1Introduction
The ALVA Satellite Braille display presents text, graphic and other
information in Braille corresponding to what is displayed on a
computer screen. Used together with screen reader software the
Satellite display can be installed for a particular operating system
such as Windows 98 or Windows NT to provide a tactile and audible
user interface.
The ALVA 570 Satellite Pro Braille display offers an enhanced
ergonomic design that extends the navigation and operation
possibilities of the screen reader software. The features of the ALVA
570 Satellite Pro are designed for optimal capabilities when working
in a graphical computer environment. Note that the functionality of
the ALVA 570 Satellite Pro depends somewhat on the Braille display
options that your screen reader software offers.
The Satellite Braille display was designed following the Open
Standard philosophy. This enables compatibility with most screen
reader software and operating systems. Contact your distributor or
Optelec for updated information about screen reader software that
fully supports the functionality and possibilities of the ALVA 570
Satellite Pro Braille display or tailor-made solutions.
ALVA Satellite Braille displays are optimized to work in a graphical
computer environment. It is also possible to work in a non-graphical
environment under MS-DOS.

2.1 Surface and front panel layout
The ALVA 570 Satellite Pro Braille display is designed with a row of
70 Braille cells at the front of the flat surface. Behind the Braille
cells, a flat surface is provided so that a keyboard can be placed on
top of the Braille display. Above the row of Braille cells are two rows
of small buttons known as Touch Cursors (lower row) and Double
Touch Cursors (upper row). Each Braille cell has a corresponding
Touch Cursor and Double Touch Cursor button.
On the left and right side, just below the array of Braille cells, are
two groups of six keys. These groups are called the Satellite
keypads. Each Satellite keypad forms an inner circle of four keys
with two larger keys positioned alongside the circle. At the front of
the Braille display are ten front panel keys: two round keys, one on
the left and one on the right, four rectangular keys in the middle,
and aside two tumbler keys.
2.2 Back panel layout
At the back of the Braille display are the power switch and
connections for the PC, other devices and the power supply. The
connections are partially covered by the case, which extends
somewhat beyond the back panel. Tactile markings have been
placed on the underside of the cover that indicate the meaning of
the connections.
