Scanner Settings C - 11

If you’re using the keyboard:

• Highlight the barcode you want to work with, and press the [RIGHT] arrow key to display the sub-menu.

• Use the [UP] and [DOWN] arrow keys to highlight a parameter.

• To change a parameter value, press [SPACE] or the [RIGHT] arrow key. If a field requires text entry, a text

box is displayed in which you can enter the appropriate value.

Options

• Tap on the + sign next to Options to display these parameters.

Dot Time (msec)

The value selected for “Dot Time (msec)” determines (in milliseconds) how long the targeting dot remains on

before the scanner switches to a normal scan sweep. When you double-tap on this parameter, a dialog box is

displayed in which you can enter a value from 0 to 3000. A value of 0(zero) disables the target dot.

Short Code

When enabled, this parameter allows scanning of short I 2 of 5 barcodes (2 characters). When disabled, these

short barcodes are rejected.

Enabling “Short Code” may reduce the robustness of the decoding since the hand-held must decode more

potential barcodes; it is therefore not recommended for general-purpose barcodes with 4 or more characters.

Verify

The value entered for this parameter determines the number of correct additional decodes required after the

initial decode, prior to a barcode being accepted. Higher values significantly increase the time it takes to

decode a barcode but also improve the reliability of the decoded barcode.

Security

This parameter controls the tolerance for decoding edge-to-edge barcodes (Code 93, Code 128, UPC/EAN).

Lower values have a lower tolerance for misreads, but they also increase the time it takes to decode the

barcode. The default value of 30 is generally a good compromise setting.

The barcode symbologies for the scanner are listed in the following table.
