Using both the serial and USB connections
The ALVA Satellite can be connected with either the serial or USB
connection to the PC, or with the USB connection to one PC and the
serial connection to a second PC. The ALVA Satellite will
automatically use the connection that is used for communication at
that moment. For example, if the Braille display detects serial
communication in a DOS environment, the serial connection will be
automatically selected.
However, if both serial and USB communication is set up (for
example when both PCs send data to the Braille display) the ALVA
570 Satellite Pro will select the USB connection as the main
communication channel. If you want to change to the serial
connection you can specify the change by pressing the Touch Cursor
above
ser
in the main Local mode menu.
