Function

Code

The scanner can emulate function and other special keys on the keyboard by

scanning some pre-defined labels. Appendix B includes those labels for

special keys on PC, Macintosh, and IBM terminals. As an option, you may also

print these labels by printing their corresponding Code 39 characters (in

brackets) to work with scanner.

Caps

Lock

This parameter tells the scanner the current Caps-Lock status of the keyboard

so that the character transmitted by the scanner is in correct case.

　 Auto Trace (For PC AT/XT only):

In Auto Trace mode, the scanner will keep track of the Caps-Lock status

automatically. For some PCs, the scanning performance may he

compromised because of the auto tracing. If the scanning performance is

poor (or can not scan), or the scanner cannot output the upper/lower case

characters correctly, try to select one of the next two choices instead of

auto tracing.

　 Lower Case:

When the keyboard is in the unshifted state (Cap Lock is not pressed),

select "Lower Case".

　 Upper Case:

When keyboard has the CapLock key on, select "Upper Case".

Alt Key Mode

"ALT Key Mode" is a choice in the language selection. Sending characters by

ALT key plus keys on the numeric keypad is a feature in MS-DOS. When

selecting "ALT Key Mode", the scanner sends out the native ASCII

combination codes to represent each character of the bar code scanned. If

your system accepts ALT key sending, you can enable this mode and ignore

selections of the "Upper/Lower Case" and "Language".

You may find these settings on the Appendix D page D2 and D3.
