CHAPTER 3 DATA CAPTURE

The SB1 contains a bar code reader with aimer and illumination for reading bar code data. The reader uses

digital camera technology to take a digital picture of a bar code, stores the resulting image in its memory, and

executes state-of-the-art software decoding algorithms to extract the data from the image.

Scanning consists of; aim, scan and decode. Scanning performance can be optimized by considering the

range.

Any scanning device decodes well over a particular working range (minimum and maximum distances from the

bar code). This range varies according to bar code density and scanning device optics.

Scanning within range brings quick and constant decodes; scanning too close or too far away prevents

decodes. Move the SB1 closer and further away to find the right working range for the bar codes being

scanned. The best way to specify the appropriate working range per bar code density is through a chart called

a decode zone. A decode zone simply plots working range as a function of minimum element widths of bar

code symbols. See the SB1 Integrator Guide for decode zone chart.

NOTE Contact the Motorola Solutions Global Customer Support if chronic scanning difficulties develop.

Decoding of properly printed bar codes should be quick and effortless.

To read bar codes:

Ensure that the SB1 is loaded with a scanning application.

Aim the exit window at the bar code.
