Note

SIS outside the visible image area:

For certain Format_7 modes the image frame transported may

contain padding (filling) data at the end of the transported

frame. Setting LinePos=HeightOfImage places the stamp in

this padding data area, outside the visible area (invisible

SIS).

If the transported image frame does not contain any padding

data the camera will not relocate the SIS to the visible area

automatically (no SIS).

Take in mind that the accuracy of the time stamp might be

affected by asynchronous traffic – mainly if image settings

are changed.

The IEEE 1394 cycle counter will be inserted into the very

first 4 bytes/pixels of a line.
