Operation
The
maximum
allowed
isochronous
packet
size
can
be
set
separately
for
the
ISO
speeds
S400
and
S800.
Check
the
associated
Presence_Inq
flag
to
see
for
which
ISO
speed
this
feature
is
available.
Setting
the
Set2Max
flag
to
1
sets
the
MaxIsoSize
field
to
the
maximum
supported
isochronous
packet
size.
Use
this
flag
to
query
the
maximum
supported
size
(may
depend
on
the
camera
model).
Enable
this
feature
by
setting
the
ON_OFF
flag
to
1
and
the
MaxIsoSize
field
to
a
value
greater
than
the
default
packet
size.
The
camera
ensures:
•
that
the
value
of
the
MaxIsoSize
field
is
a
multiple
of
4.
•
that
the
value
is
not
lower
than
the
value
specified
by
the
IEEE1394
specification.
The
settings
are
stored
in
the
user
sets.

Note
Enabling
this
feature
will
not
change
the
MaxBytePerPacket
value
automatically.
The
camera
may
not
use
the
new
isochronous
packet
size
for
the
MaxBytePerPacket
value
until
a
write
access
to
the
desired
Format_7
mode
has
been
issued.
