To install the VXI

plug&play

libraries

System Requirements (Microsoft Windows)

•

An IBM compatible personal computer with either Microsoft Windows 95 or later or
Microsoft Windows NT. (With either Windows OS, use the VXI

plug&play

library)

•

Additional hardware and software to connect the IBM compatible computer to a VXI
mainframe.

•

Software is supplied on CD-ROM.

System Requirements (HP-UX 10.20)

•

One of the following workstations:

q

An HP V743 VXI-embedded workstation.

q

A stand-alone HP Series 700 workstation with an Agilent/HP E1489I EISA-to-MXIbus
card and an Agilent/HP E1482B VXI-MXI Bus Extender.

•

Software is supplied on CD-ROM, so a CD-ROM drive is needed

•

HP-UX Version 10.20. This version of HP-UX can use either the C-language library
or the VXI

plug&play

library.

•

SICL/VISA (product number E2091E, version E.01.01 or later).

VT1432A Software Distribution

The VT1432A distribution (software) is shipped on CD-ROM with the VT1433B
module. This software works with the VT1432A, VT1433B and VT1434A
modules. This distribution includes the the VT1432A C-Language Host Interface
Library for HP-UX, the VT1432A VXI

plug&play

Host Interface library for

HP-UX, Windows 95 or later and Windows NT with associated examples and
manual pages.
