Overview of IP Database
Operation of IP Database
Once IP Database is enabled, the reader’s current settings for Shutter Speed, Gain,
Threshold Mode, Fixed Threshold Value, Processing Mode, Background Color, and
Narrow Margins will no longer impact reader operation. For those parameters, only settings
that are in the database will be used for image capture and processing.
When in IP Database mode and at the end of a read cycle or a calibration routine, if a
decode has occurred, the settings that were applied to that decode will move to the top of
the database. For example if a decode occurred using the 4th configuration index, it would
be moved to index #1 and the configurations preceding index 4 would be moved down one
slot as illustrated below:
When changing database settings, it is not always necessary to re-capture an image. If
the new configuration changes a camera parameter, then it is necessary to re-capture an
image. The capture mode selected (Rapid or Continuous) also has an impact on whether
a new image needs to be captured. The following summarizes the operation of the reader
for the two different capture modes when the IP database is enabled.
Usage:
Useful in applications in which a variety of symbol conditions require different
settings that can be applied in real time.
Definition:
Up to 10 multiple camera/image processing settings can be saved to a
database and be applied sequentially during operations.
