Sequencer Function - JAI GO-5100MP-USB User Manual

Sequencer Function

The Sequencer function lets you define up to 128 index combinations of exposure time, gain,
ROI, and other settings which can be stepped through each time a trigger is received.This is
particularly useful for quickly capturing multiple exposures of objects under inspection to adjust
for areas or components with significantly different levels of reflectance. You can specify the
next index in the stepping sequence and the order in which indexes are executed. Multiple
indexes can also be executed repeatedly.
Two operation modes (TriggerSequencer mode and CommandSequencer mode) are available
for the Sequencer function.
Note
The following four conditions must be met to use the Sequencer function.
1. [PolarizeImageSelector] is [RawImage].
2. Sequencer Width, Sequencer Offset X function, and Sequencer H Binning function
cannot be used at the same time.
3. Sequencer Height, Sequencer Offset Y function, and Sequencer V Binning function
cannot be used at the same time.
About indexes (imaging conditions)
Up to 128 indexes can be configured.The following settings can be configured for each
index. However, SequencerFrameNumber and SequencerSetNext can only be configured
in TriggerSequencer mode.
Trigger Sequencer mode
With this mode, the Sequencer Trigger "pattern" is predetermined by the user. The user
defines up to 128 different "indexes." The items indicated in the above index can be
configured for each index. The operation of this mode is controlled using the following five
commands.
[SequencerSetActive]
This allows you to confirm the currently configured index number.
[SequencerSetStart]
This configures the index number to execute at the start of TriggerSequencer mode.
[SequencerReset]
During TriggerSequencer mode operation, this switches the index number to be executed to
that specified in [SequencerSetStart].
[SequencerRepetition]
This parameter applies to TriggerSequencer patterns which include an index whose
[SequencerROINextIndex] is set to 0 (OFF).When the index whose [SequencerROINextIndex]
is set to 0 (OFF) is finished executing, the value of Sequencer Repetition (range = 1-255) is
decremented internally. If the result of the decrement is not zero, the TriggerSequencer
pattern starts over from the index specified in SequencerSetStart. If the result of the
decrement is zero, the status changes to Acquisition Stop and external triggers are not
accepted.
