Second, 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
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, .

Design of the Scanner Opening
A typical system uses the scanner mounted inside a host enclosure with an
opening for the scanner Field of View to exit the scanner window and read bar
codes. If the scanner is flush against the opening, it should be the size of the
scanner window at a minimum, but only exposing as much of the front surface
of the scanner as necessary. Additional clearance in the opening can also be
considered for the speaker opening.
The design and placement of the scanner opening within a host enclosure is
critical for optimum system performance. Use the detailed dimensions shown in
Appendix B, Mechanical
ner opening along with the following guidelines.
•
The opening must not block any of the outgoing illumination light,
described by dimensions of the scanner Field of View.
Ensure that there are no reflective surfaces around the area of the scanner
•
opening.
•
The minimum opening size must increase as the distance between the
scanner and the window increases. This is necessary to accommodate the
width and height of the scan volume.
•
The opening or other parts of the host enclosure must not enter the Field
of View in order to allow the bar code image to be captured by the scan-
ner.
If all the red illumination LED's remain on when the scanner is installed in the
host enclosure, then something is blocking the Field of View.
