F-10 Capture Mode
•Note: The range of maximum number of captures is dynamic. This range is dependent on the maximum image size in
the system. A full-size image (1280 x 1024) reduces the maximum number of images to 6. The smaller the image size,
the greater the maximum number of captures. Once the image size is reduced to small enough dimensions, the
maximum number of captures will be capped at 64.
If a user enters a maximum capture value greater than that allowed, the value will be limited to the
number of system images. This command also affects the number of stored images allowed in the
system. If the maximum number of captures is selected, the number of stored images allowed will be 0.
Definition: Capture Mode relates to the way that images are captured and processed.

Rapid Capture
Definition: In a rapid capture mode, one or multiple captures (as many as 32) can be
taken at an interval specified by the time-between-captures parameter. In
this mode, the only limiting time factor is integration and transfer timing.
Continuous Capture
Usage: Continuous Capture is useful in applications with slower line speeds or
where symbol spacing may be random or not time-dependent.
Definition: In Continuous Capture Mode, image captures are taken throughout the
read cycle in a multi-buffered format (see diagram below). The reader
begins processing the first captured image at the same time that it captures
the second image. Captures will continue occurring throughout the read
cycle until an end condition occurs, such as a timeout, a new trigger, the
last frame in a capture sequence, or a combination of the above.
F-10-1 Number of Captures
Usage:
Number of Captures
is used to specify the number of captures to be processed
in Rapid Capture Mode.
Definition:
Sets the total number of captures that are processed during a read cycle in
Rapid Capture Mode
. This feature is used in conjunction with
Capture Timing
parameters to specify the capture sequence of a rapid capture read cycle.
