Suppress Beep On
Decode
0
0: Beep indicating decode before JavaScript processing
1: Call JavaScript without beeping to indicate decode
Normally, the Reader beeps as soon as decodes are read and
processes them via JavaScript if necessary after the beep. To enable
JavaScript to control the beep feedback, change this setting to 1;
this will suppress the beep; the JavaScript would typically beep if
the decode is valid or start another read cycle if it isn’t.
This setting does not suppress beeps for anything but a successful
decode event.

Target Tolerance
(percent)
640
(#1600)
Valid Range: 0 to 7FFFFFFF Percent
For the Reader to accept a barcode, the barcode must be within a
certain distance from the center of the image. The distance is
defined as a percentage of the barcode’s smaller dimension. For
example, with a 10 x 20 mm barcode and a setting of 150 (%), the
barcode must be within 15 mm of the center of the image.
Any value over #1000 is considered infinite tolerance, and no target
checking is performed.
