Two different scanning mode options are available to help prevent adjacent barcode reading in
applications where more than one barcode is present in the DLL2020 laser pattern (i.e. this
manual). These options are:
- Freeze Frame Mode
- Single Line Mode (DLL2021 only).
- the Freeze Frame mode is a special trigger mode allowing to aim the laser pattern onto the
specific code before reading.
To use this mode:
1. Press and hold the scanner trigger. The laser pattern starts blinking but the scanner does
not read the code;
2. Move the scanner towards the barcode (zoom-in);
3. Release the trigger to read the barcode.
- the Single Line mode is a special trigger mode which temporarily switches the full scan pattern
to a single scan line which can then be aimed onto the specific code before reading.
To use this mode:
1. Press and hold the DLL2021 trigger to switch from the full scan pattern to a single scan line;
2. Aim the single scan line onto the barcode to be scanned making sure the line completely
crosses the barcode;
3. Release the trigger to read the barcode.
Both these scanning modes are in addition to the normal omni-directional scanning pattern
which is always available for barcode reading.
CONFIGURATION PROCEDURE
1) Read the "Enter/Exit and Save Programming Mode" code in Appendix C;
2) Read the Scanning Mode code;
3) Read either the Freeze Frame Mode code or the Single Line Mode code;
4) Read the "Enter/Exit and Save Programming Mode" code again.
