Unzip all files in same directory. VB141_NT.DLL must be placed in application directory The file "PORT_IO.SYS " must be located in 32-bit driver directory, for example c:\windows\System32\Drivers. The file "PORT_IO.REG" must be run once to make required entries in Registry for loading of PORT_IO.SYS. That can be done by simply double-clicking on the file, or RUN from the program manager. Required entries can also be done manually using utility such as Regedit.exe. After registry entries are made you must reboot machine before attempting to run the application. Run VB141_NT.EXE, or open VB6_M14.VBW and run from within project workspace. Default configuration for single channel scan at rate approaching 1000 hertz. Digital input is available anytime, and is also autmatically updated whenever the "Get one Conversion" button is pressed or with each scan in scanning mode. Optically isolated outputs are controlled using the "ext-chan" combo box. See end of VB141.CFG configuration file for explanation of the lines in that file. If you must edit that file, do so with care and be sure to keep a backup of the original. Debugging is set to 0 by default. Valid debug levels are 0-4. The higher value writes more information to "141debug.txt" from DLL. Last Updated 6-6-2000
