Imager – Advanced Options
Barcodes Must Decode
This parameter specifies the minimum number of bar codes that the imager must decode in
order to report success.
Window Width
“Window Width” determines the width of the captured image in pixels.
Window Height
This parameter determines the height of the captured image in pixels.
Dot Time (msec)
The value selected for “Dot Time (msec)” determines (in milliseconds) how long the target-
ing 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.
6.10.4.2 Imager – Advanced Options
Factory Defaults On Reboot
The value assigned to this parameter determines whether or not the driver will restore the
factory defaults to the imager device on the next reboot.
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.
Note: The driver will validate and reassign the value assigned to this parameter, if neces-
sary; the driver will also use the “Window Width” value to horizontally center the
image in the field of view.
Note: The driver will validate and reassign the value assigned to this parameter, if neces-
sary; the driver will also use the “Window Height” value to vertically center the
image in the field of view.
Important: Do not adjust the advanced options without first consulting Psion Teklogix
technical support.
Note: The driver will default the imager device on a ‘clean’ reset, regardless of the value
of this parameter.
