Sequencer Function - IAI GOX-2402M-USB User Manual

Sequencer Function

The Sequencer function lets you define up to 32 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.
Caution
If the values of [ImageFormatControl] Width and Height are smaller than
[SequencerControl] SequencerWidth and SequencerHeight, the image may not be
output correctly.
When using SequencerWidth / SequencerHeght, set the Width and Height to the default
values in advance.
About indexes (imaging conditions)
Up to 32 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 32 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 index number displayed on next trigger
reception.
[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.
