FN1 Substitution Values
The Wedge and USB HID Keyboard hosts support an 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).
To select an 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 Value - Code 39 Encode - Keystroke on page
E-1 for the currently installed host interface.
3. Enter the 4-digit substitution value by scanning each digit in Appendix D, Numeric Bar Codes.
To correct an error or change the selection, scan Cancel.
To enable FN1 substitution for keyboard wedge, scan the Enable FN1 Substitution bar code on page 5-10.
To enable FN1 Substitution for USB HID keyboard, scan the Enable FN1 Substitution bar code on page 7-9.
Transmit “No Read” Message
Scan a bar code below to select whether or not to transmit a No Read message. When enabled, the characters NR
are transmitted when a bar code is not decoded. When disabled, if a symbol does not decode, nothing is sent to
the host.
