Configuration of the camera
Enabling this feature, time stamp data will be inserted into any captured image.
The size of the time stamp depends on the selected time stamp format.
The LinePos field indicates at which line the stamp will be inserted.
Enter a
• positive value from 0..HeightOfImage to specify a position relative to the
top of the image. LinePos=0 specifies the very first image line.
• negative value from -1..-HeightOfImage to specify a position relative to
the bottom of the image. LinePos=-1 specifies the very last image line.
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.
