Bar Code - Ctrl Char Mapping

The Ctrl Char Mapping button (Control Character Mapping) activates a dialog to define the operations the Wedge performs
on control characters (values less than 0x20) embedded in bar codes. 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.
When Translate All is checked, unprintable ASCII characters (characters below 20H) in scanned bar codes are assigned to
their appropriate CTRL code sequence when the bar codes are sent in Character mode.
The wedge provides a one-to-one mapping of control characters to their equivalent control+character sequence of key-
strokes. If control characters are translated, the translation is performed on the bar code data, prefix, and suffix before the
keystrokes are simulated.

Translate All

This option is grayed unless the user has Send Key Messages (WEDGE) on the Main tab selected.
In Key Message mode, when this option is enabled, control characters embedded in a scanned bar code 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 to be 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.

Replacement

The edit control where the user types the characters to be assigned as the replacement of the control character.
Replacements for a control character are assigned by selecting the appropriate character from the Character drop
down box, typing the replacement in the Replacement edit control (according to the formats defined above) and then
clicking the Assign button. The assigned replacement is then added to the list box above the Assign button.
For example, if Carriage Return is replaced by Line Feed (by specifying ^J or 0x0A) in the configuration, the value 0x0d
received in any scanned bar code (or defined in the prefix or suffix) will be replaced with the value 0x0a.
The Wedge then sends Ctrl+J to the receiving application, rather than Ctrl+M.
