AirMax VS® high speed signal connectors from FCI meet the dimensional and electrical requirements described in the CompactPCI® Serial (PICMG CPCI-s.0) Specification developed by the PCI Industrial Computer Manufacturers Group (PICMG). Connections between a front system or peripheral board and backplane are accomplished using right-angle headers and vertical receptacles. The interface to a rear I/O board uses right-angle receptacles and vertical headers. The open pin field design of AirMax VS® signal connectors provides flexibility to use pins for differential or single-ended signals, ground or power.

The CompactPCI® Serial Specification moves Compact PCI architecture to high-speed serial interconnects to add greater support for serial point to point fabrics like PCI Express®, SATA, Ethernet and USB in the classic CompactPCI form factor with mechanics fully compliant to IEC 1101. The specification contains definitions for both system and peripheral slots in 3U and 6U board sizes and also allows hybrid systems integrating legacy CompactPCI boards and newer CompactPCI Serial boards to simplify the migration to to serial interconnect technologies.
