On the next version of this CD,  we'll automate this process, although it is extremely simple. Just follow this procedure:

1. Make a subdirectory off your C: drive to contain the executable program DIGISEM.EXE or VITSCAN.EXE.
2. Navigate to the DIGISEM.EXE or VITSCAN.EXE program in the 'EXES' directory of this CD.
3. Copy DIGISEM or VITSCAN to the directory created in step 1. 

Or, do step 1, and FTP into it from one of these links: VITSCAN3 or DIGISEM3

 That's all that's required, but you may wish to navigate into the directory and left click on the EXE file to create a shortcut to it.  It is very handy to have a shortcut on the Windows desktop.  Additionally, you may wish to assign an icon to the shortcut.  The way our image collection software uses Windows resources causes it to be labeled as an MS-DOS program, so a more intuitive icon is nice. 

The software is now installed, you can return to the main Installation menu or proceed to the next step: Brightness Setup.

Uninstalling or moving our software:

Please not that our software does not modify any Windows .INI files, the program registry or any other file on your PC.  To remove our image collection software, simply delete it.  To install an update, rename your current version (if you wish to keep it) and copy the update into the directory you select.  We recommend that the directory be right off the rood directory, an example would be 'C:\SEMCONTROL'.

To move the image collection software to a new directory, just move everything in the directory with the EXE file.  5 small files are created by the EXE, and they contain necessary program and calibration parameters.   

Unnecessary details:

However, if you wish to know more of the details, read on.......

Note that you may have either VITSCAN..EXE OR DIGISEM3.EXE.  These programs are virtually identical.  In the rest of this documentation, we will refer to VITSCAN or DIGISEM simply as the 'Image capture' or 'image collection' software.  When you run the image capture software for the first time, it will create 5 very small additional files in the directory it's installed in. 

File	Approximate Size  (in bytes)
VITSCAN.EXE	266,336
FLYBACK.CFG	9
LASTUSER.CFG	29
LUTPARM8.DEF	175
USERTAGS.SAV	532
DBCMODE.CFG	18

What these files do:

	VITSCAN (or DIGISEM) - Executable file.  This is the file that controls the DRV-2000 interface and collects images.  The other 5 files  files contain various forms of data which must be saved from session to session.
	FLYBACK.CFG - retains a coefficient that allows the beam flyback period to be controlled by the software.  The hysteresis characteristics of each model of SEM are different.  By allowing just the minimum amount of compensation of a SEM by SEM  basis, faster scanning rates are possible for customers who have a low hysteresis deflection system.
	LASTUSER.CFG - This file is not currently in use.  It originally contained data about the last users dwell times, brightness settings, etc.
	LUTPARM8.DEF - This file contains various data which must be saved from one session to the next, such as the last image directory, the 'magic calibration number', signal inversion settings, etc.
	USERTAGS.SAV - This file retains the TIFF header information entered for the last image collected.
	DBCMODE.CFG  - This file contains the 'mode 0' or 'mode 1' designation.  It must be modified using an ASCII editor such as notepad at the initial installation.

Additionally, at the customers request, we can supply a special edition of VITSCAN or DIGISEM to output various other database delimited image data.   

Here is the general structure of the LUTPARM8.DEF file:

C:

The configuration files store program parameters. Specifically, lines 1 and 2 are the constants used in a Y = mX +b contrast correction. Line 1 is the m's for the 6 input channels; SE. BSE, X-ray 1 - 4. Line two is the b's. Line 3 is the X and Y resolutions for image collection. Line 4 is no longer used but is retained for future use.  Line 5 saves the signal invert status of the SE and BSE channels.  It also contains the invert status of the X and Y scans Line 6 is the width of a field of view (as digitized by the PC) at 1000X on the SEM. This value can be calculated by measuring an image of a digitized standard. It is critical in determining the proper sizes for all micron bars displayed by DIGISEM. The line 9 is the working image storage subdirectory. Line 10 is the temporary image storage directory, and should be set to C:.

If you would like detailed information about the other configuration files for a legitimate purpose, we would be happy to release it.
