Imager
Center Bar Code Only
Note: This parameter must be disabled when reading Composite bar codes.
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 parameter is set to on, the target dot is pointed at the centre image and
only that image is returned.
Max Number Barcodes
This parameter specifies the maximum number of bar codes the imager will attempt
to decode in an image. A maximum of 6 bar codes can be decoded at one time.
Barcodes Must Decode
This parameter specifies the minimum number of bar codes that the imager must
decode in order to report success.
Note: This number must be less than the number of bar codes assigned to
"Max Number Barcodes". The driver validates and reassigns the value
if necessary.
Window Width
"Window Width" determines the width of the captured image in pixels.
Note: The driver will validate and reassign the value assigned to this parameter,
if necessary; the driver will also use the Window Width value to horizon-
tally center the image in the field of view.
Window Height
This parameter determines the height of the captured image in pixels.
Note: The driver will validate and reassign the value assigned to this parameter,
if necessary; the driver will also use "Window Height" value to vertically
center the image in the field of view.
Dot Time (msec)
The value selected for "Dot Time (msec)" determines (in milliseconds) how long
the targeting dot remains on before the scanner begins capturing images. When you
double-tap on this parameter, a dialog box is displayed in which you can enter a
value of between 0 and 3000. A value of 0 disables the target dot.
