Timed Rapid Capture
is useful in fast-moving applications in which codes are only in the field of view
for a short time and precise timing is required to read all the codes. In this mode the read cycle starts
with an initial trigger. During the cycle, the reader will continuously acquire new captures based on the
time between captures
and place them in a buffer. Each buffered image will be processed in turn until
all symbols are found, all captures are processed, or the
timeout
is reached.
The
time between captures
can be set to very small intervals, such that the reader can capture all
images on a small or very fast-moving part. It is typically set to a longer interval to be able to catch all
the codes on larger parts, or on slower-moving lines. Refer to
Image Buffering and Pipeline
Processing
above.
Serial Trigger Character
– Sets the serial input trigger character. The reader will also respond to an
edge change on the physical trigger input.
Trigger Before 1st Capture
– This is the amount of time between when the trigger is received and
when the unit takes the first picture. This is useful for adjusting code position on a moving line.
