USB Ignore Unknown Characters

This option applies only to the HID Keyboard Emulation device and IBM device. 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. When Do Not Send Bar Codes With
Unknown Characters is selected, for IBM devices, bar codes containing at least one unknown character are not
sent to the host, and an error beep sounds. For HID Keyboard Emulation devices, the bar code characters up to
the unknown character are sent, and an error beep sounds.

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”. This allows support for other country variants.
