READING FEATURES

For example, the DS2200 (500 scans/sec.) for a 25 mm high code moving at 500

mm/s performs:

[(25/500)

500] - 2 = 23 effective scans.

3.2 PICKET-FENCE MODE

Direction of code

movement at LS speed

DS2200

Figure 17 - "Picket Fence" scanning mode

If scanning is parallel to the code motion, (Figure 17), the number of effective scans

is given by:

SN = [((FW-LW)/LS)

SS] -2

These symbols signify:

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

For example, for a 50 mm wide code moving in a point where the reading field is 100

mm wide at a 1000 mm/s speed, the DS2200 (500 scans per sec.), performs:

[((100-50)/1000)

500] - 2 = 23 scans
