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
Guide
The
end
of
the
input
track
that
each
device
rests
against
before
the
beam
picks
it
up.
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.

Wildcard
A
global
search
character
used
to
speed
the
search
for
a
specific
device
name
or
file
name
in
TaskLink.
When
entering
filenames,
a
wildcard
represents
one
or
more
characters
in
a
filename.
For
example,
27*.dat
represents
both
27512.dat
and
27128.dat.
Yield
The
percentage
of
successfully
programmed
devices.

Firmware
Keys
and
STOP
Commands
The
ProMaster
2500
is
normally
operated
in
remote
mode
using
the
TaskLink
software.
Some
of
the
firmware
key
commands
listed
in
this
Appendix
are
active
only
while
the
handler
is
in
local
mode.
To
execute
a
firmware
key
command
from
one
of
the
handler
menus,
perform
the
following
steps:
1.
Put
the
handler
into
local
mode
by
pressing
the
LOWER
CASE
+
L
keys.
2.
Go
to
the
appropriate
menu
and
press
the
key
sequence
to
access
the
display.
3.
Enter
the
new
numeric
value
or
answer
the
prompt
from
the
2500's
keyboard
and
press
START.
The
2500
supports
a
second
set
of
commands
known
as
STOP
commands,
because
the
commands
are
entered
after
pressing
STOP
to
pause
the
2500.
These
differ
from
the
firmware
key
commands
because
they
can
be
used
while
processing
devices
so
you
do
not
have
to
exit
the
current
Task.
