7.2.2 Picket-Fence Mode

If scanning is parallel to the code motion, (Figure 106), 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 106 - "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 1500 mm/s speed, the DS2100N (500 scans per sec.), performs:

[((160-60)/1500)

500] - 2 = 31 effective scans
