6.2.2 Picket-Fence Mode
If scanning is parallel to the code motion, (Figure 75), the number of effective scans is given
by the following formula:
SN = [((FW-LW)/LS) * SS] -2
Where:
SN = number of effective scans
FW = reading field width (in mm)
LW = label width (in mm)
LS = label movement speed (in mm/s)
SS = scans per second
Figure 75 - "Picket-Fence" Scanning Mode
For example, for a 60 mm wide code moving in a point where the reading field is 160 mm
wide at a 2000 mm/s speed, the DS5100 (800 scans per sec.), performs:
[((160-60)/2000) * 800] - 2 = 38 effective scans
