The I-2000 scanner interface boards will work on AT Bus machines.
Generally speaking, installing an I-2000 board is a four-step procedure:

• physically installing the board in your computer;
• connecting the scanner to your computer;
• installing the software drivers;
• testing the completed installation;

Steps 1 and 2 are described in more details in chapter 4, while steps 3 an 4 are covered in chapter 5.

Warning!

The present manual is designed to install and test hardware components and drivers using Dunord supplied scan utilities. Installation procedures for software packages are either included with the installation procedure of the package, or included in the README.TXT file that can be found in the main directory of the driver diskette.

Models designed for an AT bus use four I/O addresses, one Direct Memory Access (DMA) channel and one hardware interrupt level (IRQ). Make sure that you have all pertinent information regarding other interfaces installed in your computer. This will be needed if any conflict is detected using default values.
Once your board has been installed and is operational with Dunord's supplied utilities, observe any specific instructions about loading the Windows drivers that are sometimes given in the installation section of the application that will use the scanner.

Dunord's I-2000 family of scanner interface boards rely entirely on the machine onto which they are installed to store the scanned image, and to enhance and compress it. This means that the machine must have enough memory to store the uncompressed image, and that the faster the processor, the more throughput can be obtained from the application.

The minimal system requirements are as follows:

• MS-DOS 5.0 and Windows 3.1, or Windows 95;
• A 386 or faster CPU.
• One available serial port.
• A scanner compatible with the interface model.
• The extended memory manager (xms) must be installed in CONFIG.SYS (DEVICE=HIMEM.SYS)
• Enough memory to store the scanned image. The exact amount depends on document size and resolution.

All memory requirements are given in Kbytes

4. Installing the interface

* The I-2000 are static sensitive devices

Before taking the card out of the plastic packing, make sure that you ground yourself by touching the computer's metal back or side panel

1. Set the dip switches of the I-2000 according to your system needs. Most systems will work fine with the factory set defaults.
The interface uses four consecutive I/O addresses (3xC to 3xF). The switch block located on the board allows you to change the middle digit of the address range (the x in 3xC). Sixteen (16) different I/O address ranges can be used. Some of those, however, will conflict with other devices on your computer (i.e. COM1 uses 3F8 to 3FF). The following table gives four address range that are normally free on many systems:

The ON position is indicated on the switch block

2. Unplug the computer.
3. Remove the screw holding the cover of an unused 16 bit expansion slot and save the screw for later use
4. Hold the card at each top corner and push down firmly to seat the card.
5. Fasten the card's metal retaining bracket with the screw you removed in step 3.
6. Replace the computer's cover.
7. Connect the scanner video cable from the scanner SC2 plug to the I-2000 connector.
8. Connect the serial cable from the scanner SC1 plug to your available PC serial port.
If your port has a 25 pin connector, use the 9-to-25 expander shipped with the card. Make sure that you use only this expander since other types might lack some connections required for proper communication with the scanner.
9. Turn on your scanner and your computer.

Dunord supplies a comprehensive set of Windows drivers for imaging applications. This set contains :

• Dunord Windows driver;
• ISIS driver;
• TWAIN driver;
• TMS driver.

The ISIS, TWAIN and TMS drivers are industry standard and interface with Dunord's basic Windows drivers. ISIS and TWAIN are included on the driver floppy shipped with the I-2000 Scanner Interface board, while the TMS driver is normally supplied with the TMS application.
The ISIS and TWAIN drivers can be installed by the installation program, however, additional steps may be required depending on the application. Consult the README, or your application installation manual for specific instructions.

5.1 Installing Dunord's Windows drivers

To install the drivers, select RUN from the FILE menu of the Windows Program Manager, type : a:\setup, and click on the Install button. The Setup program will copy some files to your WINDOWS and WINDOWS\SYSTEM directory. The Setup program, S2F and the install log will be copied to C:\DUNORD (or any other directory that you might specify). It will also create a group called DUNORD where the SETUP, README and S2F icons will be copied.
After the drivers files have been installed, the Setup program will display a window that allows you to modify the hardare parameters (ComPort, I/O address, IRQ and DMA), change them or accept the defaul values.
When this is complete, make sure that you restart Windows for modifications to take effect before trying to make a scan.

5.2 Changing hardware parameters

To change hardare parameters, start the Setup program and click on the Setup Card button. Change parameters and exit the Setup program.

5.3 Installing a new driver

If you want to add a driver (like ISIS or TWAIN), or have received a new version of drivers, start the Setup program and click on the Install button. Select the drivers you want to install (de-select the installation of Dunord driver if you are adding ISIS or TWAIN) and continue the installation.
When the install program asks you for the path, be sure to specify the location where the driver files are located. This is either the diskette or the directory where you have extracted the files you obtained from our Web site

5.4 Uninstalling drivers

To uninstall Dunord drivers, start the Setup program and click on the Uninstall button. Confirm that you want to remove the drivers and the Setup program will delete all files and remove modifications that have been made to your SYSTEM.INI file. If the drivers have not been installed, or file INSTALL.LOG has been deleted or moved, the Uninstall button will not be displayed.
The Setup program relies on file INSTALL.LOG to know which files have been copied and where they are located. This file is updated every time you make a change to Dunord drivers using the Setup program. It must reside in the same directory as the Setup program. If the file has been destroyed or moved the Setup program will not be able to remove drivers automatically.
If some files previously installed by the Setup program have been moved or destroyed, it will display a list of the missing files and ask you if it shoud procede to delete the rest. It is your responsibility to find and delete the missing files.

5.5 Testing your installation

Once your installation is complete, you should test it using Dunord S2F utility program. Refer to the S2F user's guide for installation procedure and utilization. Chapter 7 of the present document gives a list of symptoms, probable causes as well as remedies to help you solve any conflict detected when trying to scan.

5.6 Windows 3.1x considerations

Smartdrive

The default values for Smartdrive use 2 megabytes of memory. On machines having a limited amount of memory, it might be preferable to decrease the buffer size to 512, or even 384 Kbytes. This is done by modifying the Smartdrive line of the AUTOEXEC.BAT file to:

<path>SMARTDRV.EXE 512 512

Use 384 instead of 512 if you want smaller buffer. There will be a slight decrease in performance in disk operations.

EMM386

If you do not explicitely define parameters for EMM386 in your CONFIG.SYS, Windows will load it with its own default value. To make sure that no problem is encountered with extended memory, add the following line (or modify the existing one) to:

DEVICE=<path>EMM386.EXE noems

Enhanced mode

Make sure that Windows is operating in Enhanced mode, and that the COM port used has been set to Never Warn. You can do this in the 386 Enhanced utility of the Control Panel.

Machine with large memory

If your computer has more than 16 megabytes of memory, it is necessary to reserve memory in the first 16 megs because AT Bus cards cannot access memory over that 16 megs boundary. The Setup program will add the following lines to your Windows SYSTEM.INI file

[dunord]
PrivateMemory=3950

This will reserve close to 4 megs of memory in the lower 16 megs. It is enough to allow you to scan Double Letter or A3 documents at 400 dpi. You can reduce the amount of memory to the maximum required by your application. See Memory Requirements table is chapter 3.

5.7 Windows 95 considerations

In Windows 95, make sure that the resources used are identified to the dunord board in the following manner.
In Control Panel, choose System, then Device Manager. Then, click Computer and open the Reserve Ressources TAB.
Add a ressource reservation for the 3 following types (set the values to the ones that have been identified in Setup Card of the Setup program.

This will ensure that no other device is be able to use the same settings.

5.8 DOS considerations

The installation procedure for the DOS driver in included in the README.
