22. The
Gain
and
Offset
for Twelve-bit digitization mode can be changed from their factory values: you must
unclick the
Defaults
button to unlock the edit boxes. The Gain for Sixteen-bit mode is not adjustable, but its
value is displayed. You can also indicate whether to
Digitize Overscan
(the part of the CCD sensor
surrounding the imaging area which is covered by an opaque mask). In some applications the overscan
region is used as part of the calibration process.
23.
Post-Exposure Delay (s)
allows you to set the time delay at the end of the exposure, in seconds. The time
delay ensures that the shutter is completely closed before readout commences. For certain camera models
this may be fine-tuned to accelerate readout; please contact us for more information.
24. Use the
Kinetics Parameters
to specify the
Section Height
in pixels and the
Number of Sections
; these
values will be determined by how your CCD chip is masked. Set the
Rate
to the time interval in seconds per
section. Note that the timing implied by these controls takes precedence over the exposure time specified
elsewhere in MaxIm DL.
25.
Flush Vertical Binning
allows you to override the vertical binning factor used during camera flushing.
Ordinarily you should use the
Default
setting.

. If Ethernet, you must specify a
Network Mask
, which limits the subnet that is
searched.
27. When you click
Search...
the software will generate a list of available cameras, if any. You can select the
camera by clicking on it in the
list
and then clicking
OK
.
