WITH
A BBC
MASTER
NOTE
When
using a 501
TOUCHTECH Monitor
with
a
BBC
Master
it is
necessary to
set the correct
Data and Baud
rates. This is
achieved
by
adopting
the following
procedure:
1 Switch on
the Monitor
and BBC Master.
2 Type in
the following:
*
C0. DATA

return
*C0. BAUD

NOTE
This procedure
need only
be performed
once, as the
information
is
retained in memory
even after the BBC
Master has
been switched
off.

INTRODUCTION
Welcome
to the new and
important
concept
involving
the
interaction
of
man
with machine
The TOUCHTECH
501.
Your TOUCHTECH
501 provides you with
a
powerful alternative to
the
standard keyboard
for communicating
with the
computer.
The TOUCHTECH
501
is
based
on the
latest
infra-red
scanning
technology
which enables it to detect
a finger or object
placed
within the plane
of
the monitor
screen
and communicate
the
co-
ordinates of this
position
to the computer
with great accuracy.
It
is
this
facility that
permits a unique and direct interaction between
the
computer
user and the computer program, without the need
for
the user
to
turn away from the screen
in order
to select one
key or
another during
the
course of
the
program.
Many
applications
are possible
using the
TOUCHTECH
501. These
will range from
use with
young children, where Touch
Screen
operation
will be particularly
useful in providing a
completely
natural way to interact
with educational programs
on a
microcomputer,
through
to business-style application
programs like
database
or spreadsheets, or
for other applications
that benefit
from
a menu
driven approach.
The
programs
supplied
with
your
TOUCHTECH 501 are general
examples chosen
to illustrate some of the
possibilities.
The
programs
demonstrate several
styles of use. However the 8 modes
of operation within TOUCHTECH
501 permit many other
possibilities.
For those
users with ‘BASIC’ programming skills, adapting
existing
programs
for use with
the
TOUCHTECH 501 is relatively straight-
forward. This involves
the
addition of two small
‘BASIC’
routines
to the existing
program. Full details
of these routines are provided
within
the handbook. A
Utilities program ‘BOXMAKE’ is provided
to facilitate this.
We
wish you success
with
your
TOUCHTECH 501
and
we are sure
you
will find that
it offers a
new and exciting
dimension
to the
computer and for
software
development.

GETTING
STARTED
ASSEMBLY
INSTRUCTIONS
All
cables
have
been omitted
for clarity.
After unpacking
your
TOUCHTECH
501, you
must attach the feet
(1)
to the
base
of
your
Touch Screen.
Firstly
the feet
(1),
as shown.
Then
using
screws (2)
secure the feet
(1) to
the base
of the
Touch
Screen.
FIG.
1
Having
assembled
your TOUCHTECH
you
must now
fit it to your
‘M’
series monitor.
Position
equipment
as shown, then
raise the
monitor
so that feet
(3 are located
inside
feet (1).
Slide the
monitor forward,
then slightly
raise the
rear of the
monitor
so that feet (2)
are located
inside feet (1).
FIG. 2

Your monitor is
now pre—set
at the correct viewing angle,
you
must
now make
the
electrical
connections
in
order
to get your
TOUCHTECH
fully operational.
FIG.

ELECTRICAL
CONNECTIONS
We
will
now look
at
the
electrical
connections
required in order to
get
your
TOUCHTECH
501
fully
operational.
1. There
are two
leads
to be connected, the first is the power lead
(1). This
plug
fits into
the disc drive
power
port (2) on the
underside
of your
micro,
and
provides
:5
volts d.c.
2 The plug
(3)
connects to your
disc
drive
power
plug
(4).
3. The
only
other
connection
is
to your socket
marked ‘Disc
Drive’ (5).
1. The
second lead connects to a 5 pin
din plug (1) which is
fitted
to the RS423
port (2) at the rear of your micro.
Note:
The
plug
must
be
fitted with the gap (3)
in
the
plug
uppermost.
2 The lead (4)
to your
monitor
connects in the normal way.
RGB
(micro
to
TTL (monitor).
Now
all that’s left to
do
is
to switch
‘ON’
your
monitor and micro
and enjoy
your
TOUCHTECH 501.

RE-SET
SWITCH
We will
now look at the re—set switch
(1) its
position
and its
function.
POSITION
1. The re—set switch
(1)
is located
underneath
the front
panel of the
TOUCHTECH
in the centre.
FUNCTION
1.
The
function
of
the re—set switch is to
re-set the
on—board
processor!
Should
the system ‘crash out’
the
re-set
switch
should
be
pressed
to initialise the processor.

CHECK
LIST
If your new TOUCHTECH
501
does not
operate the
following
steps
will
establish
whether the TOUCHTECH is
faulty. It is
important
that you carry out these checks before
returning
the equipment for
Warranty repair.
1. Ensure that the
supply
voltage
is
‘ON’
(the
LED
on the
front
of
the
TOUCHTECH
should be illuminated).
2 Ensure
all
electrical
connections are correctly fitted (refer to
‘ELECTRICAL
CONNECTIONS
section
of
this
handbook).
Some of the possible fault
causes
are:-
A.
Check
input lead
is correctly
fitted,
ensure plug is not upside
down in
the
RS423
socket.
B. Ensure that
the
diskette is
correctly
loaded
(see
instructions
on
diskette).
3 Press the re—set switch.
4 If
possible try the TOUCHTECH with another micro, disk drive
or
monitor (‘M’
series
only)
to
establish
location
of
fault.

DEMONSTRATION
PROGRAMS

MENU
SCREEN
To
choose
a
program
touch
the
relevant blue box.
The
box
chosen
will turn
black
and the
program
will be
loaded from disk on
removal
of your
finger.
TOUCH
OUTLINE
This
program
demonstrates
the
essential
operation of the
Touch
Screen its ability
to identify the
position
of the finger,
represented by a cross on
the
screen.
The program may also be
used to
adjust
alignment.
USING
THE
PROGRAM
1.
Finger position
Place
a finger onto the screen. A cross
should appear on
the
screen
underneath or
near
to the
tip of the finger.
Move
the
finger slowly around the screen and
the
cross should
follow it. The x and y
values
that appear
on the screen
represent
the finger position
which
are
on
a
scale
of 0-120 on
x axis and
0-90
on the y
axis.
2. Alignment
Ideally, the
finger should be as
near to the perpendicular
as
possible so
as
to
avoid effects of parallax.
This
can
occur
because
the
detection plane of the Touch
Screen
lies
slightly
in front of the
glass of the screen. In
most
circumstances
this
effect will
not
be
noticeable.
6

If it
is necessary
to adjust the alignment of
the Touch
Screen
then
this option
may be
selected by touching the
box marked
‘Align’
You
will
be
asked
to
place
a perpendicular
finger onto a point
where a constant
sound is
heard.
At this
point the cross may be re-
aligned by using the arrow keys.
Press the ‘return’
kev
to
finish.
3.
Object
size
To see a demonstration of the ability of the
Touch Screen to
detect
the size, as well as the position
of objects,
touch
the
box
marked
‘Plot
Area’
Move
a
finger
around
the screen
and a series of rectangles corresponding
to the area
of the
object will be
drawn
on the
screen.
Place
a
larger
object, or
the edge of
the hand against the screen
and
larger rectangles
will be
displayed.
This represents the use of Touch Screen ‘size
mode
2
(see
‘Software
Notes for further
details).
The
display
may be cleared by touching the ‘clear’
box. Touching
the ‘continue’
box
will
end
this section
of the program.
Touch ‘Menu to
return

MUSIC
OUTLIN_E:-
This
program is a three-stage
menu-driven music synthesiser. The
program presents an on-screen keyboard that can actually
be
played by lightly touching each
key.
The three stages allow the
instrument
to be played directly, a particular sound to be
created
graphically
and
a section
of
musical
score created
using a pre-
stored or newly
created sound.
Stage one represents the keyboard and a range
of options
that
allow a number of instruments to be mimicked,
and
different
ranges
of
octave
to be
selected.
This
stage
is
also used to select the tempo at which a section
of
music will be played back in the third stage of the
program.
Stage two will
permit
the creation
of a new
sound
that can
be
stored under
the
boxes ‘sound
1
‘sound
2’ and ‘sound 3 This is
accomplished by directly
manipulating graphically each of eight
parameters that describe
a
given
sound.
The
third
stage is a musical
editor that allows a single
voice
to be
created on a musical score as the keys are touched.
This can be
edited and played back.
All
the
main options in this
program
need
to be touched
twice to be selected.
USING
THE
PROGRAM
Stage 1 Keyboard
First
choose
a given
instrument
by touching
the appropriate
box.
Note
that the initial three
special sounds are undefined
at the
beginning
of the
program.
Choose
a particular
duration
of note, quaver
or semi-breve, and
a
given
octave
and the
keyboard is ready
to play.
