The Keithley2280 IVI-COM/IVI-C driver conforms to the IVI driver standards and specifications. The help file included with the driver contains the detailed driver functionality description and programming information.
This readme file contains additional information for the user.
The driver uses the services provided by IVI Shared Components (provided by IVI Foundation) and VISA.
The driver can be used with GPIB or LAN or USB.

Supported Instruments
Model 2280S-32-6
Model 2280S-60-3
Model 2281S-20-6

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 XP
Windows Vista
Windows 7
Windows 8

Shared Components
Before this driver can be installed, your computer must already
have the IVI Shared Components installed.

Minimal IVI Version: 2.3

The IVI Shared Components installer is available from:

The following implementations of VISA are compliant with this driver: NI-VISA?, AGILENT IO Libraries Suite?.
The Keithley I/O Layer supplies a NI-VISA? runtime. Downloads are available at www.keithley.com/support or you may follow the link below:

Additional Setup
.NET Framework
The .NET Framework itself is not required by this driver. If you
plan to use the driver with .NET, the minimal .NET framework version is 2.0.

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.

Help File
The help file (Keithley2280.chm) is located in the directory:
:\Program Files\IVI Foundation\IVI\Drivers\ke2280

The driver installs few examples written in C Sharp .NET and C++. Examples are located in the directory:
:\Program Files\IVI Foundation\IVI\Drivers\ke2280\Examples
