5.5 Firmware updates
So that you can prepare yourself for the future and always acquire the latest VarioPro
developments, it is now possible to update the Braille display’s software. All you have
to do is to connect the Braille display to the PC and the update program will
automatically bring the display up-to-date. This program is so designed that the
Braille display can still be used and a new update attempted should an update fail.
The update can be launched with both USB and serial connections.
During a software update the Braille display beeps every second and a status bar
appears on the Braille cells.
