XYCOM Adapter Module XVME-976 PC Expansion Board dual-slot version

XYCOM XVME-976 PC Expansion Board dual-slot version The XVME-976 adapter module provides I/O expansion for Xycom’s XVME-654 and XVME-655 VMEbus PC/AT processor modules. Direct connection is possible with the XVME-654. Connections with the XVME655 require a transition board, such as the XVME-978/1 Ethernet card, or XVME-978/100 transition module, which plug into the XVME-655 and provide the mechanical and electrical connections for the XVME-976.

MODULE FEATURES

The XVME-976 offers the following features:

• One PC/104 and one PMC expansion module site

• On-board DC regulator to supply 3.3 volts to the PMC site

• Pin and socket connector scheme

• Optional PC/104-compatible modules for Ethernet, SCSI, serial and parallel expansion (available from Xycom)

• Optional PMC modules (available through third party) for ATM, FDDI and SCSI expansion

EXPANSION MODULES 

Minimal configuration for an expanded system includes:

• VMEbus processor module (the XVME-654 or XVME-655 with XVME-978/1 or 978/100)

• XVME-976 adapter module

• PC/104 or PMC expansion module

PC/104 EXPANSION MODULES 

The PC/104 expansion site on the XVME-976 allows PC/104 compatible modules to be used with XVME-654/655. These signals arrive from the host XVME-PC/AT. PC/104 expansion modules provide various I/O functions such as: Ethernet, SCSI, serial, parallel and flash disk.

Two types of PC/104 expansion modules can be used with the XVME-976 adapter module:

• Type A – Xycom PC/104 module with integral front panel included; mechanical dimensions of 4.010” x 5.091”

• Type B – Generic PC/104 module; mechanical dimensions of 3.550” x 3.775” (may require additional front panel kit)

PCI MEZZANINE CARD (PMC) EXPANSION MODULES 

The XVME-976 provides a PCI Mezzanine Card (PMC) site that allows the PCI functionality of the XVME-654 and -655 to be expanded. Electrically equivalent to the PCI bus standard, PMC has been adopted by VMEbus International Trade Association (VITA) and the VMEbus community to expand the PCI capability of the VMEbus processor modules. The PMC site on the XVME-976 supports PMC J2 I/O options.

PROCESSOR CONNECTION OPTIONS

The XVME-976 supports connections to the XVME-654 and XVME-655 VMEbus PC/AT processor modules.
