Chapter 1 - Introduction
Overview
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 XVME-
655 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 pro-
vide 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 par-
allel 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

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:
•Gently pull on the face plate until it slides out of the chassis

Chapter 1 – Introduction
1-3
5. Place the XVME-654 on a static-free surface with the Interboard con-
nectors facing up.
6. Align interboard connectors 1 and 2 on the XVME-976 with the same
connectors on the XVME-654.
7. Gently press the two boards together. Do not bend or twist the XVME-
976.
8. Add standoffs (2) and standoff screws (2 pairs) as illustrated in Figure 1-
1.
Figure 1-1. Installing XVME-976 onto XVME-654
9. Clear two adjacent card cage slots.
10. Align the two connected modules (with the XVME-976 on the right) on
the card guides in the slots.
11. Gently push the modules to the rear of the chassis until the P1 and P2
connectors engage.
12. Tighten the screws on the front panel of the XVME-654 processor mod-
ule to secure the connected modules into place. The installation is com-
plete.

Installing the XVME-976 on an XVME-655
The XVME-976 connects to the XVME-655 indirectly through an XVME-
978 expansion module. Additional equipment needed to complete the con-
nection is as follows:
•Two long standoffs, and either the
•XVME-978/1 Ethernet expansion module or the
•XVME-978/100 transition module (if Ethernet functionality is not
needed)
Installing the XVME-976 to the Host XVME-655 Processor
Module
Note
This procedure assumes the XVME-978 has been installed onto
the XVME-655 processor module. Instructions for installing the
XVME-978 onto the XVME-655 can be found in the XVME-
655 manual.
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-655 processor mod-
ule.
4. Remove the XVME-655 (with XVME-978 connected) from the VME
backplane, as follows:
•Gently pull on the face plate until it slides out of the chassis
5. Place the boards on a static-free surface with the XVME-978 on top.
6. Align interboard connectors 1 and 2 on the XVME-976 with the inter-
board connectors on the XVME-978 module.
7. Gently press the two boards together. Do not bend or twist the XVME-
976.
8. Add standoffs (2) and standoff screws (2 pairs) as illustrated in Figure 1-
2.
