Read Me for LabVIEW Driver for the Fluke 2680 Series

"FL268x" is a LabVIEW 6.1 driver for the Fluke 2680A Data Acquisition System
and 2686A Data Logging System.  This "FL268x" driver also supports the Fluke
NetDAQ model 2640A and 2645A Data Acquisition Units.

The "FL268x" driver was written for LabVIEW 6.1 on Windows XP, Windows 2000,
Windows NT 4.0 or Windows 98.  Windows NT 4.0 requires WinNT Service Pack 6; 
Windows 2000 Service Pack 3 is recommended for Windows 2000. 

To install this driver, extract the contents of this ZIP archive (with the
path) to the "instr.lib" directory of your LabVIEW installation (typically
"C:\Program Files\National Instruments\LabVIEW 6.1\instr.lib").

It also is necessary to install the Communication Toolbox DLL file (Windows
Dynamic Link Library) used by the driver.  To do this, run the installation 
file "NTool32_DLL.exe" to automatically install the Toolbox DLL. 


Driver Information:

The "FL268x" LabVIEW instrument driver consists of a ZIP archive containing
the driver sources (LLB and MNU files).  In addition, the instrument driver
documentation is included in compressed HTML format (Windows CHM help file)
stored together with the driver sources.  Each VI's help is linked to the
section in the "fl268x.chm" file that describes all the features of the VI.

This "FL268x" driver for the Fluke 2680 Series units is based on "Ntool32.dll",
a Windows Dynamic Link Library file that communicates with the Data Acquisition
system over an Ethernet interface using TCP/IP network protocol.  "FL268x" is a
DLL wrapper of "Ntool32.dll" written in LabVIEW 6.1.  It does the type casting
and data handling needed to port the C data structures and function calls from
"Ntool32.dll" to the LabVIEW development environment.  Note that "Ntool32.dll"
must be properly installed in the Windows PC for the "FL268x" driver to work.

"FL268x" provides a LabVIEW VI for each function contained in "Ntool32.dll";
these direct function VIs have names that begin with the prefix "flk".  The
"FL268x" driver also includes additional advanced data manipulation VI's to
simplify handling of configuration and scan data structures used by the DLL.
"Ntool32.dll" provides a function call for each command that can be sent to
the 2680 Series or NetDAQ units; the DLL has added functions to support its
operation, e.g. for library initialization and communication configuration.

The "FL268x" driver supports both the 2680 Series and NetDAQ (264x) models.
Many functions are the same for all models, but some have separate functions
for the 2680 Series and NetDAQ.  As a simple rule of thumb, if a function VI
has the letters "Jr" in its name, that function is for the 2680 Series and
there is another one for the NetDAQ models; otherwise, the same function VI
is used for all models.
For example, there are function VI's named "flkJrScansGet", "flkScansGet" and
"flkScansEnable".  Since "flkJrScansGet" contains the letters "Jr", it is for
the 2680 Series only and the similar function named "flkScansGet" is used for
NetDAQ.  However, since there is no "Jr" in "flkScansEnable" that function VI
is used for all of the models.
