Chapter 3 Digitizing with Summagrid IV

This chapter provides an overview of Summagrid IV, including how the tablet works and
information on using the stylus and cursors.

3.1 Operational Overview

3.1.1 Overview

Summagrid IV is a digitizer. A digitizer is an input device that translates graphic
information, such as a drawing or photograph, into a computer readable format.

The Summagrid IV has two main parts: tablet and pointing device. The pointing
device may either be the stylus or cursor. The stylus/cursor emits a low-intensity
signal. A grid within the tablet reads this signal with the stylus/cursor is moved
across the tablet.

Therefore, for the tablet grid to sense this signal, the stylus/cursor must be used
over the grid, or active area and close enough to the grid, or in proximity. (Active
area and proximity are described below.) The Summagrid IV expresses the
stylus/cursor position as an X, Y coordinate pair, which is called a report. Valid

reports can only be collected when the stylus/cursor is in the tablet’s active area and
in proximity. Reports are in absolute coordinates (measured from the tablet’s

origin) and are expressed in inches, millimeters or counts of resolution (described
below).

3.1.1.1 Active Area

The active area is the region on the tablet surface in which the stylus/cursor
position can be identified. It’s marked on the tablet by corner brackets.

3.1.1.2 Proximity

Proximity is the maximum distance above the active area that the stylus/cursor
can be held and report a position. The proximity limit for the Summagrid IV is
.50”. Together, the active area and proximity establish a three-dimensional
volume within which the stylus/cursor can issue reports. Reports issued from
outside this volume are out of proximity (out-of-prox) and, therefore, do not
represent the current position of the stylus/cursor.

3.1.1.3 Resolution

Resolution is the “fineness” of detail that the tablet can distinguish. Resolution is

expressed in lines per inch (lpi) or lines per millimeter (lpmm).

Reports are measured in counts of resolution. One count is the distance
between two lines of resolution. As shown below, each square is one count of

Summagrid IV 14

Summagrid IV 15

resolution. The tablet reports the same coordinates for any point within the
square.

With different resolution settings, the user can receive different reports for the
same tablet location. In the illustration below, points A and B are the same
physical locations on the tablet, but their coordinates are different because of
the resolution setting.

The Summagrid IV tablet provides two different resolution functions: Fixed and
Variable resolutions.

3.2 Using the Stylus and Cursors

3.2.1 Overview

Summagrid IV supports several different stylus and cursor options, which are
described below. Any of these transducers may be used corded or cordless,
depending on the users’ preference.

3.2.2 Summagrid IV Stylus and Cursor Options

A stylus is a pen-shaped instrument used to locate points on the tablet. With its
similarity in size and shape to a pen or pencil, it is natural to the hand and is
recommended for freehand drawing. Summagrid IV supports a three-button stylus.

A cursor is a handheld device, also used to locate points on the tablet. The cursor
has a cross hair for precisely sighting points and is therefore recommended for
tracing and menu picking. Summagrid IV supports two different cursor options:

 Four-Button Cursor
 16-Button Cursor

3.2.3 General Tips

 The cursor is the most accurate when held parallel with the tablet surface.

To activate, press a cursor button.

 The three-button stylus has two barrel buttons and a refill tip button. Locate

points on the tablet by gently pressing any of these buttons.

Summagrid IV 16

 The cursor and stylus buttons are programmed by the application software.

Reference the application’s manual for information on programmable

options.

 When using the stylus/cursor cordless, if you notice a decrease in the

proximity limit or no proximity at all, you may need to replace the
stylus/cursor batteries. Refer to Chapter 2 for information on how to install
the batteries. If you do not have extra batteries on hand, you may use the
stylus/cursor corded until you obtain batteries.

4.1 Introduction

4.1.1 Overview

This chapter is a guide to using the Summagraphics Drivers/Utilities software. It
assumes the user has experience with basic DOS tasks such as changing directories,
copying files and creating batch files. If the user is unfamiliar with any of these
tasks, refer to a DOS user’s manual before continuing.

4.1.2 The Drivers/Utilities Diskette

You’ll find four subdirectories on the drivers/utilities diskette:

 ADIDVR – Contains the UIOF format drivers for Autodesk® applications (both

protected mode and real mode versions).

 TABLTDVR – Encompasses the UIOF format version of the Summagraphics

tablet driver/Microsoft® mouse emulator.

 WINDVR – Contains the UIOF format Wintab-compliant drivers for Microsoft®

Windows

 UTILITY – Accommodates the following utilities: UIOFRST, SG3TEST and SEND

Summagrid IV 19

Before installing any of the drivers or utilities, make a backup copy of the
Drivers/Utilities diskette. Use only your copy and store the master in a safe
place.

4.1.3 DOS Prompt vs. Batch Files

Run most of the Drivers/Utilities by typing commands at the DOA prompt, or by
creating batch files. We have included examples of running the drivers/utilities from
the DOS prompt, as well as sample batch files, throughout the chapter. Additional
information on batch files and how to create them can be found in the DOS user’s
manual.

4.1.4 TSR Applications

Some of the drivers in this manual are TSR (Terminate and Stay Resident) programs.
Strange behavior in the software can be caused by the sequence in which the user
loads or runs TSR programs on the system. If this occurs, experiment with the
loading sequence. If one sequence does not work, try another.

4.2 Summagraphics Driver for Autodesk Applications

4.5.1 Introduction

There are two UIOF/Microgrid format drivers for Autodesk applications. Use these
drivers if AutoCAD has already been configured for a real or protected mode ADI
driver.

NOTE: Summagraphics’ ADI drivers are less likely to encounter initialization
problems when “shelling out” of AutoCAD, therefore, Summagraphics recommends
using the ADI drivers supplied on the Drivers/Utilities disk instead of AutoCAD’s

internal drivers.

Summagraphics provides both a real mode driver and a protected mode driver:

 DGMG.COM – Real mode driver for ADI™ (Autodesk Device Interface)

applications. This driver can be used on all DOS versions of AutoCAD.

 DGPMG.EXP – Protected mode driver for ADI version 4.2 supported

applications. Use this driver if you have a release 11 or 12 386 DOS extender
version of AutoCAD and wish to take advantage of AutoCAD’s protected
mode capabilities.

Summagrid IV 20

DGMG.COM and DGPMG.COM require tablet dip switches to be configured as follows:

Check Summagrid DIP switches to confirm the proper settings.

4.2.2 Using DGMG.COM

First make sure that DGMG.COM is in the current directory. Then, at the DOS
prompt type the following:

DGMG [Com port] [Transducer] [Mode] where [com port], [transducer] and [mode]
are replaced with the options listed below. If the user only types DGMG, the tablet
defaults to the options marked with an asterisk (*).

Summagrid IV 21

NOTE: Use of the /AS option makes DGMG.COM a non-ADI specification driver.
Although the /AS option allows the screen and tablet to have the same aspect ratio,
approximately two inches on the right-hand side of the screen cannot be accessed
when in this mode. As a result, certain dialog box buttons (Cancel and OK) cannot
be accessed by the tablet. However, the user may activate these commands by
using the ESC and ENTER keys on the keyboard.

The Summagraphics tablet driver/mouse emulator, TABLETMG.COM allows a
Summagrid tablet to emulate a Microsoft mouse. Use when the application’s setup
menu includes a listing for TABLETMG.COM or Microsoft Mouse (MOUSE.COM) and
the tablet dip switches are configured as follows:

Check the Summagrid IV DIP switches to confirm proper settings.

4.3.2 Using TABLETMG.COM

Make sure that TABLETMG.COM is in the current directory. Then at the DOS prompt
type the following:

TABLETMG [com port] [stylus/cursor] [tracking] [other options] where [com
port], [stylus/cursor], [tracking] and [other options] are replaced with the options
listed below. If you type only TABLETMG, the tablet defaults to those options
marked with an asterisk (*).

Summagrid IV 26

/C3

/C16
/CM####

Three-button stylus
Four-button cursor
16-button cursor
Allows a user-defined mapping of the cursor/stylus buttons. The
\CM argument is followed by 1-4 digits that specify which
stylus/cursor switches are assigned to standard mouse buttons.
Each digit represents that value of a stylus/cursor switch and its
position after the \CM argument represents the mouse button that it
is assigned to. The first digit after the \CM argument corresponds to
the left mouse button, the second digit to the right mouse button,
the third digit to the middle mouse button and the fourth digit
corresponds to an emulation of both the left and right mouse
buttons being pressed simultaneously.

NOTES:

 When using the BA (Base Address) option, all four digits must be specified.

Example: Com 1 - \BA03F8

 Use the \BA switch only when the serial port is located at a non-standard

address within the computer.

This option is the ballistic gain profile. It controls acceleration of the
screen cursor. The driver comes with four built-in ballistic gain profiles:
Slow, Moderate, Fast and Unaccelerated. Specify 1, 2, 3 or 4.

EXAMPLE:

TABLETMG \CM2134

The above example shows stylus/cursor switch #2 being mapped to the left mouse
button, stylus/cursor switch #1 being mapped to the right mouse button,
stylus/cursor switch #3 being mapped to the middle mouse button and
stylus/cursor switch #4 being mapped to both the right and left mouse buttons.

Tracking Options

The following options will work only if the application is set up to use a Microsoft
Mouse (MOUSE.COM).

Applications that are compatible specifically with TABLETMG.COM should configure
tracking automatically or allow the user to configure tracking through the

application’s set up utility. The use of the following options will be overridden by the

application.

Relative Mode /R

Relative mode is the default setting. There are four relative mode options:

Absolute Mode /A

Absolute mode maps the tablet’s entire active area to the computer screen. Relative

mode options (/S, /H, /V and /M) should not be used in Absolute mode.

NOTE: Applications accept input from MOUSE.COM as either absolute screen
coordinates or relative mouse units, also referred to as “mickeys.” Absolute mode
works only with those applications that accept input as absolute screen coordinates.
To verify that absolute mode is working, position the screen pointer, then lift the
cursor/stylus out of the tablet’s active area and place it at a different location on the
tablet. The screen cursor should snap to a new location. If it does not, then the

application works only in relative mode and the absolute mode option will have no
effect.

Other Options

Disabling the Driver

/OFF Disables Driver

Memory Location Options: /U, /E and /HI

These options allow the user to maximize the amount of memory available for DOS
application programs. The strategy is to move a majority of the TABLETMG.COM
drivers to a memory location outside of the 640K area used by most application
programs. The /U command moves the driver to the upper memory area between
640K and 1MB. The /E command moves the driver into expanded memory. The /H1
command shifts the driver into the high memory area between 1MB and 1.064MB.

The computer system needs to support these options before they can be used. The
designated memory must be installed as RAM. To use /E, the user must have either
expanded memory hardware, such as an Intel Above Board, or a software driver,
such as EMM386 or QEMM in the machine. To use /H1, the user needs to have an
80286, 80386 or 80486 family processor and the HIMEM.SYS driver (or equivalent)
loaded before installing the mouse driver. MS-DOS 5.0 systems should also have
the line.

DOS = UMB in the CONFIG.SYS file.

Only TABLETMG.COM can be relocated. TABLETMG.SYS cannot be relocated. The
user cannot relocate TABLET.COM into another memory area without first removing
the mouse driver by using the TABLETMG/OFF command.

4.3.4 Running the Driver from CONFIG.SYS

Another way to install the driver is by including TABLETMG.SYS as a device driver in
the CONFIG.SYS file. In doing so, the system automatically installs the driver each
time the user boots or turns on the system.

Line Syntax

DEVICE = TABLETMG.SYS [com port] [stylus/cursor] [tracking] [other options]

The command options are the same as for those running TABLETMG.COM from the
DOS prompt or a batch file. Most of the command line arguments described for
TABLETMG.COM also works for TABLETMG.SYS. The exceptions are the /OFF
command and the memory location options /U, /E and /HI.

Example: For a Summagrid IV with a 16-button cursor attached to Com 1:

DEVICE = TABLETMG.SYS /1 /C16

4.3.5 Changing An Installed Driver’s Parameters

Command-line options can be combined together. For example, the user can utilize
both /H and /V together, and it will work in the same way as using /S. Command­line options can also be issued after the driver is initially installed by running
TABLETMG.COM again. Another example, the user can go back and change the

sensitivity of the cursor tracking with the /S command option at any time. It is
possible to change the parameters of an installed TABLETMG.SYS driver using
TABLETMG.COM. The TABLETMG drivers will not install twice, as long as they are
the same version.

4.4 Summagraphics Driver for Microsoft Windows

4.5.1 Introduction

The Windows driver allows you to use the Summagrid IV tablet as a pointing device
with the Microsoft Windows software. The Windows driver requires the tablet dip
switches to be configured as follows:

Check Summagrid IV DIP switches to confirm proper settings.

The Windows driver also requires 250 kilobytes of free hard disk space. Before
installing the driver, check for free disk space by issuing the DIR command on the
target drive. DOS will respond with nnnn bytes free. If there is insufficient disk
space, remove or move enough files to accommodate the driver and run the
installed program.

4.4.2 Installing the Windows Driver

Below are instructions for installing the Microsoft Windows driver.

Windows must be installed on your system before installing the Summagraphics
Windows driver. If Windows is not installed on the system, follow the installation
procedures in your Windows manual.

1. Insert the Summagraphics Drivers/Utilities diskette into the A: Drive. At the DOS

prompt, type the following: A:[ENTER]

2. Change to the WINDVR directory by typing: CN \WINDVR [ENTER]

3. Run the INSTALL program by typing: INSTALL [ENTER]

The INSTALL program installs the Summagraphics Windows driver and the
SUMMA.EXE control panel program onto the computer. The INSTALL program
prompts for the following information.

 Hard drive where Windows is installed
 Name of Windows directory
 Whether you want to save (by renaming) the previous version of the

drivers or remove them

 Serial communications port to which your graphics tablet is connected

INSTALL then creates a subdirectory called SUMMA under the Windows directory, copies
the drivers and starts the Windows SETUP program.

4. In the Windows SETUP program, at the System Information screen, use the

up/down arrow keys to highlight the MOUSE line and press ENTER.

5. Use the up/down arrow keys to choose OTHER (requires disk provided by

hardware manufacturer) and press ENTER.

6. Type the full pathname of the SUMMA subdirectory under the Windows

directory. Example: C:/WINDOWS\SUMMA [ENTER]

7. Use the up/down arrow keys to select Summagraphics UIOF Wintab Driver and

press ENTER.

8. Accept the new configuration shown on the screen by pressing ENTER.

NOTE: If you’re reinstalling the driver, an anomaly with the Windows 3.1 Setup

program may occur. After selecting the required driver, the Setup program will

prompt again for the location of the driver. To continue, simply re-enter the

driver pathname.

9. Install the Summagraphics Control Panel icon in one of the program manager

groups so that it is easily accessible:

 Run Windows.
 Open the Windows Program Manager by double-clicking on its icon.
 Under the file dropdown menu, choose NEW.
 The New Program Object dialog box appears. Select Program Item and

click OK.

 The Program Item Properties dialog box appears. Type SUMMA in the

Description box. Enter the path name for the Summagraphics Control

Panel in the Command Line box and click OK. For example, if Windows is
installed on your C: Drive, in a directory called, WINDOWS, you would
type: C:\WINDOWS\SUMMA.EXE.

The SUMMA icon should appear in the current group’s window. If
desired, it may be dragged to a different group’s window.
