Obtaining Mark and Space Outputs
The
schematic
diagram
of
the
KAM
indicates
that
Mark
and
Space
outputs
are
available
on
pins
11
and
18
of
J4
(DB-25
connector)
Provisions
have
been
made
for
obtaining
these
outputs
AFTER
installing
jumpers
between
the points
provided
on
the
PC board.
This
is
accomplished
by
locating
the
four
holes
in
the board marked
MA
and
SP
and
adding
wire
jumpers
between
them.
One
pair
of
holes
marked
MA
and
SP
are
located
next
to
the
DB-25
connector
(J4)
and
the
other
pair
is
located
on
the
opposite
end
of
the
board.
Install
jumpers
from
MA
to
MA
and
SP
to
SP
and
Mark/Space
signals
will
then
be
present
at
pins
11
and
18
of
J4.
It
is
advisable
to
install
a
100
Kohm
resistor
in
series
with
these
lines
to
protect
the
KAM
from
external
voltages.
