your scanning speed, a longer interblock delay may ensure the data
integrity.
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 be compromised because of the auto tracing. If the scanning
performance is poor (or can not scan) or the scanner can not
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 (CapLock 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.
