For example, the DS41 (800 scans/sec.), for a 25 mm high code moving at

1250 mm/s performs:

3.2

PICKET FENCE MODE

If scanning is parallel to the code motion, (Figure 3.2 - "picket fence" mode),

the number of effective scans is given by:

SN = [((FW-LW)/LS) * SS] - 2

These symbols signify:

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

field is 250 mm wide at a 1500 mm/s speed, the DS41 (800 scans per sec.),

performs:

3.2 - Reading features

[(25/1250) * 800] - 2 = 14 effective scans.
