Psion Teklogix 7530 G2 Max Number Barcodes, Barcodes Must Decode, Window Width, Window Height

Chapter 5: Configuration

Imager

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

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.

Barcodes Must Decode

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

This parameter 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.
