Command Sequencer Mode

This mode allows the user to vary the "pattern" of the sequence in response to external factors.
Changes in the sequence can be initiated manually or in a programmatic fashion as the result of data
from sensors/controllers or from the analysis of previous images.
In this mode, the user can define up to 128 different "indexes" each incorporating a combination of:
ROI (width, height, offset X, and offset Y)
l
Exposure Time
l
Gain Level (R/B Gain can also be configured on the color model)
l
Black Level
l
Binning Mode (monochrome only)
l
LUT Enable (whether or not to enable the use of LUT for this index)
l
The user must also enter a value from 1 to 128 in Command Sequencer Index. This indicates which
index to execute each time a trigger is received. The same index will continue to be executed for all
subsequent triggers as long as the value of Command Sequencer Index remains unchanged.
Changing the value of Command Sequencer Index to one of the other predefined indexes causes that
index to be executed in response to subsequent triggers. This mode of operation enables users to
develop applications that continually send new values to Command Sequencer Index in response to
external factors such as changing light conditions, different types or sizes of objects being inspected,
or other factors. This allows applications to change ROI, exposure, gain, etc., without being restricted
to a predefined pattern.
As with Trigger Sequencer, Sequencer LUT Mode defines whether Gamma or LUT is to be applied to
the sequence. If Gamma is selected, the Gamma setting defined in the camera's Analog Control
section will be applied to all exposures in the sequence. If LUT is selected, the LUT characteristics
defined in Analog Control will be applied to any index where Sequencer LUT enable has been set to
ON.
Sequencer Index Frame Count, Sequencer ROI Next Index, and Reset Sequencer Index are not used
in Command Sequencer mode and entered values are ignored.
