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.

See “Hat Encoding” and “Decimal-Hexadecimal Chart” at the end of Appendix B “Technical
Specifications”.
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
control+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 Control+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.
Character This is a drop down combo box that contains the control character name. Refer
to the Character drop down box for the list of control characters and their
names. When a character name is selected from the drop down box, the default
text Ignore (drop) is shown and highlighted in the Replacement edit control.
Ignore (drop) is highlighted so the user can type a replacement if the control
character is not being ignored. Once the user types any character into the
Replacement edit control, reselecting the character from the Character drop
down box redisplays the default Ignore (drop) in the Replacement edit control.
