Setup 25xxx Tablet with AutoCAD 13 for DOS

A.  Set Tablet Menu Settings to "AutoCAD as GTCO DP5"  from the 2500 User's Manual

    1.  Refer to the "SETTING THE SOFT SWITCHES" in your 2500 User's Manual for instructions on setting up the
         tablet for "AutoCAD as GTCO WITH GTCO MICRO DIGI-PAD EMULATION."

    2.  Following are the menu settings required to enable your digitizer to operate correctly:

        Bank 1-  00000001             Bank 4-  00110100
        Bank 2-  11001000             Bank 5-  01010100
        Bank 3-  01110111             Bank 6-  00001000

       (1 =  Power Light is  ON  0 = Power Light is  OFF) 
   
     3.  To change the menu settings:
  
         a.  Place the cursor on the "BANK" block.

         b.  Select the block by pressing the "0" button. The indicator light will show which of the 8 banks is currently
              active.

         c.  Select the block whose number corresponds to the number of the bank you wish to set.

         d.  Select the "SETUP" block.  The BANK indicator will go off and the SETUP indicator will go on.  The lights in
              the eight numbered blocks now indicate the status of the switches in that bank. 

         e.  The Pick 0 button will toggle the light of each block to the setting you wish.

         f.  Repeat steps "a" through "e" for each bank requiring changes.

         g.  When finished, EXIT by hitting the "SETUP" box again.


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 for a model: choose 2500 Series; indicate the size of your board, number of buttons on
          your
          cursor,  the COM in which the board is plugged. It will  ask if you wish to choose Polling or Interrupt. If you have
          a 486/66 or Pentium system, choose Polling. With the 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 ACADR13\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
