Examples
The
following
examples
are
intended
to
demonstrate
decoding
of
various
learn
string
bytes
that
are
coded
in
different
formats
.
The
bytes
are
sent
from
the
logic
analyzer
over
the
HP-IL
cable
or
the
HP-113
bus
.
These
examples
assume
HP-113

Format
ASCII
format
is
used
at
various
points
in
many
of
the
logic

learn
strings
.
One
usage
of
the
ASCII
format
is
in
the
StateLabel
Overview
Learn
String
.
The
last
five
bytes
in
each
23
byte
interval
range
represent
the
state
label
name
formatted
in
ASCII
.
When
the
following
commands
are
sent
from
a
Series
200
controller
to
the
logic
analyzer,
the
State

will
be
received
by
the
controller
.

The
most
common
usage
of
the
binary
coded
decimal
and
integer
formats
is
the
encoding
of
the
Date/Time
settings
.
The
precise
byte
positions
of
these
parameters
within
the
particular learn string
is
in
the
learn
string
listing
.
The
interpretation
of this
information
is
given
in
thefollowing
example
.
The
byte
positions
are
from
a
State
Trace
Learn
String
which
are
bytes
5
through
11
in
the
learn
string
.
The
Date/Time
is
August
28,
1985
at
10
:50:07
.
Interpreting
the
hexadecimal
representations
for
month,
day,
hour,
and
second
are
straightforward
.
The
month
is
represented
from
O
to
11
as
described
for
month
in
Date/Time
Information
previously
in
this
chapter
.
However,
the
integer
decoding
for
the
year
is
not
as
apparent
.
It
can
be
regarded
as
having
the
MSB
(most
significant
byte)
coming
first
as
