The wedge and USB HID keyboard hosts support a FN1 Substitution feature. 
Enabling this substitutes any FN1 character (0x1b) in an EAN128 bar code with a 
value. This value defaults to 7013 (Enter key). 
When using host commands to set the FN1 substitution value, set the key category 
parameter to 1, and then set the 3-digit keystroke value. See the ASCII character 
set table for the current host interface for the desired value. 
To select a FN1 substitution value via bar code menus: 
1.  Scan the bar code below. 
 
2.  Locate the keystroke desired for FN1 substitution in the ASCII character set 
table in the appropriate host interface chapter. Enter the 4-digit ASCII value by 
scanning each digit. 
To correct an error or change the selection, scan Cancel.
