Parameters and Commands
Bonito Technical Manual
V2.2.1

Trigger source selection (T)
This parameter selects the signal source for triggering and exposure control.
For more information about usage of the selected signals: see Chapter
Exposure
control mode (M)
on page 40.
Metadata overlay and test image generator (U)
The Bonito can overlay the image’s first pixels with some bytes of metadata,
such as a hardware frame counter. The frame counter increments for each image
read out from the sensor. This helps to increase system reliability by detecting
missing frames on the host system. In dual channel mode (
S=1
or
S=3
) it can
also be used to join the two related image halves because they have the same
counter value.
Furthermore, to test the Camera Link cabling and frame grabber operability, a
test image generator is available. It forces the camera to output an almost fixed
test image containing grey wedges, black and white stripes with various fre-
quencies and edge markers.
S=7
Same as mode 3, but with right image half via O2/O1 and left
image half via O4/O3 (if available).
