Non-Decoded Scanners
Options
All the available bar code symbologies for this type of scanner can be selected in this tab.
A ‘plus’ sign (+) to the left of the menu item indicates that a sub-menu of parameters is
attached.
•
Tap on the + sign to display the sub-menu.
•
To change a parameter value, double-tap on the parameter. If you need to type a value, a
dialog box is displayed in which you can type a new value. If you need to change a yes
or no value, double-tapping on the parameter toggles between yes and no.
If you’re using the keyboard:
•
Highlight the bar code 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.

to display these parameters.
Dot Time (msec)
The value selected for “Dot Time (msec)” determines (in milliseconds) how long the target-
ing 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 bar codes (2 characters).
When disabled, these short bar codes are rejected.
Enabling “Short Code” may reduce the robustness of the decoding since the hand-held must
decode more potential bar codes; it is therefore not recommended for general-purpose bar
codes with 4 or more characters.
Verify
The value entered for this parameter determines the number of correct additional decodes re-
quired after the initial decode, prior to a bar code being accepted. Higher values significantly
increase the time it takes to decode a bar code but also improve the reliability of the decoded
bar code.
