Single Line Mode - Datalogic CATCHER D531 Series Quick Reference

SINGLE LINE MODE

When many barcodes are present in the same reading area, like in barcode
price lists or in the case of configuration barcodes in this manual, selecting a
specific barcode to read is not practical with the large raster pattern emitted by
the Catcher™, so a special single line scanning mode can be easily entered to
perform this task. In this mode only a single scanning line is enabled so that
aiming and reading barcodes become very easy.
To use single line mode for barcode reading follow the procedure below:
1. While the normal raster pattern is present, press the trigger. A single laser
line will appear but barcodes cannot be decoded.
2. Position the presentation scanner over the code to read and press the
trigger within 5 seconds to decode the code.
When using the scanner for data entry, a programmable timeout is provided to
assure that Catcher™ will return to raster mode if barcode reading is not
successful in single line (Single Line Decoding Duration). Also a programmable
timeout is available to manage how long to wait after successful reading before
returning to raster mode (Single Line Timeout OFF Before Raster).
If you need to make consecutive readings in single line mode, simply repeat the
procedure before the Single Line Timeout OFF Before Raster expires.
When in configuration, Catcher™ will remain in single line until the Exit
Configuration barcode is read.
