Q Pointing tools

- 4 -

Drawing area

The drawing area is the rectangular surface area on the
tablet located below the menu strip (see figure). This is
where all your work is performed. The small format
tablets (12" x 12", 12" x 18", and 18" x 24") have a clear
plastic cover over the drawing area that can be used to
secure artwork or templates.

Menu strip

The menu strip is the row of keys located at the top of the
tablet on small format tablets and in the lower left corner of
the tablet on large format tablets. You can use these keys to
customize your tablet or to assign macros for greater
productivity.

Indicator light

There are two indicator lights within the menu strip: power and configuration. The power light turns on when the
power is on. It also indicates whether the pointing tool is within range of the drawing area. The power light glows
if the pointing tool is inside the drawing area and blinks if it is outside the drawing area.

The configuration light turns on whenever you select the Config/Exit key. You will also hear a beep. This means
the tablet is in configuration mode and you can make changes to the Configuration keys. The light stays on until
you select the Config/Exit key again, exiting configuration mode. A double beep sounds.

Pointing tools

There are two types of pointing tools available with
DrawingBoard III: pens and cursors.

The pointing tools are available in both corded and
cordless versions. The cordless pointing tools are powered
by batteries.

Each tool goes into a battery-saving “sleep mode” when
no button has been pressed for one to five minutes,
depending on the type of tool you are using. To reactivate
the tool, press any of its buttons.

Cursors

The cursor is similar in appearance to a mouse, except that it has an attached lens with crosshairs for highly
accurate detail work. Cursors are available with 4 or 16 buttons. There is a special 16-button cursor available
with high accuracy tablets. This corded cursor has a lens area that can be illuminated.

Pens

The pen is similar in appearance to a ball-point pen. It has a button built into the tip plus two side buttons on the
barrel. There are three types of pens that are identified by a colored ring on the pen barrel:

Q Click tip: Light blue ring
Q Pressure tip: Black ring
Q Lite touch tip: Red ring

Installing the software

The TabletWorks software included with your DrawingBoard III tablet allows you to use your tablet both as a
mouse and a digitizer, and to access all tablet features and capabilities through the TabletWorks control panel.
Refer to TabletWorks Help for instructions on installing the software and for customizing your tablet.

Special cases

Some unique situations may not require the use of the Digitizer Software. These cases are rare, usually in a
non-Windows CAD application where the tablet is used solely as a digitizer with no mouse functions. In these
situations, you can set up DrawingBoard III manually via the menu strip. Refer to the Customizing the Tablet
section for step-by-step instructions.

All mouse applications, including all Windows applications and AutoCAD, must have the Digitizer Software
installed to work properly with the tablet.

Learning the Basics

You will find that using your DrawingBoard III tablet is as easy, or easier, than using a mouse. The
DrawingBoard III pointing tools are more accurate than a mouse giving you greater control over your move­ments.

Topics discussed in this section:

Using the pointing tools

Learning basic movements

Using the pointing tools

The pointing tool does not need to be in contact with the tablet surface in order for the tablet to sense its pres­ence. It can be detected up to 1/2" above the drawing area. This allows you to trace through materials placed on
the surface, such as a drawing or a book. Also, before using the pointing tool, be sure that sleep mode is turned
off by pressing any button on the tool.

Using the cursor

When you use the cursor, the intersection point of the
crosshairs on the lens identifies the point you are selecting.
The crosshairs are etched on the bottom of the lens to in­crease accuracy. For maximum precision, look through the
lens from directly over it.

Button 0 on the cursor is used as the pick (or left mouse)
button. All other buttons are defined by the TabletWorks
software or through your own software application.

High accuracy cursor

To illuminate the lens area of the high accuracy cursor, press and hold any button in the far right column (3, 7, B
or F); at the same time, press and hold any button in the far left column (0, 4, 8 or C). The right column button
must be held down while pressing the left column button. This same procedure turns the illumination off. The
illumination defaults to off when the tablet is first powered on.

Because you will always need one right column button and one left column button free to control the cursor
illumination, you should reserve one button in each column from any macro recording.

Warning: The DrawingBoard III high accuracy cursor resembles the cursor for the 9500 series tablet. Although
the only difference seems to be the presence of the row of LEDs above the top row of buttons on the 9500 series
cursors, do not interchange these cursors as damage to both tablet and cursor may result.

- 8 -

Using the pen

There are three variations of pens: the click tip, the pressure tip
and the lite-touch tip. All the variations are tilt and height
sensitive. The pen tip is Button 0 and is used as the pick (or left
mouse) button. The lower side button is Button 1 and the upper
side button is Button 2.

The functions these buttons provide are defined through the
TabletWorks software or through your own software application.

Click tip pen

The click tip pen is available in both corded and cordless versions.It is primarily used for tracing and menu
picking. To use the pen, press down until you feel the tip click.

Pressure pen

The pressure pen is only available in the cordless version. With the pressure pen, the pen tip can be used both
as a mouse button and a pressure-sensitive button. To take advantage of the pressure feature, the software
package you use must recognize pressure sensitivity. The software assigns values to the pressure levels and
uses this data to vary such parameters as line width and color.

To use the pen, press down on the tip and release for a mouse pick action. Press down and hold for the pres­sure action. Pressure increases as you continue pressing down on the tip. To decrease the pressure, ease up on
the tip.

Learning basic movements

The DrawingBoard III pointing tools provide all the basic movements of a mouse. The basic movements are
clicking, double-clicking and dragging.

Clicking and double-clicking

Clicking is the action of making a selection. You may be selecting a key on the tablet surface or making a
selection from the monitor screen. To click, place the pointing tool (or move the screen pointer via the pointing
tool) to the item to be selected then tap the pen or press Button 0 on the cursor. A double-click requires you to
tap the pen or press the button quickly two times while the tool remains in the same place. You can also double
click by pressing the pen or cursor button that has been defined as a double-click button (see TabletWorks
Help).

Dragging

Dragging is the action of moving the pointing tool during a selection. To drag, click on an object but instead of
releasing the tip or button, hold it down while moving the pointing tool (or corresponding object on the screen) to
the desired new location.

- 9 -

Customizing the Tablet

You can customize your DrawingBoard III tablet and pointing tool to suit your individual work requirements
using TabletWorks. TabletWorks is a Windows program included with the Digitizer Software that helps you use
the full capabilities of your tablet. You can map your tablet to the screen area, record your own macros and
designate areas on the tablet to switch between open software applications. To learn how to use TabletWorks,
please refer to TabletWorks Help.

You can also customize your tablet using the menu strip. However, if you use the Digitizer Software, the software
will override the menu strip setup.

Topics discussed in this section:

Overview of the menu strip

Selecting a pre-programmed setup

Selecting a custom setup

Recommended setups for common PC software packages

Restoring a pre-programmed setup

Overview of the menu strip

The menu strip is composed of:

Q Config/Exit key

The Config/Exit key turns configuration mode on and off.

Q 3 Bank keys

There are three Bank keys: A, B and C. Each bank has a different set of tablet options that are available
through Configuration key combinations.

Q 18 Configuration keys

The keys numbered 1-18 can be used as both Configuration and Macro keys. When the tablet is in configu­ration mode, they function as Configuration keys. These keys allow you to set specific tablet options by
turning different combinations of Configuration keys on or off.

When configuration mode is off, the keys function as Macro keys. Macros can only be recorded with
TabletWorks software (see TabletWorks manual).

Q 3 Save and 3 Restore keys

The Save and Restore keys work hand-in-hand. They are used to save (or recall) a setup to (or from) one of
three save areas. There are three pre-programmed setups that come with the tablet. You can use these
setups directly or overwrite them with your own. The Default Save key controls the first save area. The setup
saved to this area is activated whenever you power up the tablet. We recommend you save the setup you
use most often as Default.

Selecting a pre-programmed setup

There are three pre-programmed setups available with DrawingBoard III:

Q GTCO DP5 High Resolution Binary
Q Summagraphics MM 1201
Q CalComp 2000 ASCII

These setups are used commonly within software applications as required tablet formats. They are stored in
Save areas Default, 2, and 3, respectively. Check the manual that came with your software package to see if
your application requires one of these pre-programmed setups. The Default setup is available when you power
on the tablet.

Topics discussed in this section:

Cleaning the tablet

Replacing the pen tip

Replacing the pen batteries

Replacing the cursor batteries

Cleaning the tablet

To clean the tablet’s surface, use a soft, non-abrasive cloth. Hardened dirt may be removed with a slightly
dampened cloth. Do not clean pencil lines with a soft cleanser or pencil eraser. This may create an undesirable
shiny spot on the tablet’s surface that cannot be removed.

Warning: Do not use abrasive cleaners, acrylic or lacquer paint thinners, or cleansers with an acetone or solvent
base, such as MDC or EDC, on the tablet surface. They will damage the tablet case.

Replacing the pen tip

To replace the pen tip, grasp the tip and pull
straight out (see figure). Insert the new tip and
press until it clicks into place.

- 19 -

Replacing the pen batteries

The pens require two 393 silver oxide batteries. The average battery life is 750 to 1,000 hours.

Warning: Do not use ZINC AIR batteries as replacement batteries. They will corrode the electronics of the pen.

To replace the batteries:

1 Unscrew the pen cap. Hold the pen from the

bottom and gently slide off the pen cover to
expose the batteries.

2 Remove the old batteries by turning the pen

over and gently tapping it, letting the
batteries fall into your other hand.

3 Insert the new batteries as they are shown

in figure above (“+” towards pen tip).

4 Replace the pen cover then screw the pen

cap onto the pen.

Note: When you replace the pen batteries, the pen will reset to the default frequency. If you changed the fre­quency of the pen before replacing the batteries, you will need to do so again after replacing the batteries (see
the Reducing Monitor Interference section in Solving Problems).

Replacing the cursor batteries

The cursor requires two AAA batteries. The average battery life for the cursor batteries is 4,000 hours.

To replace the batteries:

1 Place the cursor face down in the palm of your

hand. Use a Phillips screwdriver to remove the
two screws located on the bottom of the cursor
(see figure). Remove the cursor base.

2 Remove the old batteries from the battery

casings.

3 Place the new batteries in the casings, matching

the polarity of each battery with the markings on
the connector strips (match + to +).

4 Reposition the cursor base. Replace the screws

with the Phillips screwdriver.

Note: When you replace the cursor batteries, the cursor will reset to the default frequency. If you changed the
frequency of the cursor before replacing the batteries, you will need to do so again after replacing the batteries
(see the Reducing Monitor Interference section in Solving Problems).

Is the tablet power switch on?

Does the power light glow steadily when the pointing tool is inside the drawing area? Does it blink when the
pointing tool is outside the drawing area?

The power light will blink if the pointing tool has gone into sleep mode. Press any button on the tool to
activate it. If the power light continues to blink and the pointing tool is in the drawing area, change the
pointing tool’s battery.

Are all cable connections tight?

Power cable to serial connector?

Pointer cable to tablet?

Serial cable to tablet?

Serial cable to computer? Check that the cable is connected to the serial port specified in your software
package.

Is the tablet set up according to the software recommendations?

Are any of the connector cables or receptacles damaged? Check for bent pins, cut insulation, and loose
wires.

Computer checklist

Is the computer plugged into a live outlet? Did you turn on the computer?

Does the computer work with any software? Try one of your other programs. If the computer has a diagnos­tic diskette, use it.

Is your software package installed correctly?

Does the serial port work? The only way to test the port without special equipment is to reinstall something
that has worked in the past and test if it still works.

Have there been any recent electrical storms in your area that may have damaged your equipment?

Software checklist

Does the tablet work with some software?

If your tablet currently works with some software packages, you know that the tablet, serial port, and computer
work.

Even if the software package you are trying to install and the software that is working both support the same
tablets, it does not always mean that you can use the same tablet settings. The output format may be the
same, but the communications protocol, resolution, operating mode, and data rate may be different. Check
your software’s requirements.

Call the software manufacturer. Perhaps the software package has a problem with another component of
your system.

Did the software work in the past?

If the software package worked with the tablet in the past, then the problem lies with the new setup.

Check all the connectors. Is the tablet still plugged into the same port? If yes, reset the tablet by unplugging
and replugging the power supply and restart the software.

Did you reset or power down the computer?

During reset and power on the computer can send meaningless characters out the serial port and this can
disable the tablet. Reset the tablet again.

Have you installed any new software or hardware? Remove it from your system and see if the problem goes
away.

Did you move any cables?

If you are using a PC, did the new software alter your AUTOEXEC.BAT file?

Have you updated the software or its drivers?

Are you loading another mouse driver?

Did you reinstall the software, perhaps after a problem with your hard drive? Double check your installation
procedure and the driver you selected.

Reinstall the software from its master diskettes. The program files may have been corrupted.

Glossary

Accuracy

The similarity of a distance measured by the tablet with the actual distance. When we specify that the accuracy
of a tablet is ± .010 inches, we mean that every point in the drawing area is within .010 inches of where it should
be.

ASCII

Abbreviation for American Standard Code for Information Interchange.

Baud rate

The rate of speed that data flows between a host computer and the digitizer. It is the number of bits transmitted
per second. The lower the baud rate, the slower the speed.

Bit

The basic unit of information in the binary system—either 0 or 1.

Button

A switch on the cursor or pen used to input data.

Byte

A group of eight bits that acts as a single unit of information.

Coordinate pair

A pair of numbers representing a unique point on the digitizer surface, usually the distance across and up from
the tablet origin.

CR

The ASCII carriage return character usually added to the end of the X,Y coordinate pairs sent by the tablet
(ASCII formats).

Cursor

1) A pointing tool used to select specific points on the tablet surface. 2) A symbol displayed on the screen

marking where the next action will take effect or where the next character typed from the keyboard will appear.

Data bits

Each transmission contains 7 or 8 data bits.

Data rate

The number of coordinate pairs (X,Y) the tablet sends to the computer per second.

Default

A value, action or setting that a computer system assumes unless the user gives an explicit instruction to the
contrary.

Drawing area

The area on the tablet surface intended for digitizing.

Format

The form in which data is sent from the tablet. The DrawingBoard III tablet can output 32 different formats.

Frequency

The number of waves that pass a fixed point in one second.

Height

See Proximity.

- 27 -

Increment modes

This mode is used with other operating modes. Data points are sent only if the pointing tool has moved the
required increment distance in either the X or Y direction and has satisfied the requirements of the operating
mode. These increment distances are set separately for each axis.

Jitter

A repeatability error of short duration caused by electrical noise.

Key

A portion of the tablet surface available to the user for tablet setup.

Line feed

Optional character added to the end of an output format that causes the printer to move to the next line, or
causes a line to be added on the display screen.

Line mode

The tablet sends coordinate data points continuously, while the pen tip or a cursor button is depressed, and one
additional point when the pen tip or cursor button is released.

LPI

Abbreviation for line per inch. English unit of measurement for resolution measuring the number of separate,
distinguishable locations that may be found within the distance of one inch.

LPmm

Abbreviation for lines per millimeter. Metric unit of measurement for resolution measuring the number of sepa­rate, distinguishable locations that may be found within the distance of one millimeter.

Mouse mode

An operating mode that emulates Microsoft and Mouse Systems mouse drivers. Data constantly transmits when
the cursor or pen is on the drawing area of the tablet.

Operating mode

The conditions that must be met before the tablet sends information to the computer.

Output format

The system of characters used by the DrawingBoard IV tablet for outputting data.

Parity

A type of error detection where a bit is inserted into every character the digitizer transmits. The status of the
parity bit confirms that the data was not altered during transmission.

Pen tilt correction

An option that allows for tilt correction in the pressure pen.

Pen tilt data

An option that allows output of tilt data in the pressure pen.

Point mode

The digitizer transmits one coordinate data point when a cursor button or the pen tip is depressed.

Pointing tool

The tool used to digitize; it may be either a cursor or pen.

Pressure pen data

Data output from the pressure pen.

Prompt mode

The digitizer transmits one coordinate pair each time the computer sends a prompt character to the unit.
Prompting can operate with any mode except Mouse mode.

- 28 -

Proximity

The greatest distance above the drawing area that the pointing tool can be raised and still be sensed by the
tablet.

RAM

Abbreviation for Random Access Memory, a specific type of memory used by the computer.

Resolution

The distance increment that the tablet outputs in lines/inch or lines/mm.

ROM

Abbreviation for Read Only Memory, a specific type of memory used by the computer.

Run mode

The digitizer transmits coordinate data points continuously, regardless of the status of the cursor buttons or the
pen tip. This mode is also called Stream by some manufacturers.

Serial transmission

Data transmission protocol where each bit of the data character is sent one at a time over a single circuit. This
system saves on transmission circuitry, but is usually slower than parallel transmission.

Stop bits

One or two stop bits are transmitted with each data byte. They mark a completed transmission.

Track mode

The digitizer transmits coordinate data points continuously, but only while the cursor button or pen tip is de­pressed. This mode is also called Switch Stream by some manufacturers.

X direction

The horizontal direction across the face of the tablet.

Y direction

The vertical distance up and down the face of the tablet.
