Baud Selection.
Both
of
the
MicroLab
|
RS-232-C ports have
a
selectable
baud
rate.
J1080
(the
square
pinson
the
left
in
this
illustration)
selects the
baud
rate
for
the terminal
connector.
J1070
(on
the
right)
selects the
baud
rate
for
the
modem connector. The
square
pins labeled
J1060
allow
the modem connector to act
as
either
a DTR
or a
CTS
device.
Connecting a
Cassette
Recorder
The
lid
of
the
MicroLab
|
contains two cables
that
terminate
in
audio plugs. Connect one cable to the
OUT
jack on the
MicroLab
I,
and the
other
cable to the
IN
jack.
Connect the
free
end
of
the
OUT
cable
to
the
recorder's
earphone
jack,
and the
IN
cable
to
the
recorder's
AUX
jack.
REV APR

If
there
is
no
AUX
jack
on the recorder,
you
should connect
a
100-ohm,
1/4-Watt
resistor
either
across
C7089
inside
the
MicroLab
|,
or
across
the
plug (signal
to
ground)
that con-
nects
MicroLab
|
to the recorder; then
connect
the
IN
cable
to the recorder’s microphone
input jack. Addition of
this
shunt
resistance
is
necessary
to prevent
overdriving
the
cassette
recorder’s microphone
input.
