Preface
This manual describes the SBS Model 466-1 adapter that connects a Sun SBus
computer, such as a SPARCstation®, to a VMEbus system. It includes
information about the adapter's operation, installation, configuration, and
control registers.
To simplify installation and eliminate operation problems, SBS recommends
that you review this manual before beginning to install your new adapter
cards. Please pay close attention to the sections on card configuration and
adapter registers.
Chapter 1 provides an executive overview of the adapter, product
description, specifications, and requirements.
Chapter 2 gets you started with information about the adapter package
and cable.
Chapter 3 gives a detailed description of the SBus adapter card
configuration.
Chapter 4 describes VMEbus adapter card configuration.
Chapter 5 includes installation instructions.
Chapter 6 contains information about adapter registers accessed from the
SBus.
Chapter 7 provides information about adapter registers accessed from the
VMEbus.
Chapter 8 describes common procedures and programming sequences.
Chapter 9 provides suggestions and solutions for common problems with
setting up and using the adapter.
Appendix A is a glossary of terms used throughout this manual.

Appendix B describes VMEbus addressing.
Appendix C shows the differences between the Model 466 and Model
466-1 VMEbus adapter cards, including the default jumper settings and
jumper block changes.
Appendix D contains jumper configuration worksheets.
Important Notes:
Make sure you follow proper ESD handling procedures (refer to EIA-625,
ESD Association Handbook, or MIL-HDBK-263) when working cards
and components.
Be sure power is OFF before installing adapter cards.
