INTRODUCTION
Welcome
to
a new
dimension
of
computer
graphics! Your Series ONE Graphics Tablet offers a
wide variety
of
graphic
features
that
will allowyou to draw, menu select and add the dimension
of
graphics
to
your
computer
system.
Yourgraphicstablet is compatible with manygraphicssoftware packagesavailable
for
personal
computers
supporting
an RS232 serial interface. It may also be used in
conjunction
with BASIC,
assembler,
or
other
language
programs
that you may write
for
your
own applications. In fact, we
have
included
some
BASIC
programs
that
will
show
you
how
the
tablet works, and also may help
get you started writing
your
own
applications programs.
The
Series
ONE
Graphics
Tablet is
microprocessor
driven and uses a pen
or
optional
cursor
to
generate
output
data
consisting
of
x and y
coordinates
as
well
as
pen status information. A
soft
keyboard provides tablet
control
with thetouch
of
the pen
or
optional cursor. Themicroprocessor
will also accept
commands
loaded
from
the host computer. Programmable point, draw, delta,
auto, and menu modes as well
as
origin
relocation and resolution scaling
support
many tablet,
workstation and keyboard applications.
YourTablet can
output
datascaled
to
match
the
host
monitor
pixel requirements. The hostcan
also program a change
to
other
resolutions
for
printer
output
or
data calculations. The built-in,
powerful
microprocessor
minimizes host processing, control, and management tasks.
The
following
pages detail
configuration
information, setup instructions, and examples
of
BASIC
programs
that
demonstrate
how
your
Tablet works. Take a few minutes
to
familiarize
yourself with them
as
you become acquainted with the unit.

PEN AND CURSOR ASSEMBLIES
PEN ASSEMBLY
PEN PRESSURE
AND
SWITCH OPERATION: Your
PEN has an internal switch housed inside the
BARREL ASSEMBLY. The switch
is
activated when
the PEN is pressed
down
on
any
surface; however,
MENU
FUNCTIONS
or
X,
Y coordinates are
transmitted
only
when.the pen
is
in
proximity
to the
MENU
or
WRITING SURFACE.
NOTE:
Normal
writing
pressure
is
sufficient to fully
activate the PEN SWITCH. (Press the exposed tip
of
the CARTRIDGE
to
your
finger
to see and feel the
amount
of
movement and pressure required.)
Although the pen
is
ruggedly designed
for
years
of
use, it
is
still a preCision instrument. Do
not
jam the
switch
or
otherwise abuse it.
TO
DISASSEMBLE: Turn PEN TIP counter-
clockwise. Remove CARTRIDGE
or
PEN
from
BARREL ASSEMBLY being careful
not
to
lose
SPRING.
TO
REASSEMBLE: Insert
new
or
replacement CARTRIDGE
into
BARREL
ASSEMBLY. Replace SPRING
on
CARTRIDGE.
Replace PEN TIP and turn clockwise to tighten.
NOTE: The CARTRIDGE supplied with pen
has,!2Q

CARE
AND
HANDLING:
Although
your
3-Button
Cursor
is
designed
of
durable plastic,
you
should
exercise care while handling and cleaning it.
Do
not
drop
the Cursor
or
get it wet. Cleaning
requires only a soft cloth
lightly
dampened with
anon-abrasive
cleaner
which
does
not
harm
plastics.
NOTE: DO
NOT
clean the
Cursor
with chemicals
~sive
materials which may harm
or
scratch
the
plastic-especially
the clear lens area.
CURSOR OPERATION: Your optional Cursor has
preCision crosshairs which allow greater accuracy in
locating points to be digitized. The Cursor provides
operation equivalent to the
Pen
when using Switch
S1,
and much greater capability when using the
flexibility
of
all three switches in
conjunction
with
Software programs.
SWITCHES: Each
of
the three switches
is
coded
separately, so the switches may be used individually
or
in tandem giving
eight
(8)
possible combinations.
Switch
S1
is
identical in operation
to
PEN SWITCH.

Type RUN and depress the RETURN key. Touch the pen down
in
the lower left corner
of
the active
area.
The X and Y values should be approximately zero. Since the tablet is set to POINT mode, each time you
touch the pen down in the active area a single data output for X and Y will occur.
Now move the pen
to
the right and confirm that the value
of
X increases each time you press the
pen
down.
Do the same for
Y.
The values
of
X and Y should change
200
counts for each inch
of
movement
in
the X
or
Y direction.
NOTE: Pressing the pen down activates the
pen
switch which transmits the signal to the
computer.
Press
the pen firmly but
do
not strike the
pen
tip on the surface
as
that
action may damage both the pen and the surface.
Place the pen on the menu keyboard over the LO
RES
menu location. Press the pen down on the circular
black area underthe word LO
RES.
Now touch the pen down on the active area several times
as
you move
from left
to
right. Confirm that the resolution is 100 points per inch.
Try to activate the
pen
on a surface away from the tablet, no X
or
Y data should appear.
Touch the pen
to
ORIGIN SET and then to a location in the center
of
the tablet. The data should be zero
upon pen down and should increase in value
to
the right and up from this new origin location. This capability
can be used to set the start point
for
data
or
the location
of
a paper
or
form. Touch CLEAR
to
reset the menu
to its initial lower left corner position.

OPERATION (continued)
NOTE: When using DELTA,
DRAW,
or
AUTO mode with this TEST program, the volume
--
of
tablet output data may cause a BUFFER OVERFLOW condition indicating the
computer string buffer is full. If this occurs, restart the BASIC program and reduce
the time you transmit data.
Touch the pen to DELTA mode. Now place the pen on the active area. The X and Y position data change
only
when the pen switch is activated and the pen moves
0.01
inch. If the pen switch
is
activated and the pen
is
not moved, data output will stop.
Touch the pen to DRAW mode. Now place the pen on the active area. The X and Y position data should
only change when drawing on the surface. Note how the data stops when the pen pressure
is
removed.
Touch the pen
to
AUTO mode and raise the pen about two inches above the active area. Lower the pen
slowly and note that data will start appearing on the screen when the pen
is
approximately % inch above the
surface. No pen switch activation is required.
Spend some time learning the basic functions
of
the tablet and confirming proper operation.
You
are then
ready to advance to more significant use
of
the tablet in operation with application software.
See
Appendix
1:
Origin Set and Resolution.
MAINTENANCE AND SERVICE

allows
reconfiguration
of
the cable interface to
accomodate
different hardware
or
software
requirements. The reconfiguration is made possible
through
the use
of
quick
disconnect
pins within the

If a male

is
required, obtain a shielded adapter from
your
local
computer
store.
2)
The
connector
normally
is shipped as
configured
above with Pin 4 disconnected because the tablet does
not
require Clear
to
Send
to
operate. (If Pin 4 is connected, you must have a logic one
input
or
tablet will be
inhibited.)
3)
If
your
computer
or
software program requires the
input
and
output
channels to
be
reversed (consult
your
computer
or
software manual), reconfigure the
connector
as
required using the
