XVME-976 Adapter 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; me-
chanical 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 In-
ternational Trade Association (VITA) and the VMEbus community to ex-
pand 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.
Installing the XVME-976 on an XVME-654
The adapter module connects directly to the XVME-654 via Interboard Con-
nectors 1 and 2. Additional equipment (supplied with the XVME-976)
needed to complete the connection is as follows:
•
Two corner standoffs
•
Two pairs of standoff screws
Installing the XVME-976 to the host XVME-654 Processor
Module
1. Follow procedures for the prevention of static discharge to prevent dam-
age to the circuitry of the modules.
2. Disconnect all power sources.
3. Loosen the screws on the front panel of the XVME-654 processor mod-
ule.
4. Remove the XVME-654 from the VME backplane, as follows:
1-2
Gently pull on the face plate until it slides out of the chassis
