Non-Decoded Scanners
146 Psion Teklogix 7530 G2 Hand-Held Computer User Manual
A ‘plus’ sign (+) to the left of the menu item indicates that a sub-menu of parameters
is attached.
• Tap the stylus 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.
5.11.2.1 Non-Decoded Options
• Tap the stylus 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 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 required 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.
