1.10 Updating VarioUltra.
From time to time, new VarioUltra software updates will become available for download from our web site at
http://www.baumusa.com/support/varioultra.html
If you own a VarioUltra that is running software version 1.0, please contact BAUM USA technical support for
assistance with updating to newer software versions.
If your VarioUltra is running software version 1.1 or newer, the instructions to update are as follows:
1. Download the update zip file and copy it to the root of the VarioUltra Flashdisk.
2. Make sure that your VarioUltra is connected to a power source.
3. Start the upgrade by simultaneously pressing braille keys B7+B8, and display buttons D3+D6.
4. Once the update is complete, VarioUltra will restart automatically.
The VarioUltra update process allows the installation of different components which are part of the update
package. The routine checks which components are already present on the device, and installs only those items
that are new. Different progress bars will appear on the braille display during installation steps. Installation typically
takes less than 2 minutes.

Chapter 2: Braille Display Mode.
2.1
Introduction to Braille Display Mode.
A major benefit of VarioUltra is the unique ability to connect simultaneously with multiple devices. The device
contains 5 connections in total: 1 USB and 4 Bluetooth. Once paired and 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.
For example:
System key S2 plus braille key B1 selects the USB device
System key S2 plus braille key B4 selects Bluetooth channel 1
System key S2 plus braille key B5 selects Bluetooth channel 2
System key S2 plus braille key B6 selects Bluetooth channel 3
System key S2 plus braille key B8 selects Bluetooth channel 4
The following sections provide detailed instruction on how to connect to devices via USB and Bluetooth. For
Bluetooth connectivity, please read section 2.12 for details on mapping devices to a specific channel.
2.2
Using VarioUltra as a USB Braille Display.
The first thing to do is confirm that the Device Mode switch is facing toward the front of VarioUltra.
With Device Mode set to braille display, insert the micro USB cable into the micro USB port on VarioUltra,
remembering that the wider edge of the connector needs to be on top. Connect the other end of the USB cable
into the USB port of your computer. Depending upon the screen reader software being used on the computer,
special settings and/or the installation of additional drivers may be required. COBRA 10.1, the screen reader from
BAUM Retec, recognizes VarioUltra automatically as a USB HID Braille display.
in the form of a zip archive file.
