label is in the read range of the scanner. When To Output options have no affect on
Continuous Read. Continuous Read is useful in testing label or scanner functions.
Continuous Read 1 Output
Note:
Enabling Continuous Read 1 Output when Number of Labels (
) is set
to any number greater than one will cause Number of Labels to default back to one.
Label data is immediately transmitted once every time new label data is placed in
front of the scanner. With Timeout enabled for End Of Read Cycle, if the label doesn't
change, the scanner will repeat the output at the end of each subsequent timeout
period. For example, if Timeout were set to one second, the scanner would output the
label data immediately, and then repeat the output at intervals of one second, for as
long as the label continued to be scanned.
With Timeout disabled (that is, End Of Read Cycle set to New Trigger), the scanner
will output the current label data immediately, but output it only once. A new label
appearing at any time in the scan range will produce a new read output as long as the
new label is not identical to the previous label.
External Level
1
Allows a read cycle to be initiated by a trigger signal from an object detector when an
object appears within the detector’s range. The read cycle exists as long as the detec-
tor “sees” the object and does not end until the object moves out of the detector’s
range even if a good read or timeout occur sooner (
).
Figure 2-5 External Level Trigger Signals

Level
and
Edge
apply to the active logic state (positive or negative) that exists while the object
is in a read cycle, between the rising edge and falling edge.
Rising edge
is the trigger signal
associated with the appearance of an object.
Falling edge
is the trigger signal associated with
the subsequent disappearance of the object.
Second trigger
1
The same object, moving out of the detector's beam,
causes a second trigger (falling edge trigger) signal to
be sent to the scanner, ending the read cycle.
Object
detector
First trigger
An object, moving in front of the detector beam,
causes the first trigger (rising edge trigger) signal to
be sent to the scanner, initiating the read cycle.
