APPENDIX I ASCII CHARACTER
SETS
NOTE For the Keyboard Wedge Interface, Code 39 Full ASCII interprets the bar code special character ($ + % /)
preceding a Code 39 character and assigns an ASCII character value to the pair. For example, if you
enable Code 39 Full ASCII and scan +B, it transmits as b, %J as ?, and %V as @.
Scanning ABC%I outputs the keystroke equivalent of ABC >.
