INTRODUCTION
606-2.
The
Bit Serial
Asynchronous
Interface
provides
remote
programming
capability in
applications
where
speed
is
riot
a critical factor.
Switch
selectable
baud
rates,
stop
bits,
and current requirements
permit
maximum
flexibility.

The
Bit Serial
Asynchronous
Interface
meets or
exceeds the requirements for
data transmission
and
reception of
EIA
Standard
RS-232B

NOTE
Make
sure
the leaf
spring
,
attached to
one-
half of the
module
shield,
is
resting
firmly over
the
flange of the
opposite half
of
the
module
shield
.
4. If
installed,
remove the Interconnect
PCS
from
slot
K. This
slot
can
be identified as the
only
slot
with connectors
on
the
analog and
digital
bus
lines.
To
remove
the Interconnect
PCB,
grasp the
board
at
both
ends,
and
pull up.

5.
The
Isolator
module must
be
installed in slot
K
whenever
a
remote
interface
(Option
-05,
-06 or
-07)
is
used in the
DMM.
NOTE
Use
Isolator -08
with
the
8500 A;
Isolator
-08
must be used with
the
8502
A.

The
Bit Serial Interface
is
easily installed as
a
module
in
the
8500
series
DMM.
Use
the following
installation
procedure:
1.
On
the
DMM,
press
power
OFF
and remove
the
line
power
cord.
2.
Remove
the
DMM's
top cover.
3.
The
Interface
module
fits
in
the rear
slot,
bus
connector and
address switches facing to
the
rear.
Slide the
module
vertically
between the
module
guides,
and
press firmly into place.

EIA
Standard
RS-232-C
provides the electronics
industry with the
ground
rules
necessary
for
independent
manufacturers
to
design
and produce both
data terminal
and data
communication equipment
that
conforms
to
a
common
interface
requirement.
As
a
result,
a
data
communications
system can be formed by connecting an
RS-232-C
data terminal (such
as
the
8502A)
to
an
RS-
232-C data
communications
peripheral (such as
a
TT
Y,
MODEM,
computer,
etc.).
This
works
fine
on
paper.
However,
in
practice the user
must
be
aware
of the
subtleties
of
serial
binary data interchange
to
ensure that
any two pieces of
RS-232-C equipment
will
be
compatible.
For example, the
two
instruments
