Barcode - Ctrl Char MappingBarcode - Ctrl Char MappingThe Ctrl Char Mapping button (Control Character Mapping) activates a dialog to define the operations the LXE Wedge performson control characters (values less than 0x20) embedded in barcodes. Control characters can be replaced with user-defined textwhich 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 AllWhen Translate All is checked, unprintable ASCII characters (characters below 20H) in scanned barcodes are assigned totheir 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 keystrokesare simulated.ParametersTranslate AllThis 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 barcode are translated to theirequivalent 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.CharacterThis is a drop down combo box that contains the control character name. Refer to the Character drop down box for the list ofcontrol 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 theReplacement edit control. Ignore (drop) is highlighted so the user can type a replacement if the control character is not to beignored.Once the user types any character into the Replacement edit control, reselecting the character from the Character drop downbox redisplays the default Ignore (drop) in the Replacement edit control.E-EQ-HX2RG-M [ 154 ] HX2 Reference Guide
