Parameters and commands
M=7
activate PIV and free-running exposure mode using E and F
N=6BD
(0x6BD = 1725), readout 1726 lines
K=53
(0x53 = 83), sets prescaler tick length to 84 clock cycles, which cor-
responds to 1.5 μs
E=1
set small exposure time, although PIV has no exposure control, the
exposure time is needed to create valid internal timing sequence
F=D7F
(0xD7F = 3455), sets frame duration to 3455 prescaler ticks,
Result: frame duration = 3455 * 1.5 μs = 5182.5 μs, the minimum that is valid for
the above-mentioned example settings
Digital gain (G)
The digital gain setting controls shifting of the pixel bits. It selects the eight of
the ten digitizer bits that are output to Camera Link. Overflow is represented by
saturation to maximum.
Range
0
,
1
, or
2
Default
0

Example
G=0
1x digital gain
G=1
2x digital gain
G=2
4x digital gain
Line address increment (I)
The line address increment value I is added to the current address at the end of
each line read out from the sensor. Setting values > 1 will skip lines accordingly.
In conjunction with a reduced N this is useful to gain higher frame rates without
diminishing the field of view (also known as sub-sampling).
If the maximum line address has been reached before end of image readout, the
address will wrap around and restart from the beginning.
Range
From
1
to
FF
Default
1
Note
The frame duration control using this value is only active if the
trigger mode
M
is set accordingly. For more information see
