respond
to
commands
sent
by
TaskLink.
This
is
the
primary

mode.
Security
Fuse
A
location
in
a
programmable
device
that,
when

secures
the
device
from
readback:
the
data
in
the
device
becomes
unreadable.
Security
Fuse
Data
The
data
programmed
or
that
will
be
programmed
into
the
device's
security
fuse.
Security
Option
A
programming
parameter
defined
in
the
Task
the
enables
or
disables
the
programming
of
the
device's
security
fuse.
Select
Device
A
procedure
that
tells
the
2500
programming
electronics
what
device
you
will
be
using.
You
select
a
device
by
choosing
the
manufacturer
and
device
part
number
off
a
list
on
TaskLink's
screen.
Self-test
A
command
that
tests
various
circuits
and
subsystems
in
the
2500
programming
electronics,
verifying
proper
operation
or
isolating
possible
problem
areas.

Serial
Vector
Test
A
device
test
that
applies
test
vector
input
states
serially,
starting
with
pin
one
and
stepping
through
the
remaining
pins.
This
test
is
a
diagnostic
tool
designed
to
help
debug
and
classify
test
vector
failures.
Specifically,
this
test
is
designed
to
isolate
test
vectors
that
are
sequence
dependent.
SMT
An
acronym
for
Surface
Mount
Technology,
an
approach
to
designing
and
manufacturing
electronic
circuit
boards
where
the
component
leads
are
mounted
on
the
surface
of
the
board
rather
than
inserted
through
holes
in
the
board.
SOIC
An
acronym
for
a
Small
Outline
Integrated
Circuit.
These
are
surface
mount
devices
(see
SMT)
with
two
parallel
rows
of
gull-wing
leads.
SPA
An
acronym
for
Squirt
Pin
Array.
These
are
the
spring-loaded
gold
pins
located
in
the
programming
station.
Programming
signals
from
the
2500
programming
electronics
pass
through
these
pins
to
the
programming
module
circuit
board,
and
through
the
programming
module
contacts
to
the
device.
STOP
Commands
A
set
of
commands
entered
from
the
front
panel
that
allow
the
operator
to
change
operating
parameters
without
having
to
exit
a
running
Task.
Stop

Structured
Test
Vectors
A
string
of
test
conditions
applied
to
a
PLD
in
a
programmer/tester
to
stimulate
inputs
and
test
outputs
to
ensure
functionality.
A
test
vector
is
one
such
string
—
for
example,
20
characters
for
a
20-pin
PLD,
with
10
input
signals
and
10
expected
outputs.
Sumcheck
A
four
to
eight
digit
hexadecimal
number
that,
when
compared
to
the
original
data,
allows
you
to
verify
that
a
copy
of
the
data
matches
the
original
data.
The
length
of
the
sumcheck
is
a
user
selectable
parameter
in
TaskLink.
Test
Vector
Test
vectors
functionally
test
the
device,
using
structured
test
vectors
stored
in
memory
or
in
a
disk
file.
Translation
Formats
A
form
of
transmission
protocol,
these
formats
are
used
when
transferring
data
between
the
2500
and
the
PC
or
a
host
computer.
The
different
formats
represent
different
ways
of
encoding
the
device
data
in
a
data
file.
The
data
file
could
contain
the
fuse
pattern
for
a
logic
device
or
the
data
for
a
memory
device.
Upload
Data
A
file
transfer
operation
that
involves
sending
data
from
the
2500
to
a
PC
or
host
computer.
Verify
Device
A
device
operation
that
compares
data
in
a
programmed
device
with
data
in
RAM
or
in
a
disk
file.
With
logic
devices,
verifying
can
also
include
functional
testing.
Verify
is
an
automatic
part
of
the
program
operation,
but
additional
verify
operations
can
provide
useful
information
about
any
errors.
Verify
Pass
A
verify
pass
is
a
pass
through
a
device
at
a
specified
Vcc
to
see
if
the
device
programmed
properly.
The
pass
is
usually
done
once
at
5V.
The
pass
can
also
be
done
twice,
with
the
first
pass
at
5.5V
and
the
second
pass
at
4.5V.
