SPECIFICATION
Introduction
The Tektronix
015-0175-00
Joystick
is
an
input
device
intended for use with the Tektronix
4901
Interactive
Graphic Unit.
The
Joystick provides X and Y Axis
posi-
tioning voltages from high resolution sensing elements using
a single control handle. An opening
in
the
enclosing shroud
limits travel of
the
control handle.
The
Joystick can be
calibrated
so
the perimeter
of
the
opening
in
the
shroud
corresponds
to
the
limits
of
the
display area
on
the
T4002
Terminal Display
Unit,
or some portion
of
the
display area.

OPERATING
INSTRUCTIONS
OPERATING INSTRUCTIONS
General
To
effectively
use the
015-0175-00
Joystick, the
opera-
tion and
capabilities
of
the instrument must be known. This
section describes the operation of the instrument controls
and indicators and gives the adjustment procedure
neces·
sary
to
modify instrument
calibration
to
meet specific
needs.
Instrument Controls
CURSOR BRIGHTNESS and
IG
OFF.
This
is
a
dual
purpose
control
that
varies the intensity of
the
crosshair
cursor
display
and,
in
the switch detent position
of
the
control, disables the
Interactive
Graphic
Unit
to
which the
Joystick
is
connected.
Control Handle. This single
handle located
in
the square
cutout
area of the
enclosing
shroud
is
mechanically connec·
ted to the potentiometers
that
supply the X and Y Axis
positioning voltages. With the Joystick situated so the
READY
light
and
CURSOR BRIGHTNESS/IG OFF con-
trol
face the user, pushing the
control handle away
will
position the crosshair cursor
display
toward the upper part
of the
display area. Setting
the
control handle
to
the user's
left will position
the
crosshair cursor display
to
the
left
part
of the
display area.
The
perimeter of
the
cutout
area
in
the
enclosing
shroud corresponds
to
the
limits
of the
display
area of the
T4002
Graphic Computer Terminal Display
Unit.
READY Light. The READY light
indicates, when it
is
lit,
that the
Interactive
Graphic
Unit
to
which
the
Joystick
is
connected
is
ready
to
accept new X and Y Axis positional
information.
The
READY
light
can
only
be
lit
when
the
CURSOR BRIGHTNESS/IG OFF control
is
in
some
posi·
tion other than
IG
OFF.
Connectors
P
1000
is
a 37
-pin
connector used
to
connect the
Joy-
stick
to
the
Interactive
Graphic
Unit
being used.
Construc-
tion of the plug eliminates the possibility of improperly
installing it. A
locking
device on
PlOOO
securely attaches it
to the mating connector
on
the
Interactive Graphic
Unit,
and eliminates accidental disconnection or
removal.
Calibration
Adjustments are
accessible
on
the bottom panel
of the
Joystick
to
facilitate calibration.
The Joystick,
as
it comes
2
from the factory,
is
calibrated
so the opening
in
the en-
closing shroud corresponds to the
limits of the display area
of the
Terminal Display Unit.
However, the instrument can
be
recalibrated
to
make the opening
in
the shroud
corres·
pond to some
lesser
portion of the
display
area with no
detrimental
effect
on
operation. Refer
to
the
following pro·
cedure for instrument recalibration.
1.
Install
the
4901 Interactive
Graphic
Unit
in
the
Aux·
iliary
Compartment of
the
T4002 Graphic Computer
Ter·
minal and connect the
015-0175-00 Joystick to the
4901.
2.
Obtain
a crosshair cursor
display
on
the Terminal
Display Unit.
3.
Set the
control
hand
le
of the Joystick
to
position the
intersection
of
the crosshair cursor display
to
the
upper-
most part
of
the
display
area.
4.
ADJUST-Y
Gain adjustment R12
to
set the inter·
section of the crosshair cursor
display
to
the
vertical posi·
tion desired.
5. Set
the
control handle
of the Joystick
to
position the
intersection of the crosshair cursor display
to
the
lowest
part of the display area.
6.
ADJUST-Y
Offset adjustment R 18
to
set the
inter·
section of the crosshair cursor
display
to
the
vertical posi-
tion desired. There
will
be interaction between step 4 and
step 6. Readjust
until
there
is
no further interaction.
7.
Set
the
control handle
of the Joystick
to
position the
intersection
of
the crosshair cursor display
to
the extreme
right-hand part of the display
area.
8.
ADJUST

to
set the
inter·
section
of
the
crosshair cursor
display
to
the
horizontal
position desired.
9.
Set

to
position the
intersection of the crosshair cursor
display
to
the extreme
left·hand
part
of
the
display
area.
10. ADJUST
-X
Offset
adjustment R 15
to
