Parameters and commands
Consequently, any exposure time setting controlled by Parameter
E
or by exter-
nal signal is ignored.
The light should flash between two image readouts, which may be the duration
of one line at highest possible image rate.
Decrease the image rate accordingly, if longer exposure times are needed. Use
the sync output (RS232 driver at pin 6) for synchronization.
Permanent exposure mode
Bit group: f
Weight: 20
Use this mode to maximize the exposure time.
If activated, the exposure time equals the image duration.
Consequently, any exposure time setting controlled by parameter
E
or by exter-
nal signal is ignored.
Number of lines (N)
The number of lines per frame is controlled with
N
. The actual line count is N+1,
the default of
N=6BD
results into 1726 output lines. If the double ROI mode is
active (
D=1
) the actual line count is doubled: (N + 1) * 2.
Parameter
N
also has an influence on the number of frames per second possible.
Use the following formula to calculate the exact number:
•
Max fps = 1 / ((D + 1) * (N + 1) + 1 + IOD) * t
L
);
