F-10-2 Rapid Capture Mode
Definition: In 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.

Default: Timed Capture
Options:
0 = Timed Capture
1 = Triggered Capture
Timed Capture
Usage: Timed Rapid Capture is useful in fast-moving applications in which symbols
are only in the field of view for a short time and precise timing is required.
Definition: In Timed Rapid Capture, decoding occurs independent of and simultaneous
with capturing, thus allowing precise timing or no delay at all between
captures.
Also, consecutive captures are regarded as the same symbol if the output
data is the same.
Triggered Capture
Usage: Useful in applications where each decode must be treated as a discrete
event, regardless of symbol data.
Definition: The first trigger event starts the read cycle, and subsequent triggers will
continue until the predetermined Number of Captures is met, or until the
predetermined End of Read Cycle condition is met-- whichever occurs first.
Note: If End of Read Cycle is set for New Trigger and the read cycle
qualifications have not been met, the read cycle will only end once it
receives the first trigger after reaching the predetermined Number of
Captures setting.
