IP Database
Rapid Capture Mode
In Rapid Capture mode, a capture can occur during image processing. For this reason it
is not possible to modify any image processing or decode parameters in this mode and
only camera configuration settings in the database will take effect. The following IP database
settings are not applied while in Rapid Capture mode: Threshold mode, Fixed Threshold
Value, Processing Mode, Background Color and Narrow Margins.
In Rapid Capture mode, when a reader enters the read cycle, it uses index 0 settings of
the IP database for the 1st image capture. For each successive capture the IP database
index is incremented and the new settings are applied to the new capture. A new capture
is acquired for each database configuration. When the last active database index is filled
and there are more captures to take, the index will start back at 0.
Continuous Capture Mode
When IP database is enabled (whenever Database Size is not equal to 0), Continuous
Capture no longer works in a double-buffered format. When the read cycle begins, the
reader enters uses index 0 settings of the IP database for the 1st image capture. The
reader will capture and decode the image, and increment the database index and apply
the new configuration. If the new configuration does not change camera settings, then a
new image is not acquired and the reader will try to decode the current captured image
with the new image processing settings. If the camera settings have changed from the
previous settings, then a new capture is required. When the end of the active database
configuration has been reached, the index will start back at 0.
