8.6 Sequencer
8.6.1 Introduction
The sequencer feature allows you to apply different sets of configuration parameter settings, called
sequencer sets, to a sequence of image acquisitions. As the images are acquired, one sequencer
set after the other is applied. This makes it possible to quickly respond to changing imaging
requirements while acquiring images. For example, imaging requirements will change when the
illumination changes.
After camera startup or reset, the sequencer sets will be available with default parameter values
according to the settings of the default user set. Each sequencer set is identified by an index
number that can range from zero through 31. Accordingly, up to 32 different sequencer sets are
available.
To have sequencer sets available for your specific requirements, you will, however, usually want to
configure the sequencer sets. This will include changing parameter values to make them
appropriate for your requirements (see Section 8.6.3 on
page 222 ). To change the parameter
values of a sequencer set, you must first load the sequencer set into the active set. For more
information about sequencer configuration, see Section 8.6.3 on
page 222 . For more information
about the active set, see Section 8.17 on page 288 .
Sequencer Modes
The sequencer feature will be enabled when you set it to either of two different modes:

In the sequencer configuration mode , the sequencer sets can be configured but not be used
for image acquisition.
The sequencer configuration mode must be set to On and the sequencer mode must be set to
Off.

In the sequencer mode (also called "sequencer mechanism"), the sequencer sets can be
used for image acquisition but not be configured.
The sequencer mode must be set to On.
When the auto functions feature is enabled, the sequencer feature will not be
available. For more information about the auto functions feature, see Section 8.12
on
page 261 .
The sequencer feature is not available for the acA1920-155 camera.
