Note
If Frame Start Trigger is input from TTL IN
1
(
) is the phase relation between the
exposure time and FVAL inside camera
If Exposure Time = 10.
( ) is the exposure time inside camera
If Binning off and Height=3840
(Varies by the vertical ROI)
If Exposure Mode = Timed
This may vary by binning setting and ROI
setting. The phase of Frame Active End
Edge may vary by 1us against FVAL Active
End.
Exposure Active at TTL I/F output
( ) is the exposure phase relation inside
camera
If the polarity is Active High
If the polarity is Active High
