Forward/Reverse
Forward/reverse information has to be set correctly as soon as one of the following modes : “2S”, “4S”
or 2SB of the sensor is set.
In these modes, the sensor/Camera need to know what is the real order of the lines for the exposure
delays.
The Forward direction is defined as detailed below :
Note
: The minimum delay for the Camera to take in
account a change in the ScanDirection value is :
-
Using CC3 (I/O) signal :
120ms
.
-
Using serial (register) command
(*)
:
180ms
(*)
After reception of the Command on the camera side
If the Camera is in
4S
Sensor mode, after changing of the
scanning direction, the 5 first following triggers will be
ignored in order to reinitialize the “Full Exposure Control”
mode. Then the 3 following lines acquired will be more or less
black because in 4S, 4 lines are required for a complete
exposure.
In
2S or 2SB
Sensor modes, no Trigger will be lost after
the change of scanning direction but the first line acquired
will be more or less black as in 2S, 2 lines are required for a
complete exposure.
In
1S
or
1SB
modes, nothing is lost an all lines received
after the delay are correct.
This positioning takes also in account that the mode “Reverse X” is “Off” (Normal readout direction)
