Read Cycle
Image Storage
Image Storage Type
Disabled/Clear
Upon selection of this option, all saved images will be cleared and the reader will not store
images for later viewing.
Store on No-Read
This option will cause the reader to store an image upon exiting the read cycle for retrieval
at a later time. If multiple captures are present during the duration of a read cycle, the
stored image will be the last image processed for that read cycle. This image is stored in
RAM and can be retrieved as long as power is cycled to the reader, and as long as the
reader has not been reset via a reset/save sequence. Other commands that can initialize
storage in RAM are ones that change capture modes or put the reader in a test capture
mode.
Image Storage Mode
First Mode
This mode allows the reader to store images until the available image memory has been
filled. At that point the reader will stop saving additional images. In this mode, you will
always have the first image captured, because the saving process stops once memory
has been filled.
Last Mode
In this mode, image storage continues after available memory limits are reached. The oldest
image in memory is overwritten, so you will always have the most recent stored image.
Definition: Allows the user to store images from separate read cycles and to retrieve
them later. The number of available slots for storage depends on the mode
of operation. If the reader is in Rapid Capture Mode , the number of
images that can be stored is equivalent to the maximum number of the
rapid count (the current rapid count setting). If the reader is in Continuous
Capture Mode , a number of images equivalent to the maximum number of
the rapid count minus 3.
