2.3.5 Software Installation Tips
Windows NT driver disk 2.00 and later
1. It is necessary to have a “Density Correction Lookup Table” installed to achieve accurate density
tracking. This file is located on the installation floppy disk. The file format is
“CLTXXXXX.DAT” where XXXXX is the serial number of the Reader. This file is installed in
the “C:\SystemRoot\SYSTEM32\DRIVERS” directory. Although more than one different file of
this format can be installed, the LSDT Control Panel needs to specify which file is to be used for
the particular digitizer in use.
2. The CAL Table matching the Serial Number of the unit must be installed in the
"C:\SystemRoot\SYSTEM32\DRIVERS" directory. The file is in the format
"CALXXXXX.DAT".
3. Installing the LSDT NT Software will create in the NT Control Panel a Device called LSDT.
4. The Digital Control Board uses three resources that need to be free. These are Segment Address,
IRQ, and Base I/O Address. One, two, or all of these resources can be changed if necessary.
These settings are hardware selectable on the DCB.
5. The LSDT Control Panel needs to match the DCB resource hardware settings. The default
resources are Segment Address D000, IRQ 5, and Base I/O 100. If these resources are used, it
isn’t necessary to change the LSDT Control Panel.
6. The most common alternate DCB resources are Segment Address D800, IRQ 7, and Base I/O
120.
7. From the LSDT Control Panel, select the CLT file matching the Serial Number of the Unit.
8. Select the appropriate CAL Table file in the LSDT Control Panel.
9. To verify the driver is installed properly, perform the following steps. Go to a COMMAND
prompt. Navigate to C:\LSDT32\TOOLS. Insert a plate. Run the SCANFILE.EXE program. At
the end of the scan the number of pixels per line and the total number of lines should be roughly
proportional to the film dimensions. As an example, a 35cm x 43cm plate at the default resolution
would be 2048 pixels per line and approximately 2500 total lines in the image. If the total number
of lines significantly differs from the proper ratio there is probably a Memory Segment conflict. If
the plate halts mid scan or doesn’t scan there is probably a Base I/O Address conflict. If the plate
goes all the way through the system without scanning there is probably an IRQ conflict.
Windows NT (prior to NT driver disk 2.00)
1. It is necessary to have a “Density Correction Lookup Table” installed to achieve accurate density
tracking. This file is located on the installation floppy disk. The file format is
“CLTXXXXX.DAT”. This file is installed in the “C:\SystemRoot\SYSTEM32\DRIVERS”

2. The CAL Table matching the Serial Number of the unit must be installed in the
"C:\SystemRoot\SYSTEM32\DRIVERS" directory. The file is in the format
"CALXXXXX.DAT".
3. Installing the LSDT NT Software will create in the NT Control Panel a Device called LSDT. The
LSDT Device can be set to start automatically or manually. Until the proper DCB resources are
found, it is recommended that the LSDT Device be set to Manual to prevent the PC from
locking when turned on.
