Barcode – Ctrl Char Mapping
See Also: Barcode Processing Overview earlier in this chapter.
The Ctrl Char Mapping button activates a dialog to define the operations the LXE Wedge
performs on control characters (values less than 0x20) embedded in barcodes. Control characters
can be replaced with user-defined text which can include hat encoded or hex encoded values. In
key message mode, control characters can also be translated to their control code equivalent key
sequences.

Translate All
When Translate All is checked, unprintable ASCII characters (characters below 20H) in scanned
barcodes are assigned to their appropriate CTRL code sequence when the barcodes are sent in
Character mode.
The wedge provides a one-to-one mapping of control characters to their equivalent
‘character sequence’ of keystrokes. If control characters are translated, the translation is
performed on the barcode data, prefix, and suffix before the keystrokes are simulated.
Translate All This option is grayed unless the user has Key Message mode (on the Main tab)
selected. In Key Message mode, when this option is enabled, control characters
embedded in a scanned barcode are translated to their equivalent ‘control’ key
keystroke sequence (13 [0x0d] is translated to M keystrokes as if the
user pressed the CTRL, SHIFT, and m keys on the keypad Additionally, when
Translate All is disabled, any control code which has a keystroke equivalent
(enter, tab, escape, backspace, etc.) is output as a keystroke. Any control code
without a keystroke equivalent is dropped.
