Abaco Systems / SBS 212-2 cPCI to PCI Backplane Controller Card (cPCI Card Only)

The Abaco Systems SBS 212-2 is a CompactPCI (cPCI) backplane controller card that enables 32-bit PCI connectivity within cPCI environments. This card bridges PCI host systems to cPCI backplanes, requiring a companion SBS 210-2 or 210-2A PCI host card for complete interoperability. The 212-2 operates as the cPCI interface component within a dual-card PCI-to-cPCI architecture, supporting memory-mapped I/O and Direct Memory Access (DMA) communication pathways.

Technical Specifications

• 32-bit PCI bus connectivity


• DMA sustained transfer rate: 45 MBytes/sec (Controller Mode)


• Conforms to PCI Local Bus Specification 2.0 (host card)


• Meets PICMG 2.0 specifications for cPCI (PCI 2.0 compliance)


• Adheres to IEEE 1101.1 mechanical standards for CompactPCI form factors

Key Features

• Supports both Programmed I/O (PIO) and DMA transfer modes


• Memory-mapped random access transfers between local and remote buses


• Compatible with any standard cPCI backplane and cPCI enclosure


• RoHS-compliant versions available


• Loadable device drivers and example programs included


• Cross-platform software support: Windows NT, Solaris, IRIX

Integration Requirements The 212-2 functions as part of a two-card controller set. Operation requires pairing with an SBS 210-2 or 210-2A PCI host card, compatible with any non-ATX PCI backplane. The 210-2A variant is designated for remote power-up configurations and rackmount enclosures. All SBS 32-bit PCI 20x-2 series host cards are supported. Complete system documentation, including manuals and datasheets, is available through manufacturer channels.
