READING FEATURES

For example, the DS2100 (350 scans/sec.) for a 25 mm high code moving at 500

mm/s performs:

[(25/500)

350] - 2 = 15 effective scans.

3.2 PICKET-FENCE MODE

If scanning is parallel to the code motion, (Figure 29), 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 29 - "Picket-Fence" scanning mode

For example, for a 50 mm wide code moving in a point where the reading field is 200

mm wide at a 1500 mm/s speed, the DS2100 (350 scans per sec.), performs:

[((200-50)/1500)

350] - 2 = 33 scans
