots accommodate I/O or communication boards that interface with the CPU via the shared PCI bus.
- Rear I/O connectors (P2) allow signal routing to rear transition modules, minimizing front‑panel cabling.
- Power is supplied through ATX connectors or screw terminals, distributing regulated DC voltages to all slots.
- Control and monitoring signals (INH#, FAL#, DEG#, RST#) enable power management and fault detection.

Use Cases and Applications:
- Industrial automation controllers
- Embedded computing platforms
- Test and measurement systems
- Telecommunications and network appliances
- Military and transportation control systems
- CompactPCI development and prototyping environments

Compatibility:
- Compatible with ADLINK cPCIS‑2000 and cPCIS‑1000 chassis series.
- Supports ADLINK power supply modules (cPS‑150R, cPS‑175 series, APS‑925A).
- Integrates with ADLINK LCD kits (cPCI‑LCD) and mechanical frames (cPCI‑PSF, cPCI‑DBF).
- Fully interoperable with standard CompactPCI CPU and I/O boards conforming to PICMG 2.0 R2.1.
