Description
Read mode
Single
– When a barcode has been decoded, the barcode reader will be
turned off. The reader needs to be triggered again to decode another
barcode.
Multiple
– When a barcode has been decoded, the barcode reader will
stay on for a time set by read time. The decoded barcode cannot be
scanned after the decoded barcode has not been detected for a
number of scans.
Read time
The time that the barcode reader is on after a trigger has been pressed
or when a barcode is decoded in multiple read mode. The read time is
set in seconds
Margin check
With the margin check option the specified margin before the start
and end of the barcode can be made smaller. Setting the margin to a
too small setting may increase or trigger partial or ghost reads. Do not
use a smaller margin check then necessary. If possible replace the
barcode label that have a correct start and stop margin.
Redundancy
This is the number of times that a barcode label needs to decoded
again after a successful decode. Setting redundancy to 1 means that a
barcode is decoded twice.
Positive
Positive barcodes are black bars on a white surface.
Negative barcodes are white bars on a black surface.
Both possibilities to decode positive and negative barcodes.
Scan
Set the scan width of the 1D laser module. This option is not supported
with a 2D imager.
