2.4.6
Programming
Commands
Programming
of
the
ZPV
corresponds
to
manual
operation.
Each
pushbutton
of
the
front
panel
can
be
remote-controlled
by
applying
a
combination
of
two
ASCII
characters.
Figure
2-8
shows
the
association
of
the
different
programming
commands
with
the
ZPV
front-panel
controls.
The
on/off
buttons
are
disabled
by
a
letter
and
a 0
and
enabled
by
the
same
letter
and
a
1.
Example;
IQ
means
"filter
off";
II
means
"filter
on
.
In
addition
to
the
button
functions,
the
amplitude
ranges
of
the
amplifier
and
the
frequency
subranges
of
the
plug-in
can
be
programmed
in
accordance
with
table
2-10.
Thus
programming
simply
consists
of
a
sequence
of
ASCII
characters
corre-
sponding
to
the
order
of
buttons
pushed.
Table

gives
an
alphabetical
list
of
all
control
characters
accepted.
