FN1 Substitution Values
Key Category Parameter # 103
Decimal Value Parameter # 109
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, 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 in Appendix G, Numeric Bar Codes.
To correct an error or change the selection, scan Cancel on page G-2.
See USB Keyboard FN 1 Substitution on page 6-12 to enable FN1 substitution for the USB HID keyboard.
