Instruction
Once you've
programmed the user programmable
key
vector,
it
need not be
programmed
again,
except
in
the
following
circumstances:
@
if
you
want
to
change
the
key
vector;
@
if
you
press the
RESET
key;
or
@
if
the
MicroLab| main
power
is
shut
off.
Using
PROM
to
Store
The
Key
Vector Table
Recall
that the personality
card
contains
a
spare
PROM
socket. At
reset,
the
MicroLab
|
monitor
checks
the
socket
for
the presence
of
a
PROM.
If
a
PROM is
present,
the
monitor loads
the
first 16
PROM
locations into
the
personality card’s
key
vector
table
automatically. This
means
you
can program aPROM
with
the
key
vectors
you'll
most often
want.
The
use
of
a
PROM
inthis
situation
does
not
prevent
you
from programming
the
key
vector
table
directly,
as
outlined before. Those capabilities
still
exist.
The
PROM
just
speeds
the
process.
If
you
try to
use
the
programmable
keys
without
setting
up
the
key
vector
table
(either with
a
PROM
or
directly),
the
MicroLab
|
will
ask
you to
do so
by
displaying
"dEFInE”,
and
then
“rEAdY”.
Using
the
MicroLab
|
With
A
Terminal
The
input/output
capabilities
of
the
MicroLab! can
be
increased
by
using an optional terminal. The
MicroLab
|
has
an RS-232-C
terminal
port
located on the right side
of
it's
chassis.
(It’s
the
upper
connector
in
Fig.
2-3.)
This port
can communicate
with your terminal at any
standard
baud
from
110
to 9600.

RS-232-C
Ports.
Although
these
ports
are
not
supported
by
the
MicroLab! monitor,
software can
be
written
to
access them.
