Setting this parameter to on keeps image capture active and continuously decoding as long
as the scanner button is pressed and held down.
Center Barcode Only
When more than one bar code is visible in a single snap shot, this parameter allows you to
specify that only the centre image within the imager framing marker be read. When this pa-
rameter is set to on, the target dot is pointed at the centre image and only that image is
returned.

Specifies the maximum number of bar codes the imager attempts to decode in an image. A
maximum of 6 bar codes can be decoded at one time.

This parameter specifies the minimum number of bar codes that the imager must decode in
order to report success.
