===============================================


BRIEF OVERVIEW ---

The application requires the device driver  "Port_io.sys" to be located in the
32-bit driver directory. For example c:\windows\system32\drivers. It also requires
the driver to be registered by entry into the Windows Registry. That can be done
automatically by executrion of  "Port_io.reg"  which can be done using the "RUN"
command from the start menu, or double clicking on the icon from with the windows
file manager "explorer". You must then  re-boot of the system for the changes to 
take effect. You can also make the entry manually if you have the means to do so. 
The dynamic link library  "Lab141NT.dll"  needs to be located in a path where 
LabView will look for it. Then when you run m141_nt.vi for the first time, you will need 
to tell LabView where the DLL is located once for each function that is called from
the VI. Once all of that is done then the VI should be ready to run.

Please read  "LabHelp.txt" for further information on operation of the VI.
