Parameter-List Update
In

Update
mode
a
complete
list
with
IIDC
addresses
and
values
of
up
to
64
parameters
is
sent
to
the
camera.
•
Host
sends
a
list
with
parameters
to
the
camera
(advanced

space)
•
Microcontroller
processes
that
list
•
All
parameters
will
become
active
for
the

(QFCM):

After

all

are

Frame

is
constant.
After
the

a

is
interrupted.
A

will
be

of

is

There
may
be
a

between
two

but

are
