Introducing the Keithley IVI Driver for the 2268 Series of Programmable Power Supplies
The instrument driver provides access to the functionality of the
Keithley Series 2268 DC Power Supplies through a COM server which also complies
with the IVI specifications. This driver works in any development environment which
supports COM programming including Microsoft Visual Basic, Microsoft
Visual C++, Microsoft .NET, Keysight VEE Pro, National Instruments LabVIEW, and others.
The driver also works in IVI-C environements such as National Instruments LabWindows.

Supported Instruments
2268 Series

System Requirements: The driver installation will check for the
following requirements. If not found, the installer will either
abort, warn, or install the required component as appropriate.

Supported Operating Systems:
Windows 2000

Shared Components
Before this driver can be installed, your computer must already
have several components already installed. The easiest way to
to install these other components is by running the IVI Shared
Components installation package available from the IVI Foundation
as noted below. It installs all the items mentioned below.

IVI Shared Components version 2.2.1 or later.
The driver installer requires these components. They must be
installed before the driver installer can install the driver.

The IVI Shared Components installer is available from:

Any compliant implementation is acceptable. Typically, VISA-COM is
installed with VISA and other I/O library modules.

Additional Setup
.NET Framework
The .NET Framework itself is not required by this driver. If you
plan to use the driver with .NET, Service Pack 2 is required.
Download from:

The .NET Framework requires an interop assembly for a COM
server. A Primary Interop Assembly, along with an XML file for
IntelliSense is installed with the driver. The driver's PIA, along
with IVI PIAs are installed, by default, in:
:\Program Files\IVI Foundation\IVI\Bin\Primary Interop Assemblies

The PIA is also installed into the Global Assembly Cache (GAC) if
you have the .NET framework installed.

Start Menu Shortcuts
A shortcut to the driver help file is added to the Start Menu,
Programs, Keithley group. It contains "Getting
Started" information on using the driver in a variety of programming
environments as well as documentation on IVI and instrument specific
methods and properties.

You will also see shortcuts to the Readme file and any programming
examples for this driver.
