7.2.1 Step-Ladder Mode

If scanning is perpendicular to the code motion direction (Figure 77), the number of effective
scans performed by the reader is given by the following formula:
SN = [(LH/LS) * SS] – 2
DS2100N
For example, the DS2100N (500 scans/sec.) for a 25 mm high code moving at 1000 mm/s
performs:
76
Where: SN = number of effective scans
LH = label height (in mm)
LS = label movement speed in (mm/s)
SS = number of scans per second
Figure 77 - "Step-Ladder" Scanning Mode
[(25/1000) * 500] - 2 = 10 effective scans.
