Setup 3xxxx tablet with AutoCAD 12 for DOS

A.  Set the tablet soft switches to GTCO settings.

     1.   Use the pointing device to click on the CONFIG/EXIT key on the tablet menu strip using the pick button on the
           pointing device.  The CONFIGURATION light on the digitizer should turn on.

     2.   Click on the Bank A key.

     3.   As you place the pointing device on each button of the tablet 1 through 18, the POWER light will be either on or
          off. You can toggle the setting of any button by pressing the pick button.   The settings should be as follows:

           Bank A-1  1  0  0  0  1  1  1  1  1  0   1  0  1  1  1  0  1

           Bank B-0  0  1  1  0  0  0  0  0  0  0   0  0  0  0  0  0  1

           (1=POWER light on      0=POWER light off)

     4.   Click on the SAVE DEFAULT key to save these settings as the power-on default.

     5.   Click on the CONFIG/EXIT key to EXIT the CONFIGURATION.  The CONFIGURATION light on the digitizer
           should turn off.

B.   Reconfigure AutoCAD for the CalComp Driver

     1.   Start AutoCAD and type "CONFIG" at the Command Line.

     2.   Choose "Configure Digitizer".

     3.   Do you want to select a different one? [Y]

     4.   Select "CalComp Digitizer Series ADI 4.2 - by CalComp" from the AutoCAD Digitizer Configuration menu.

     5.  You will be prompted to enter the digitizer model, the size of the tablet, number of buttons on the cursor, and the
          COM port the tablet is connected to.   AutoCad will then prompt you to choose Polling or Interrupt mode.  If the
          system you are using is a 486/66 or Pentium system, choose Polling.  With a 386, it will depend on the system.
          Try both Polling and Interrupt to define which works best with your system.

     6.   Type "0" to Exit

     7.   Keep configuration changes.  [Y]

     8.   Enter the drawing editor by opening or creating a drawing.

        a.  With the Polling option, there could be possible crosshairs snagging or sticking  in Autocad.  This would  be a
             fraction of a second delay and happen about every 20 seconds.   Changing the Vscan  rate easily resolves this
             situation.  To make the changes you will need to be in the ACADR12\DOS  DIRECTORY and type:

            CFIG386  ACAD   -VSCAN   XXXXXX. 

            The formula to calculate the "XXXXXX" rate is as follows:

            Pentium 200:    20000   x Memory  x 11  
            Pentium 166:    20000   x Memory  x 10
            Pentium 150:   20000   x Memory  x 9
            Pentium 133:    20000   x Memory  x 8
            Pentium 120:    20000   x Memory  x 7
            Pentium 100:    20000   x Memory  x 6
            Pentium 90:     20000   x Memory  x 5
            Pentium 66:     20000   x Memory  x 4
            Pentium 60:     20000   x Memory  x 4
            486:                20000   x Memory x   3
            386:                20000   x Memory x   2

C.   If the Digitizing Crosshairs Don't Appear

     1.   If you use a 16-Button Puck, try selecting the GTCO driver in the CONFIGURATION.

          a.   Follow all steps in section A and steps C.1 through C.3 above.

          b.   Select the GTCO Driver from the driver options list.

          c.   Answer the driver questions about your digitizer model.

          d.   Type "0" to Exit

          e.   Keep configuration changes.  [Y]

          f.   Enter the drawing editor by opening or creating a drawing.

     2.   If you use a 4-Button Puck, try selecting the 9100 driver in the CONFIGURATION.

          a.   Follow all steps from A.1 through A.3 above.

          b.   Use the following settings to set the digitizer to a CalComp 9100       

               Bank A-  1  1  0  0  0  1  1  1  1  1   0  0  0  1  0  0  0  0

               Bank B-  0  0  1  0  0  1  0  0  0  0   0  0  0  0  0  0  0  1

              (1=POWER light on      0=POWER light off)

          c.   Follow Steps A.4 through A.5 and C.1 through C.3

          d.   Select the CalComp 9100 Driver from the driver options list.

          e.   Answer the driver questions about your digitizer model.

          f.   Type "0" to Exit

          g.   Keep configuration changes.  [Y]

          h.   Enter the drawing editor by opening or creating a drawing.
