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.
To verify the driver is installed properly, perform the following steps. Go to a COMMAND prompt.
Navigate to C:\NTLSDT\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.

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 on the C:\ root directory. There can be only one file of
this format installed at one time. Also, the file needs to match the Serial Number of the digitizer.
2. The CAL Table matching the Serial Number of the unit must be installed in C:\ root directory.
The file is in the format "CALXXXXX.DAT".
3. The TSR driver, LSDTVXXX.COM, needs to be loaded for the digitizer to operate. The driver is
located in the C:\LSDT\TOOLS directory.

5. The TSR driver command line 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 TSR driver command line.
