+--s: Suppression of new data acquisition. This bit
is write-only and reads always 0. Write C=3 to
reactivate the fixed pattern noise correction
from the state C=0 without the correction data
being reacquired as C=1 would do.
D= : Double ROI mode. Can be used to read out two independent
areas of the same size into one output image. This is useful
to gain speed due to dropping unneeded lines between two
areas of interest. Also field separation for interlaced mode
can be obtained. The top half of the output image consists
of the lines A, A+I, A+2*I, ..., A+N*I and the bottom half
consists of the lines B, B+I, B+2*I, ..., B+N*I. the
resulting image size is (N+1)*2. Please see parameters
A=, B=, I= and N= for more details.
0: Single ROI mode. Image size is (N+1) lines.
1: Double ROI mode. Image size is (N+1)*2 lines.
Parameter B= specifies the address of the first
line of the second half. Please note that due to the
increased image size (N+1)*2 also the minimum frame
duration increases from (N+1) + 1 to (N+1)*2 + 1.
E= : Exposure time. The time resolution depends on the prescale
value K=. Please note that the exposure time is only
active when the trigger mode M= is set accordingly.
F= : Frame duration. The time resolution depends on the prescale
value K=. Please note that the frame duration is only
active when the trigger mode M= is set accordingly.
G= : Digital gain.
0: Gain factor 1.
1: Gain factor 2.
2: Gain factor 4.
I= : Increment value of the line address counters A and B. After
processing each line this value is added to the current line
address. Valid range 1...FF (decimal: 1...255).
J= : Configuration of synchronization output at pin 6 of the
control connector. This pin delivers RS232 voltage levels
(+/- 6 volts) with a delay of less than 800 ns. The logic is
negative, meaning +6 V = LOW and -6 V = HIGH.

| +-s: Signal source selection.
| 0: Effective sensor exposure.
| 1: Charge transfer pulse. Active for one line
| duration at the end of exposure, end of
| this pulse marks the end of exposure and
| at the same time start of sensor readout.
| In PIV mode (see M=) this pulse occurs
| at the exposure end of only the first
| image of each PIV pair.
| 2: Effective sensor readout.
| 3: Exposure phase. Contrary to 0 this setting
| shows the "exposure phase" of the state
| machine and not the effective exposure
