FN1 Substitution Values
Key Category Parameter # 103 (SSI # 67h)
Decimal Value Parameter # 109 (SSI # 6Dh)
The Wedge and USB HID Keyboard hosts support a FN1 Substitution feature. When enabled any FN1
character (0x1b) in an EAN128 bar code is substituted 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 currently installed host interface for the
desired value.
To select a FN1 substitution value via bar code menus:
1. Scan the bar code below.
2. Look up the keystroke desired for FN1 Substitution in the ASCII Character Set table for the currently
installed host interface. 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.
