Chapter 2: Braille Display Mode
2.1 Introduction to Braille Display Mode.
VarioUltra is a very smart braille display. Unlike other braille devices that
limit you to one single connection via Bluetooth or USB, VarioUltra lets
you connect simultaneously with up to 5 different devices. VarioUltra
was the first braille device in the world to offer multiple device
connectivity.
Connecting VarioUltra and up to 5 different devices is possible using 1 x
USB and 4 x channels of Bluetooth. Once paired and/or connected, you
can switch instantly between devices by pressing and holding down S2,
and then tapping a corresponding braille key that is assigned to the
device in question. This command instructs the braille display to show
information from the chosen device.
** New ** with v1.4: this command can now wake up a paired iOS or
Android device, so long as it is in standby mode, and in range of
your VarioUltra.
For example:
1) S2 plus B1 selects the USB device
2) S2 plus B4 selects Bluetooth channel 1 (bt1)
3) S2 plus B5 selects Bluetooth channel 2 (bt2)
4) S2 plus B6 selects Bluetooth channel 3 (bt3)
5) S2 plus B8 selects Bluetooth channel 4 (bt4)
When toggling between channels, remember to release all buttons after
entering a command. If you don’t let go of S2 between selections, it’s
likely that nothing will happen.
Additional Commands in Braille Display Mode:
1. S2+B9 (left thumb key): presents a hint message with battery
status, time and date. Press the routing button above the first cell
to freeze the message. Press any other routing key to clear the
message.
2. S2+B2 switches off Bluetooth.
3. S2+B3 opens a list and presents which device is paired and
connected to the available Bluetooth channels. Move left and right
to get the information.
a. VarioUltra presents the channel and the name of the device.
