3.1.1 USB HID key board

Keyboard layout
You can use it to change your keyboard layout,
so your scanner can scan bar codes of different
languages. Remember, you also need to change
your input method.

Function key
It maps function keys to ASCII codes, so you can
scan bar codes in place of the function key input.
For example, if you scan the numeric bar code “1”
and then “2,” your scanner sends the specific
character to your computer as though you press
F2. The code mapping range is from 01 to 1F.
For more information about ASCII codes, see
ASCII table in Appendix B .

Numeric key
The keypad is located to the rightmost of a
keyboard. You need to select this mode if your
program only accepts numerals. When selecting
Alt+Keypad, your bar code data will be sent as if
you’re pressing “Alt+number.” It is useful when
your bar code contains a special character, such
as the Euro sign (€).

Caps lock
It determines whether the state of the Caps Lock
key affects the output of bar codes.

Inter-character delay
It determines how fast your computer receives
each character and displays it on the screen. If
the speed is set too fast and your computer
system is slow, your computer may lose data.
