kb parameter - keyboard type
the following bar codes are used to define the type of keyboard in use. if necessary, scan the appropriate bar code.
kb parameter - keyboard type
the following bar codes are used to define the keyboard country type. if necessary, scan the appropriate bar code.
kb parameter - caps lock mode
when caps lock is used on the keyboard, choose enable caps
lock. once enabled, the scanner will simulate caps
lock keyboard input. this mode will not work with all keyboard types.
to detect automatically if caps lock is used, enable auto-detection caps lock mode. this will only work with an at computer.
kb parameter - alt mode
when this option is enabled, the scanner will duplicate this keyboard sequence: hold down the alt key; type the decimal number that corresponds to the appropriate keyboard character. caution should be observed when using alt mode because a scanner to host application conflict may occur if the host software application uses the alt key as a "hot" key.
kb parameter - inter scan code delay (at and ps/2 modes)
the time specified with an interscan code delay bar code represents the amount of time between individual 9 bit scan codes. each character of a bar code takes between two and twelve of these scan codes to be passed through to the pc via the keyboard interface. this parameter may need to be adjusted for operation with certain pc keyboard bios's. network operating systems often use microprocessor time slices to service network information requests instead of the keyboard interface. while not an issue with manually entered keystrokes, this timing can be critical with automatic scanner data entry. interscan code delays can be a useful system tuning tool in these environments.
kb parameter - xt - clean-up bit
some keyboard bios's require a "cleanup bit" to be transmitted before an actual scan code being clocked over to the motherboard. enabling this feature will cause the scanner to send this extra bit to the host computer. more commonly found on older xt style bios's, and some at bios's. (required by some nec 80286 machines).
