What is the
SummaSketch'?
How Does it Work'?
The SurnmaSketd1
1, a graphics tahlct.
A graphics tahlet
1s an input dev1n: that
lets you translate two-dimensional
information. such as a drawing. into a
computer readahle format. Its many
uses include:
tracing pictures. drawings. and
photos
freehand drawing
steering the pointer on a
computer
screen
picking locations on a menu
or
template
The
SummaSketch is a sophisticated
device.
It uses the latest advances in
electronics and electromagnetic
technology, which make it accurate and
reliable.
The SummaSketch has two main parts,
the tablet and the pointing device. The
pointing device can be either the stylus
or cursor. The cursor/stylus emits a
low-intensity signal. A grid within the
tablet picks up the signal to
'read' the
cursor/stylus location. Therefore, for
the
SummaSketch to do its job, the
cursor/stylus must be
over the grid and
close enough to
it to sense the signal.
Two terms describe this. They are
·active area· and
·proximity', which are
defined on the next page.

How l>ot'S it Work'?
(cont.)
active area --· -- ---- -
proximity= 1/2"
The area of the tablet where the
grid
is located is called the tablet
active area. Unless you have X-ray
vision, you can't see the active
area. So we etched a groove in the
tablet
surrounding it.
c===i !
The SummaSketch II active area is
I 1.7" x 11.7" (shown above). The
SummaSketch II Professional
active area is 18" x J2".
Proximity is the maximum distance
above the active area that the
cursor/stylus can be held and still
be
read by the tablet.
The proximity of the cursor/stylus
is 1/2-inch_ The cursor/stylus does
function at greater heights. but per-
formance, such as accuracy. begins
to suffer.
The advantage of pro ximity is that
the
cursor/stylus and tablet ne ed
not be in direct contact with each
other to work. You L·an draw and
trace through layers of materials ,
e.g.
drawings and rhotos . ur to the
proximity limit - - 1/ .:! -inch.

Preparation
Is Your
Computer
Set Up Correctly?
UIOF and MM
Configurations
For the tahlet to funl'lion with your
computer. the nnnputer hardware must
he set up correctly. and the
computer
software must support the
SummaSketch.
The comput er must have an RS-2.12-C
port.
This is an asychronous. serial,
communications port. The port mu.st be
configured as DTE (Data Tenninal
Equipment). which specifies that the
port transmit
data on Pin 2 and r ece ive
data on Pin 3. The port can have eith er
a 25-pin male D connector or a 9-pin
male D connector.
Additional
configuration information
appears in the appendices. If you are
unsure
whether your computer is set up
correctly, refer to the computer owner's
guide or call yo ur dealer.
The tablet operates in either the UIOF
(Universal Input Output Format) or MM
configuration. Each configuration has
its
own unique set of operating charac-
teristics
and report formats. When you
turn
on or reset the tablet. it defaults to
one of these configurations . It defaults
to the
MM configuration when the
stylus
or four-button cursor is attached.
It defaults to the UIOF configuration
when th e sixteen-button cursor is
attached.
Software is available to override the
defaults
and let you mix and match
configurations and pointing devices .
Refer to the
SummaSketch Drivers /
U1i/1ties
User 's Guide for details.

A Word About
Software
Installing the
SummaSketch
5
For the tablet to act as an input device,
your application must include a driver for the
tablet model you are using. The driver
allows your tablet and the application to
communicate with each other. It converts the
tablet output into information that the application
can understand and use. Most programs have
Summagraphics drivers built right in. (To
be
sure, refer to the software manual or contact the
software manufacturer.) Below
is a listing of
drivers required by the SummaSketch II Plus
tablets. If you are using a
SummaSketch II Plus (or SummaSketch
II Professional Plus) with a four-button
cursor or stylus, you must select the
SummaSketch (or
MM series) driver
within the application.
SummaSketch II Plus (or SummaSketch II
Professional Plus) with a 16-button cursor,
you must select the Microgrid (or UIOF)
driver within the application.
Below are the steps to installing your
SummaSketch.
1. Plug the cursor or stylus into the
top right socket.
The cursor and stylus are interchange-
able. However, when changing from
one to the other, tum
off the tablet.
(This allows the tablet's internal
firmware to fine tune for each device.)

Next. plug the 25-pin connector of
the interface cable into the host
communications port. If your
computer has a 9-pin port. use the
9-pin-to-25 -pin adapter between
the tablet cable and the computer.
3. Connect the power supply by
plugging its barrel connector into
the
interface cable's D connector.
Now. plug the power supply into a
st
andard clcl'lrical outlet. Use only
a SummaSkctch power supply. A
suhstitutc could damage the tablet
and would void the FCC certifica-
tion and
warranty.

4. Power up the tablet by pressing the
on/off switch. (Pressing it again
turns the tablet off).
on/off switch
power/prox light
The tablet is now up and running!
The power/prox light serves two
purposes. First, it lets you
know that
the tablet is on and receiving power.
Second, it is a proximity indicator. The
light remains lit when the cursor/stylus
is in-prox (in proximity). It blinks
when the cursor/stylus is out-of-prox
(out
of proximity). If the light blinks
when the cursor/stylus
is in-prox, two
possible problems exist. Either the
cursor or stylus is not connected to the
tablet,
or the tablet is malfunctioning.
Turn off the tablet, then turn it on. If it
fails again, contact your local dealer for
service.

Using the
SummaSketch
8
Using the SummaSketch is easy.
However, you·
II get the most from your
tablet if you follow these guidelines:
The cursor/slylus must be
in 1he
tablet active area and in proximity
(within I/2-inch
of th e tablet .
surface) for the tablet to work as a
pointing devic
e. Note: The tablet
power light is also a proximity
indicator. When the cursor/stylus
is in proximity, the tablet power
light is on. When the cursor/stylus
is out of proximity, the power light
blinks.
You can tape things down to the
tablet, like pictures and drawings.
Tape doesn't bother the tablet.
You can even stack materials up to
1/2-inch high between the tablet
and the cursor/stylus.
The
cur s or and stylus have the
same functionality. You can use
them to draw, trace, etc. Which
one should you use? The stylus is
mote natural to the hand, so it is
better for freehand drawing. The
cursor has the cross-hair for
precisely sighting points, so
it is
better for tracing and menu picking.
The cursor and stylus are inter-
changeable. However, when
changing from one to the other,
tum off the tablet. (This allows the
tablet's internal firmware to fine
tune for
each device.)
The cursor is most accurate when
held parallel with the tablet surface.
To activate a cursor button, press it.
When tracing, use the cross hair to
precisely sight information.

The stylus has two buttons. the
barrel button and the refill tip.
To
activate. press gently.
The unit is affected by conductive
materials. Don't trace through
metal
or metallized paper. Don't
use metal objects. such as rulers on
the tablet. With the cursor.
however, you can trace through
some conductive materials, such as
X-rays
or drawings in pencil or
conductive ink.
When you turn off the computer,
also turn
off the tablet.
