Configuration Database
Database and Capture Modes
The configuration database behaves the same for both "Rapid" and "Continuous" Capture
Mode, the only discernable difference is in "Rapid" capture mode the database incrementing
always operates in "Number of Image Frames" with a "frame count" of 1.
Camera Settings
When the database loads a camera configuration and there is a change in shutter speed
(integration time), window of interest (WOI), or sub-sampling from the last image that was
captured; Then one image frame needs to be processed to setup the new configuration
prior to capturing an image.
The capture will start immediately following the integration period.
If the image dimensions are configured as a Region of Interest (ROI), then a change to
these values does not incur the additional image frame since it is no longer a camera setting.
Since some image capture events require that an image frame delay occur and some
don't, this does complicate the image capture time when the Configuration Database is
enabled.
Notes:
• If no camera change occurs, the start of the image capture is immediate upon being
triggered
• If a camera change occurs, the start of the image capture occurs after the shutter time
has completed. In the case above, the image capture would incur a 1ms delay.

Number of Active Indexes

Number of database records (groups of settings) that will be used automatically during the
read cycle. If set to 0, the imager only uses the current settings, not database entry settings.
Sort Database
Activates a sort function that move the database entry associated with the last decode to
the first position in the database and move all other entries up.
