Restrictions Note the restrictions in the following table. When using software with an
Isochronous Resource Manager (IRM): deactivate it.
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 sup-
ported isochronous packet size. Use this flag to query the maximum sup-
ported 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 isn’t lower than the value specified by the IEEE1394
specification.
The settings are stored in the user sets.

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.
