About this guide

This Integrator’s Guide provides the information need ed to use the Kodak Digital Science Document Scanner 9500 .

You should be familiar with the operation of the scanner. If you are not, refer the Appendix B, Reference Materials for a complete listing of available publications.

In addition to this information, the Integrator’s Guide contains the following chapters:

Chapter 2, Scanning Concepts, provides an overview of the scanning process.

Chapter 3, Image Headers, provides an overview of the information generated during the scanning process.

Chapter 4, Scanner-host Communications, describes the communications between the scanner and the host system.

Chapter 5, The SCSI Interface, describes the SCSI bus, SCSI commands, SCSI status and message responses and SCSI conformance.

Chapter 6, Scanner-unique Commands, describes the commands used to control the scanner from the host computer.

Chapter 7, The Diagnostic Interface (J45/COIN3), describes the communications between the scanner and an RS-232 terminal that can be used as an interface to receive diagnostic information.

Appendix A, Glossary, provides a list of commonly used terms and definitions pertaining to the scanning environment.

Appendix B, Reference Materials, provides a list of other available publications from Kodak supporting the Document Scanner 9500.

Appendix C, Assigning Image Addresses, defines the fields required for a valid image address.

Appendix D, Image Processing Parameter Defaults, provides default parameter values and recommended image processing parameters.

Appendix E, Image Processing, provides an overview of the image processing capabilities of the scanner /microimager, which are controlled by the host computer and methods for evaluating digitally scanned images.
