Potential for Radio and Television Interference
This
equipment generates
and
uses radio frequency energy
and,
if
not
installed
and
used in accordance
with
this
manual,
may
cause interference
to
radio
and
television reception.
It
has been
tested
and
found
to
comply
with
the
limits for a Class B computing device
pursuant
to
Subpart
J
of
Part
15
of
FCC
Rules, which
are
designed
to
provide reasonable protection against such
interference
in
a residential installation. However,
there
is no
guarantee
that
interferenc.e will
not
occur in a
particular
installation.
If
you
think
your
computer system is causing interference,
turn
off
the
system.
If
the
radio
or
television reception does
not
improve, your
computer
system is probably
not
causing
the
interference. In
the
unlikely event
that
your computer system does
cause interference
to
radio
and
television reception,
you
are encouraged
to
try
to
correct
the
interference by one
or
more
of
the
following measures.
• Relocate
the
radio
or
TV
antenna.
• Move
the
computer
system away from
the
radio
or
television.
•
Plug
the
computer
system
into
a different electrical
outlet,
so
that
the
system
and
the
radio
or
television are on
separate
electrical circuits.
• Make sure
that
all your peripheral devices comply with
FCC
Class B limits.
• Make sure you use only shielded cables
to
connect peripherals
to
your
computer system (except for HP-IL peripherals).
1-2 Installation
• Consult your computer dealer, Hewlett-Packard, or an experienced
radio/television technician for
other
suggestions.
•

Handling Circuit Boards and ICs Safely
Circuit
boards
and
ICs (integrated circuits)
are
subject
to
both
electrical
and
mechanical damage. Be sure
the
computer
is
turned
off while you
are
installing
or
removing
the
measurement coprocessor. Handle
the
measurement
coprocessor
and
memory
boards
gently
and
by their edges. Avoid touching any
components on
the
boards unless told
to
do so.
Electrostatic
discharge can damage
computer
circuitry.
It
is recommended
that
you wear a grounded
antistatic
wrist
strap
(available from
many
electronic
supply dealers) during
the
installation procedure. However,
if
you do
not
have
a wrist
strap,
you can discharge
static
electricity safely by touching
the
metal
surface
on
the
back panel
of
your computer.
Repeat
this step often during
the
installation procedure.
Unpacking and Inspection
If
you are installing
the
measurement coprocessor for
the
first
time,
unpack
it
as follows:
1. Remove
the
measurement coprocessor (in its protective
antistatic
bag) from
the
shipping box.
2. Following
the
precautions given in
the
previous section, remove
the
measurement coprocessor from
the
antistatic
bag
and
lay
it
on
top
of
the
bag, component side up.
Installation 1-3
The
following figure shows
the
measurement coprocessor
and
identifies some
components
of
interest:
RAM-1
RAM-2
FPU
In
the
figure above,
the
two memory-board locations
("RAM-l"
and
"RAM-2")
are outlined with dashed lines. Your measurement coprocessor should have
at
least one memory
board,
installed
at
the
factory in
the
RAM-llocation.
(The
measurement coprocessor will not function
if
there is no memory board in
the
RAM-llocation.)
There
may
also
be
a memory board in
the
RAM-2 location,
depending on
the
memory option you ordered. For further information
about
the
memory boards, refer
to
"Installing
the
Memory Boards"
later
in this
manual.
The
figure also identifies
the
hardware configuration switch, SW1, which is
shown in its default configuration (all segments in
the
"closed" position).
The
Floating-Point Unit
(FPU)
mayor
may not be present depending on
the
options you ordered.
If
the
FPU
is not present, there will be
an
empty socket
for
it
in
the
location shown
in
the
figure.
1-4 Installation
The Hardware Configuration Switch
The
hardware configuration switch (SW1) has six segments. In
the
factory
default configuration all six segments are set
to
the
"closed" position, as
shown
in
the
figure on
the
previous page.
(That
is, all six levers
are
in
the
"straight-up" position.) For
most
applications, you should leave all six segments
in the default position. However, in multiple-coprocessor installations, each
measurement coprocessor
must
have a
separate
address.
If
you need
to
change
the
address
of
the
measurement coprocessor,
or
if
you
want
it
to
be
"non-system controller" on
the
HP-IB, you will need
to
change
the
settings as
described below.
Note
If
the
measurement coprocessor is already installed
in
your
computer, you need
not
remove
it
to
change
the
switch settings.
(SWl
is accessible from
the
top.)
Just
turn
off your computer,
remove
the
cover,
and
change
the
settings as required.
Segments 1 and
2:
Primary Address
You can select one of four
primary
addresses by
setting
segments 1
and
2
of
SWl.
(The
default address is 250 hexadecimal.)

Segment 6
of
SWI
determines whether
the
measurement coprocessor is
the
system controller on
the
HP-IB. In
the
default ("closed") position, segment 6
specifies
that
the
measurement coprocessor is
the

Installing the Memory Boards
The
HP
82324 High-Performance Measurement Coprocessor has no memory
on
the
main board,
but
there are two memory locations,
RAM-l
and
RAM-2,
where memory boards can be installed. Two memory boards are available.
The
HP
82325 1 MB Memory Board provides 1 MB (megabyte)
of
RAM
(random
access memory), while
the
HP
823264
MB Memory Board provides 4 MB of
RAM. These boards look
the
same,
but
are identified by labels on
the
back. A
memory
board
(either 1
ME
or
'"
ME)
must
be
installed in the
RAM-l
location
in order for the measurement coprocessor to function. For additional memory,
a second memory
board
may be installed in
the
RAM-2Iocation. However, if
both
a 1 MB
and
a 4 MB memory
board
are installed, the'"
ME
board
must
be
installed
in
the
RAM-l
location.
The
HP
82324 High-Performance Measurement Coprocessor auto-configures
itselffor
the
amount
of memory installed, provided
the
physical memory
configuration is valid. The following table shows the valid configurations:

Removal Procedure
Normally you
won't
need
to
remove a memory
board
from
the
measurement
coprocessor once
it
is installed. However,
there
is
an
exception.
If
you
are
installing a 4 MB
board
on a measurement coprocessor
that
has a 1 MB
board
in
the
RAM-l
location, you will need
to
remove
the
1 MB
board
and
install
the
4 MB
board
in
the
RAM-l
location. You
may
then
install
the
1 MB
board
in
the
RAM-2 location.
Before you begin, read
the
installation procedure
in
the
previous section
and
become familiar
with
the
precautions.
Then,
follow these steps:
Caution
, Before you
attempt
to
remove a memory
board,
you
must
remove
the
screw
that
secures
it
to
the
measurement
coprocessor. Serious damage
may
result
if
you fail
to
do this.
1.
Turn
the
measurement coprocessor so
that
its
component side is down
and
remove the retainer screw that secures the
memory
board.
2.
Once
the
screw has been removed,
turn
the
measurement coprocessor so
that
its

and
lay
it
on
its
antistatic
bag (if available).
3. Loosen
the
connectors
that
hold
the
memory
board
in place by gently
prying, first
at
one
end
and
then
at
the
other,
using a plastic pen
or
the
eraser end
of
a pencil:

Installing the Floating-Point Unit
The
HP
82327 Floating-Point Unit
(FPU)
is
an
MC68882 floating-point
coprocessor IC, which provides increased
computation
speed.
The
FPU
may
have been installed
at
the
factory, depending on
the
options ordered.
If
the
FPU
is
not
present,
the
FPU
socket will be
empty
and
you can install
the
FPU
as described below.
Caution
, Follow
the
procedure carefully, particularly regarding
the
alignment
of
the
FPU
in
its
socket.
It
is possible
to
damage
the
FPU
and
the
socket
if
you are
not
careful. Also, follow
the
precautions in "Handling Circuit Boards
and
lCs
Safely."
1. Remove
the
FPU
from
its
protective anti-static package.
2. Look
at
the
figure
that
follows. Note
that
the
FPU
and
the
socket on
the
measurement coprocessor each have one notched corner. These corners
must
be aligned in
order
to
insert
the
FPU
in
the
socket. Also,
the
FPU
has a
"dot"
indicating
its
top
edge, which must align with
the
"arrow" in
the
socket, as shown.
1-12 Installation
3. Make sure
that
you have oriented
the
FPU
correctly over its socket. Lower
the
FPU
into
the
socket loosely
and
make sure that all
of
the leads are
aligned with the corresponding leads
in
the socket.
4.
Support
the
board
from behind with your fingers
and
insert
the
FPU
into
the
socket by pressing with your thumbs.
You can now go on
to
the
next section, "Installing
the
High-Performance

your
HP
Sales
and
Service Office for assistance.
Installation 1·13
Installing the High-Performance Measurement
Coprocessor
Before you install
the
HP
82324 High-Performance Measurement Coprocessor,
you should verify
its
configuration. (Refer
to
"The
Hardware Configuration
Switch.") You should also install any desired additional memory. (Refer
to
"Installing
the
Memory Boards.")
You can install
the
measurement coprocessor in any desired 16-bit slot.
The
measurement coprocessor takes
just
one full slot.
It
does
not
interfere
mechanically with cards in adjacent slots, even with two memory
boards
installed. However, DIO interface cards (SRM
or
GPIO)
must
be installed in
the
slots immediately
to
the
left of
the
measurement coprocessor (as seen from
the
front of
the
computer) so
that
the
DIO cables can be connected
to
the
measurement coprocessor. Leave space for any DIO cards you have.
Installation Procedure
After your measurement coprocessor is configured, install
it
in
your computer
as follows:
Caution
I Electrostatic discharge can damage computer circuitry. Follow
the
precautions given in "Handling Circuit Boards
and
ICs
Safely" throughout
the
installation.
1.
Turn off your computer and unplug
it.
2.
Remove
the
cover from your computer.
If
you have a desktop Vectra
PC,
remove
the
three
screws shown
in
the
figure
that
follows, slide
the
cover
forward
about
1 1h inches,
and
then lift
the

Installation
1-15
Caution
, Because
of
the
HP-IB connector on
its
back panel,
the
measurement coprocessor cannot be inserted
straight
into
the

guide. Also,
the
back panel is equipped with a
metal
"gasket"
to
ensure a good ground connection. This gasket is
easily bent. To avoid damaging
the
measurement coprocessor,
follow
the
installation procedure carefully.
4. Pick up
the
measurement coprocessor
at
the
front
and
back along
the
top
edge. Note that "back" refers to the end
of
the measurement coprocessor with
the
HP-IB
connector.
5. Holding
the
front
of
the
measurement coprocessor slightly higher
than
the
back, engage
the
back panel in the slot so
