Ignore Unknown Characters
Unknown 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 on
the linear imager scanner. When Do Not Send Bar Codes With Unknown Characters is selected, bar code
data is sent up to the first unknown character, then the linear imager scanner issues an error beep.

This is the delay in milliseconds between emulated keystrokes. Scan a bar code below to increase the delay
when hosts require a slower transmission of data.
