Abaco Systems / Ramix PMC239/F PCI to PMC Adapter with Fan Option

The Abaco Systems / Ramix PMC239/F is a PCI-to-PMC adapter that enables integration of PMC (PCI Mezzanine Card) modules into PCI-based systems. The adapter bridges IEEE 1386-compliant PMC modules to PCI host interfaces, supporting both 32-bit and 64-bit PCI slots with flexible voltage signaling across 3.3V and 5V domains.

Technical Specifications

• PCI Interface: 32-bit and 64-bit PCI slot compatibility


• PMC Module Support: IEEE 1386 standard mezzanine cards


• Voltage Signaling: 3.3V and 5V PMC card support; 3.3V and 5V PCI slot compatibility


• Power Generation: +3.3V supply for PMC module operation


• Fan Cooling: 5V, 1W MagLev fan; user-disconnectable


• Debug Interface: 64-bit user I/O mapping to PMC P4 connector


• Form Factor: PCI edge connector, IEEE 1386 standard

Key Features

• Dual-voltage signaling eliminates compatibility barriers between 3.3V and 5V PMC cards and PCI slots


• On-board +3.3V regulation for PMC power distribution


• Integral MagLev cooling fan reduces external thermal management requirements


• Optional fan operation allows deployment in passive configurations


• Debug connector provides direct I/O access for in-system testing and signal monitoring


• Compact PCI-slot form factor preserves host bandwidth and system real estate

Typical Applications

• Laboratory development and PMC module prototyping


• Integration testing of PMC-based functionality in PCI environments


• Evaluation of third-party PMC hardware within legacy PCI systems

Compatibility & Integration The adapter accepts PMC modules with 3.3V or 5V signaling specifications and installs into corresponding PCI slots. Voltage compatibility is determined by the installed PMC card - 3.3V-only PMC cards require 3.3V-capable PCI slots, while 5V-only PMC cards require 5V-capable slots. The PMC239/F generates its own +3.3V rail, eliminating external power supply requirements for the mezzanine module.
