Thank you for purchasing this GPIB interface board and the NI-488.2 
software for Microsoft Windows 3.


We appreciate communicating with the people who use our products.  We are
also very interested in hearing about the applications you develop using
our products.  To make it easy for you to communicate with us, Appendix C
in the "NI-488.2 User Manual for Windows" contains forms for you
to complete.  Completing these forms before contacting National Instruments
facilitates communication.


NOTE ABOUT SOFTWARE CONFIGURATION UTILITY
-----------------------------------------

The Windows GPIB software configuration utility no longer resides in the
NI-488.2 GPIB Software group.  It is now a control panel applet accessible 
by running Control Panel in the Main group of the Program Manager.  The
utility, ibconf.cpl, resides in the Windows system directory. 


NOTE FOR RUNNING WIN32S GPIB APPLICATIONS
-----------------------------------------

The NI-488.2 software for Windows includes two dynamic link libraries (DLLs)
that make it possible to run 32-bit Windows GPIB applications. The two 
DLLs are called GPIB-32.DLL and GPIB-16.DLL. The 32-bit DLL (GPIB-32.DLL)
uses the Universal Thunking mechanism to communicate with the 16-bit DLL
(GPIB-16.DLL), and the 16-bit DLL talks directly to the standard 16-bit
GPIB DLL (GPIB.DLL) to get it to execute the appropriate NI-488.2 function.
For more information on the Universal Thunking mechanism, refer to Microsoft's 
"Win32s Programmer's Reference", chapter 4, "Universal Thunk".

When the NI-488.2 software for Windows is installed, these two DLLs are copied 
into the Windows SYSTEM directory.  You can use the Win32s Interactive
Control utility, a Win32s version of the Win16 Interactive Control
utility, to verify that the two DLLs are functioning properly.

In order to run the Win32s Interactive Control utility, you must have 
Microsoft Win32s support installed on your system. The Win32s Interactive
Control icon is the National Instruments eagle, like the Win16 Interactive
Control icon.

Anyone interested in developing 32-bit Windows applications should
contact National Instruments to obtain information about ordering the 
NI-488.2M Software for Windows NT package. It includes the language
interface and documentation necessary for developing 32-bit GPIB Windows
applications.


NOTE FOR LABVIEW USERS
----------------------

LabVIEW includes icons for WIBConf and WIBIC in the LABVIEW group when it
is installed. Please delete these two program items from the LABVIEW
group. The WIBConf program item in the LABVIEW group cannot be used to
configure the NI-488.2 software. The GPIB configuration utility is now a
control panel applet and must be run from the control panel. The
replacement for the WIBIC program item is the Win16 Interactive Control
program item in the NI-488.2 GPIB Software group.
