Reading Parameters
31
Selections:
Disabled
the laser is always on.
Enabled
the laser is always off and all operations are suspended.
Triggered
the laser is turned off as soon as the code(s) are read or when the reading phase ends.
The laser is turned on again when the next reading phase starts.
NOTE
The
Triggered
selection is ignored for Automatic and Test Operating Modes.
Required Quiet Zones
For Linear reading, with fixed length codes or fixed bar counts, the Quiet Zone requirements can be defined.
Selections:
Both
Both Quiet Zones must be present adjacent to the code (Normal condition for all
code reading).
One
Only one quiet zone must be present adjacent to the code.
Overflow Ratio
This parameter defines the minimum expected width of the barcode quiet zone, expressed in number of modules. If
the barcode quiet zone is less than the expected ratio, the barcode will not be decoded.
Selections: a value between
3
and
32
for Linear reading.
Overflow Start/Stop Ratio
For the TCNM-SP family, if working in Reconstruction reading mode, this parameter defines the minimum expected
width of both the beginning (Start) and ending (Stop) barcode quiet zone, expressed in number of modules. The Start
and Stop Ratios can be different from each other. If the specific barcode quiet zone is less than the expected ratio, the
barcode will not be decoded.
Selections: a value between
1
and
50
for TCNM-SP Reconstruction reading.
Reading Mode
It defines the scanner reading mode:
Selections:
Linear
standard reading mode - the scan line must intersect the entire code.
Reconstruction
allows code reconstruction when reading the code
TCNM-AD/EX - the scanner works in ACR-Lite (Advanced Code
Reconstruction) mode in which several partial scans of a barcode are
added together to reconstruct the code information. This allows code
reading at more acute tilt angles (however less than ACR4™) and
improves reading percentage of some damaged codes.
TCNM-SP - the scanner works in ACR4™ (Advanced Code Reconstruction)
