cription___
The
HP
PC
Instruments
Digital
I/O
is
an
instrument
that
can
send
and
receive
16-bit
data
words
through
the
input
and
output
connectors
on
the
front
of
the
unit.
It
does
this
under
the
control
of
a
computer
that
is
equipped
with
PC
Instruments
software
and
an
interface
card.
The
System
Owner's
Manual
tells
you
all
you
need
to
know
about
the
required
software
and
interface
card
for
your
computer.
Chapters
2
and
3
of
this
manual
explain
how
to
operate
the
Digital
I/O
"
manually"
using
the
Soft
Front
Panel
(computer
display)
while
Chapter
5
describes
programming
statements
you
can
use
to
control
it
from
BASIC.
Figure
1-1
is
a
block
diagram
that
illustrates
the
two
primary
functions
to
the
Digital
I/O.
These
functions
are:
Digital
Input
and
Digital
Output.
The
16
data
bits
of
both
the
Digital
Input
and
Digital
Output
can
be
addressed
individually
or
simultaneously
as
a
word.
In
this
way
you
can
specify
variable
length
data
words
up
to
16
bits
long
as
well
as
their
location
on
the
input
and
output
connectors.
The
input
data
bits
are
compatible
with
all
logic
levels.
Programmable
circuitry
on
the
instrument
allows
you
to
specify
an
input
threshold
level.
The
output
data
bits
can
be
programmed
to
be
compatible
with
either
TTL
or
open
collector
logic
levels.
In
addition
to
the
16
data
bits,
the
input
connector
and
the
output
connector
also
contain
two
control
signals
and
four
digital
commons
each.

Digital
I/O
Block
Diagram
Two
basic
operating
modes
are
available
for
I/O
data
transfers:
synchronous
and
asynchronous.
Synchronous
operation
requires
that
some
other
instrument
or
hardware
source
must
communicate
with
the
Digital
I/O.
This
two-
way
communication
is
referred
to
as
'
'handshaking'
When
sending
data
to
an
external
device,
the
Digital
I/O
signals
the
external
device
that
data
is
available.
The
external
device
completes
the
handshake
by
returning
a
signal
that
indicates
it
has
received
the
information.
When
receiving
data
from
an
external
device,
handshaking
requires
that
the
external
device
must
first
signal
the
Digital
I/O
that
data
is
valid.
To
complete
the
handshake,
the
Digital
I/O
will
return
a
signal
to
indicate
it
has
successfully
received
the
data.
terns
Supplied
In
asynchronous
mode,
the
computer
alone
controls
the
transmission
of
data
on
the
Digital
I/O's
input
and
output
bits.
Any
data
that
is
sent
by
the
computer
immediately
appears
on
the
output
bits.
Data
that
appears
on
the
input
bits
is
immediately
read
into
the
computer.
Data
transmission
is
not
dependent
on
any
control
signals.

manual,

Introduction
The
following
step-by-step
procedure
allows
you
to
perform
some
simple
instrument
operations.
This
procedure
is
especially
suitable
for
first
time
users
who
want
to
quickly
become
familiar
with
the
basic
operation
of
the
Digital
I/O.
Chapter

contains
additional
operating
information
that
you
can
use
once
you
have
learned
the
basics
in
this
chapter.
The
Procedure
Trying
out
your
instrument
consists
of
pointing
to
and
selecting
various
interactive
fields
on
the
Soft
Front
Panel.
Before
you
try
out
your
Digital
I/O,
you
should
have:
connected
it
to
the
interface,
applied
power,
loaded
the
operating
system,
renamed
(or
erased)

to
return
the
instrument
to
its
factory
default
settings,
and
run

as
explained
in
Chapters

of
your

and
one
for
the
Digital

DIG.OUT.Ol
is
the
factory

The
letter
D
after
the

indicates
that
the

each
additional
Digital

will
be
