Linear Scan Parameters
Select: To:
Scan Width Change the width of the scan beam by varying the angle at
which the beam exits the Reader. Select from 30, 40, 50, 60,
70, 80, 90 or 100% of the maximum scan angle. The maxi-
mum scan angle depends on the type of Reader.
Elevation Set the vertical angle at which the scan beam exits the Reader.
The elevation ranges from +10 to -10 degrees from the center-
line of the scan window.
Raster Scan Parameters
Select: To:
Scan Width Change the width of the scan beam by varying the angle at
which the beam exits the Reader. Select from 30, 40, 50, 60,
70, 80, 90 or 100% of the maximum scan angle. The
2755-SN8 scan beam cannot be set to less than 50% due to
CDRH requirements.
Upper Angle Set the upper scan angle of the raster pattern. Values range
from +10 to -10 degrees from the centerline of the scan win-
dow.
Lower Angle Set the lower scan angle of the raster pattern. Values range
from +10 to -10 degrees. The lower scan angle must be less
than or equal to the upper scan angle.
Increment Set the speed of the raster. Select a value between 0.1 and 1
degree per scan.
Flyback
Control Enable flyback which quickly returns the scan beam from the
lower raster limit to the upper raster limit.
