Refer to the diagrams given in
Reading Diagrams
on page 45 for further details on the reading features. They are taken
on various resolution sample codes at a 25 °C ambient temperature, depending on the conditions in the notes under the
diagrams.
9.3.3 Raster
Raster versions are available. The distance between the top and bottom scan lines is called capture and is measured from
the laser beam output window. The reading characteristics for the raster versions for the TCNM-EX Barcode Scanner are
given in the table below:
Reading Distance
300 mm (11.8 in)
600 mm (23.6 in)
Raster Capture
18 mm (0.7 in)
35 mm (1.4 in)
The maximum capture of the TCNM-AD Barcode Scanner is 18 mm (0.7 in) at 300 mm (11.8 in).
