Integrating the Scanner to Read at the Proper Dis-
tance
When deciding how to mount the OEM scanner, there are many criteria
that must be considered. First, there are minimum and maximum dis-
tances that the bar code can be from the front of the scanner to be prop-
erly read, depending on the size of the bar code. These distances, or depth
of field, are specified in
"Technical Specifications" on page 17.
The scanner must be positioned so that the scan volume and illumina-
tion light will cover the entire bar code. The scan volume is shown in
Figure 9 . The combination of the Scan Volume and the illumination
light is called the Field of View. Designing around the scanner Field of
View is explained more in the following section.
