Decode Window

Decode Windowing is a functionality which allows defining a limited area within the scanner's
Field of View, where to look for a barcode, to improve performance.
The idea is that instead of having to search the whole full-sized image for a bar code, the
decoder only has to focus on a smaller area, thereby increasing the performance.
As long as the barcode or barcodes are within the boundaries of the Decode Window, they can
be decoded, when Decode Windowing is enabled.
If the barcode is outside the Decode Window, it will not be decoded.
Scan one of the codes below to enable or disable Decode Windowing. Default = Disabled.
Enable Decode Windowing
To define the Decode Window, one needs to set the boundaries for Top, Bottom, Left and Right.
These boundaries are defined by pixel values within the full frame (e.g. 844 x 640 pixels).
Note: There are automated restrictions to prohibit a 'negative' Decode Window size. This means
that the Bottom value cannot be 'above' Top and likewise for the values for Left and Right.

Decode Window Top/Bottom

The Top and Bottom boundaries for the decode window can be set either by sending the
serial command shown under the barcodes below with a value between 0 and 639,
or by scanning one of the barcodes below and then set the boundary pixel value by
scanning the digit codes and the SAVE barcode in
Please contact JADAK if assistance is needed.
Default Top boundary = WINDECT 256. Default Bottom boundary = WINDECB 384.
