USB Ignore Unknown Characters
This option applies only to the HID Keyboard Emulation device and IBM device. Un-
known characters are characters the host does not recognize. When Send Bar Codes With 
Unknown Characters is selected, all bar code data is sent except for unknown characters, 
and no error beeps sound. When Do Not Send Bar Codes With Unknown Characters is 
selected, bar code data is sent up to the first unknown character, then the scanner issues 
an error beep.
Emulate Keypad
When enabled, all characters are sent as ASCII sequences over the numeric keypad. For 
example ASCII A would be sent as “ALT make” 0 6 5 “ALT Break.”
