This map shows the field of view of the DataMan 300 series readers
with a 16 mm lens.
The FOV values are shown as follows:
• outer: DM302, DM303
• inner: DM300
The reading distances for the DM300 and DM302 readers are the
same. DM303 features a higher resolution and more pixels in about
the same sensor size.
To make sure that your DM303 reader is able to decode at the
minimum reading distances, use the reader in combination with the
extension kit or without the front cover.
The following table shows the Field of View widths in mm at various
distances.
