XVME-957 VMEbus PC/AT Expansion XYCOM

The XVME-956 PC/AT family of products is designed to provide I/O expansion for Xycom’s XVME VMEbus PC/AT products. The XVME-956 consists of two sets of carrier cards and the accompanying daughter modules with either a PC/XT or PC/AT interface. When the daughter modules are installed onto a carrier, the resulting module occupies a single double-high VMEbus card slot. The XVME-956 is designed to operate with Xycom’s VMEbus PC/AT processor modules. The XVME-956 provides the following features:
• PC/AT expansion I/O in a single VMEbus card slot
• Open architecture daughter modules available from Xycom and other vendors
• Pin and socket connector scheme (no card edge connectors)
• Convenient I/O front panel connections
The XVME-956 consists of carrier cards which drive the PC/AT signals from the host XVME PC/AT, and expansion modules which provide the various PC/AT I/O functions, such as Ethernet, Solid State Disk, Serial I/O, and SCSI. The carrier cards (XVME-956/1 and XVME-956/12) are made to be compatible with Xycom’s line of VMEbus PC/AT products. The XVME-956/12 is for use with the Xycom XVME-PC/AT modules with PC/104 Expansion sites. Both the XVME-956/1 and 956/12 provide two expansion module sites and sit adjacent to the VMEbus PC/AT. The XVME-956/3 expansion kit provides the necessary standoffs and mating connectors for single module expansion on an XVME-PC/AT with an on-board PC/104 expansion site.
Two types of expansion modules are offered. Type B modules have industry standard PC/104 mechanical dimensions of 3.550″ x 3.775″. Each Type B module requires a separate Xycom front panel kit . Type A modules are 4.010″ x 5.091″ and are functionally the same as Type B modules but have an integral front panel. Type A modules do not require a front panel kit.
