Agilent 34405 IVI-COM Driver Read Me

**** Read Me First ****

April 29, 2006

Introducing the Agilent IVI-COM Driver for the 34405A Digital Multimeters
The instrument driver provides access to the functionality of the
Agilent 34405A DMM 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, Agilent VEE Pro, National Instruments LabView,
National Instruments LabWindows, and others.

Supported Instruments

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 NT® 4.0 (SP6 or later)
Windows 2000
Windows XP

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 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:

To install, open or run the file: IviSharedComponents.msi

If the driver installer exhibits problems with installing the IVI
Shared Components, find the program IviSharedComponents.msi and
Run the program. It is able to install many of the required system
components, including Windows Installer 2.0.

Windows Installer
Version 2.0 or later. The IVISharedComponents.exe program will
install version 2.0 of the Windows installer.
It is also available from:
For Win98/Me:
For WinNt4/2000/XP:

Microsoft XML 4.0
The Configuration Server, an IVI Shared Component, uses Microsoft's
XML 4.0 parser. The IVI Shared Components will install the XML 4.0
parser. You can download the parser and its associated SDK from:
Enter "xml 4.0" as keywords.

Microsoft HTML Help Viewer (Win98, WinNT) Version 1.32 or later
The driver will install without the help viewer, but you will not
be able to use the help file for the driver. You can download the
help viewer from:
Enter "html help workshop" as keywords

MS Windows® Script
Typically, wscript.exe is installed as part of the operating system
or with Internet Explorer. If you see an error about wscript.exe,
you need to install the Windows Script.
Download from:
Enter "windows script" as keywords. Use the one appropriate for
your Operating System.

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

If you are using Agilent Technologies' VISA-COM, use
version or later. The latest version of Agilent's IO
Libraries includes the required version of VISA-COM.

If you are using NI VISA version 3.3 or earlier, you may need to manually register the Basic Formatted I/O
component. This file is called BasFrmIO.dll and is located in C:\VXIPnP\VisaCom directory. If you installed
VISA to an alternate location, then the component will be located in the VisaCom subdirectory of that directory.

If you are using Agilent Technologies' IO Libraries, use version
M.01.01.04 or later. You can download the latest version from:

If you are using National Instruments I/O libraries, use NI-VISA
version 3.0.1 or later and NI-488.2 version 2.2 or later.

Sending commands directly to the instrument (bypassing the driver)
via Direct IO using the System.IO interface will not work with Agilent
IO Libraries prior to Agilent IO Libraries Suite 14.0.

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\Bin\Primary Interop Assemblies

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

If you install the .NET framework later, you can use the file:
:\Program Files\IVI\Drivers\Agilent34410\DotNet.bat
to put the driver's PIA into the GAC and properly register it.

Start Menu Shortcuts
A shortcut to the driver help file is added to the Start Menu,
Programs, IVI, Agilent34405 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.

Help Files
The help file (Agilent34405.chm) is located in the directory:
:\Program Files\IVI\Drivers\Agilent34405

MSI Installer
The installation package for the driver is distributed as an MSI 2.0
file. You can install the driver by double-clicking on the file.
This operation actually runs:
msiexec /i Agilent34405.msi

You can run msiexec from a command prompt and utilize its many
command line options. There are no public properties which can be
set from the command line.

This driver can be uninstalled like any other software from the
Control Panel using "Add or Remove Programs".

To uninstall the IVI Shared Components you must use the IVI Cleanup
Utility available from the IVI Foundation at:

Note: All IVI-COM drivers require the IVI Shared Components to
function. To completely remove IVI components from your computer,
uninstall all drivers then run the IVI Cleanup Utility. This utility
does not remove any IVI drivers.

Using a New Version of the Driver
New versions of this Agilent IVI-COM driver may have a new

If you use the version dependent ProgId in CoCreateInstance,
you will need to modify and recompile your code to use the
new ProgID once you upgrade to the next version of the driver.
Doing a side-by-side installation of the driver to use multiple
versions of the driver is not supported. If you need to go back
to an older version of the driver, you need to uninstall the later
version and install the older version.

If you use the version independent ProgId in CoCreateInstance,
you will not need to modify and recompile your code. The new
version of the driver has been tested to be backwards compatible
with previous versions.

To access the new functionality in a new version of the driver
you will need to use the latest numbered IAgilent[n]
interface rather than the IAgilent interface. The
IAgilent[n]. property will return a pointer
to the new IAgilent[n] interface. The
IAgilentN490x[n] interface contains the methods and
properties for the new functionality. The new interfaces were
introduced rather than modifying the existing interfaces for
backwards compatibility. The interfaces that were previously
shipped have not been changed.

Known Issues
If you are using NI VISA version 3.3 or earlier, you may need to manually register the Basic Formatted I/O
component. This file is called BasFrmIO.dll and is located in C:\VXIPnP\VisaCom directory. If you installed
VISA to an alternate location, then the component will be located in the VisaCom subdirectory of that directory.

NOTE: For VEE revisions VEE 7.51 or earlier, the IVI-COM driver button under the
IO -> Instrument Manager does not automatically work with this driver. You
must manually select this driver by doing the following steps:

1. Launch Vee 7.51

2. Open Instrument Manager.

3. Click Find Instrument under the Auto Discovery tab.

4. Select the 34405 in the list that comes up.

5. The IVI-COM driver button is greyed out.

6. Click on Properties(Under Instruments tab)-->Click on “Advanced…” button in the

window that comes up.

7. Select the last tab on the window that comes up (IVI-COM Driver).

8. Select the Agilent34405 driver from the drop down list.

9. Click on OK & Come to the main window . The IVI-COM driver button should now

be active.
