Inputs/Outputs
Two
MSIB
Input/Output
connectors
and
one
HP-IB
connector
are
located
on
the
rear
panel.
Each
module
can
have
an
interface
to
the
MSIB
bus
and
to
the
HP-IB
bus
.
Hewlett-P
ackard
Interface
Bus
(HP-IB).
The
HP-IB
connector
provides
feedthrough
communication
among
controllers
,
other
HP-IB
instruments
,
and
with
each
module
installed
in
the
mainframe
.
Hewlett-P
ackard
Modular
System
Interface
Bus
(MSIB).
The
MSIB
is
the
high-speed
digital
bus
used
by
master
,
slave
modules
and
other
elements
for
exchanging
control
information
and
data.
It
consists
of
both
an
internal
and
an
external
bus
.
The
internal
bus
is
housed
in
the
HP
70001A
Mainframe
and
connects
to
each
installed
module
within
the
mainframe
.
External
MSIB
cables
connect
mainframes
to
each
other
,
to
the
Graphics
Display
,
and
to
other
MSIB
compatible
devices
.
This
external
MSIB
bus
allows
multiple
instruments
to
communicate
and
be
displayed
simultaneously
.
The
use
of
longer
MSIB
cables
allows
you
to
locate
a
display
some
distance
from
the
rest
of
the
instrument.

Mainframe/Module
Interconnect
The
mainframe
has
slots
to
accommodate
eight
1/8-width
modules
.
Each
of
these
slots
has
air
holes
to
deliver
cooling
air
and
a
multiple-pin
connector
providing
power-supply
voltages
and
MSIB
connections
for
module
communication
and
control.
