Decode Window - Honeywell 4800dr - Document Camera Barcode Manual

Decode Window

This feature defines an area or window within which a barcode must be placed in order to be decoded.
Although the aimer brackets are displayed over a wide area, you can define a smaller window for decod-
ing barcodes. This will improve decode time. Note that the barcode can only be decoded if it is entirely
within the defined window.
Setting a decode window does not change where the illuminated aimer brackets appear, so the user may
think the decode area is larger than it is. A user should center the barcode under the illuminated cross-
hairs to insure a proper read.
The decode window is based on the percentage of the field of view. The 4800dr defaults to Decode Win-
dow On, Decode Window X at 68%, and Decode Window Y at 60% (this emulates the decode area of
our other imaging products).
Default Decode Window Diagram:
If you want the decode window to use the full field of view, scan the Decode Window Off (Full FOV) bar-
code. (Note that this slows decode time.)
To set a decode window, scan the Decode Window On barcode. Next set the percentage of the field of
view for the window by scanning the Decode Window X barcode and scanning up to 3 digits from the
inside back cover this manual to set the percentage of the field of view for the X setting. Scan the
Decode Window Y barcode and scan the digits for the percentage of the field of view for the Y setting.
