VXI-AT2022/NI-VXI SCO UNIX Getting Started

Chapter 1
Introduction

This chapter describes the VXI-AT2022 interface kit and lists the contents of your kit and optional
equipment.

The VXI-AT2022 is an interface kit that links any IBM Personal Computer AT or compatible
computer (hereafter referred to as the PC AT) directly to the VXIbus. A PC AT equipped with a
VXI-AT2022 can function as a VXI Commander and Resource Manager. The VXI-AT2022 makes
the PC AT appear as though it were plugged directly into the VXI backplane as an embedded CPU
VXI module.

What Your Kit Should Contain

Your kit should contain the following components:
