Ctrl Char Mapping
Ctrl Char Mapping
The Ctrl Char Mapping button activates a dialog to define the operations the Data Collection 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.
Ctrl Char Mapping
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.
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.
