Key to successful decoding
In PL3000 the imager does the ID symbology recognition and decoding. The reason why it is called an
imager is because it is actually a camera that captures the still images and interprets them (when scanning
is activated by pressing the scan-key). If the imager can recognize and decode the ID symbology it stops
the scanning and returns the value to the active program.
The successful decoding of the ID symbology requires that all the following conditions have met.
1.
The ID symbology (barcode or 2D code) is printed with good quality.
2.
ID symbology is supported by the imager
3.
ID symbology is in Depth of Field (see table ) and the size of the ID symbology doesn’t exceed the
Width of View.
4.
Lightning and contrast conditions are in met.
The imager performs best in the presence of at least 535 lux, (50 fc) of ambient light. Codes printed on
glossy or laminated paper are best read at angles greater than 5° in relation to the scanner. This prevents
the bright illumination reflections from being returned to the scanner.
