*FP* Braille configuration
Braille configuration. This menu item is only available when using an ALVA BC640
with Feature Pack. Press the Smartpad Enter key to open the Braille configuration
submenu. The Braille configuration submenu contains three menu items: keyboard
layout, Braille table and contracted (Grade 2) table. These three items are being used
to translate the Braille input on the 8-key Braille keyboard into text. It is therefore
important to select the same keyboard layout on the ALVA BC640 as in Windows.
Your Windows keyboard layout can be found in the Windows Control Panel/ Regional
and Language options/ Languages/ Details. When a keyboard layout is selected, the
ALVA BC640 will attempt to match the Braille table and contracted table if present. If
there is no matching Braille table present, no changes will be made. Or, you can
manually select a different Braille table or Contracted table. The default Braille table
is the NABCC (North American Braille Character Code) and the US English
contracted table. The selected Braille table is used in the Local Menu. Please note
that screen readers have their own Braille tables. Therefore, the Braille that is being
displayed on the Braille display cannot be controlled by the ALVA BC640. Selecting a
different Braille table for displaying Braille should be done in the screen reader itself.
To enable or disable the contracted (or Grade 2) Braille input, press Space + B1245
(Braille keys 1, 2, 4, 5). The ALVA BC640 will generate a serie of beeps to indicate
that the contracted Braille is turned on or off. Space + B234 will enable or disable the
special character set for languages that require multi-lingual input. When the Arabic
Braille input is selected, this key combination will toggle between English and Arabic
input.
Pressing Smartpad 1 allows you to exit this submenu.
Dot pressure: 5
Dot pressure. Select the Braille reading comfort by setting the dot pressure. If you
prefer hard and stiff Braille dots set the value to 5. If you prefer soft and weak Braille
dots, set the value to 1. The default setting is 5.
Number status cells: 0
Number status cells. By default the number of status cells is 0. To enable status
cells, select a value of 1 to 20 status cells when using an ALVA BC640 or a value of
1 to 40 when using an ALVA BC680. If the statuscells are set to 0, the statuscells will
be disabled and all 40 or 80 Braille cells are used for displaying text and data. Status
cells provide useful information about the text on the screen, Windows controls and
screen reader mode.
