How do I properly run tabtest for my Summagraphics tablet?
To run tabtest, follow these steps:

1. Start from a DOS prompt. (If you have Windows95, see step 1a, for Windows98 see step 1b. If you have Windows NT, see step 1c.  Otherwise go to step 2.

   a.  For Windows 95 users. Reboot your computer. When the words "Starting Windows 95..." appear on the screen, press the F8 key. At the startup menu, select the "Safe Mode Command Prompt Only" option. Usually option 7. Go to Step 2.

   b.  For Windows98 users. Reboot your computer. After the "system beep" press the F8 key. Press it quickly or you will miss it. At the startup menu, select the "Safe Mode Command Prompt Only". Go to step 2.

   c.  For Windows NT users. If you have a DOS partition on your hard drive, reboot your machine and boot to it. If you do not have a DOS partition on your hard drive, it will be necessary to boot from a bootable DOS floppy diskette. Go to Step 2.

2. Insert the diskette containing the tabtest utility into your floppy drive and change to the corresponding DOS prompt.
3. Go to the directory on the floppy diskette containing the tabtest.exe file.
4. If your tablet is connected to COM 1, type <tabtest>. For COM 2 type <tabtest /2>.
5. When the tabtest screen appears, you will see 3 columns on the left side of the screen. S/W  X  Y
6. If you are using a 4-button cursor or a stylus, you will see coordinates scrolling on the screen when the pointing device is in proximity with the surface of the tablet. If you are using a 16-button cursor, you will need to press the following keys, in order,  to be able to view the coordinates: <F3, g, ESC>

How do I program the buttons on my pointing device for use in AutoCAD?
Autodesk has step-by-step instructions for programming button assignments on their website located in the Technical Solutions & FAQs section.

How do I set up my Summagraphics tablet to work with AutoCAD Release 2000?
Before using these instructions, the digitizer should be working on the Windows desktop, as a pointer, using the current tablet driver:

1.  In AutoCAD 2000, pick the Tools pull-down menu, then pick Options.

2.  Pick the System tab.  In the area called "Current Pointing Device", select Wintab Compatible Digitizer ADI 4.2 - by Autodesk.

How do I get AutoCAD 14 or 2000 to access both screens with my Dual Monitors?
Before using these instructions, make sure you are using TabletWorks Wintab™ Driver Version 5.2 (or higher) or 6.1 (or higher), which support Dual Monitors.

1. Open the TabletWorks Control Panel.

2. Enter the Tablet or Mapping screen (depending on which version of the Wintab™ driver you are using).

3. Select Enable Mapping (make sure the "WYPIWYG" pointing mode is selected). Now select Apply.

Setting the TabletWorks Control panel up this way will allow you to use the DrawingBoard III in absolute mode on both screens in AutoCAD.

Why does my digitizer work only after I remove my comports from Windows 98 and restart my computer?
When the comports are removed from Windows and the computer is restarted, Windows will detect the comports and reinstall the comport controllers. At this point Windows has not started the Power Management feature for the comports, thus the tablet will work normally. Once the computer has been restarted again, the tablet will quit working. 

This is an issue that has just recently developed with a number of new high speed motherboards. We are taking measures to fix this issue with our next TabletWorks Driver version. For assistance with this issue, please contact our Technical Support Department at: (480) 443-2214.

1. Open the Control Panels folder.
2. Locate the TabletWorks Control Panel and drag it to the trash.
3. Open the Preferences folder.
4. Locate the TabletWorks Prefs file and drag it to the trash. (Note:  This file will not exist if no custom settings have been made.)
5. Empty the Trash Can.
6.Restart your computer.
