Connecting the Focus
You can connect the Focus braille display to your computer using either the
USB port or Bluetooth. If you connect using USB, the display is powered from
the computer through the USB connection cable. This also charges the internal
battery.
As soon as you connect the USB cable to the computer, the Focus immediately
turns on. When the USB cable is removed, the Focus turns off. Pressing the
power button while connected to USB causes the focus to display the model,
firmware version, battery status, and the letters US in the last two cells to
indicate it is connected to USB. Pressing a cursor router button returns the
display to normal operation.
Bluetooth is a short-range wireless communications technology. Devices with
Bluetooth capabilities can communicate with each other over a distance of
about 10 meters (30 feet) without requiring a physical connection. Using the
Focus wirelessly over Bluetooth means you do not have any cables to worry
about and you can relax on your couch and use the Focus as both a braille
display and keyboard to access your computer from across the room.
In order to use Bluetooth, you must establish a partnership with a Bluetooth
enabled computer. The majority of modern notebook computers and mobile
phones as well as some models of desktop computers offer built-in Bluetooth
support. However, not all computers offer this. If your computer does not have
built-in Bluetooth, you will need to purchase an external USB Bluetooth adapter
and install the appropriate drivers on your system to enable this functionality.
Refer to the documentation that came with your Bluetooth hardware to ensure
Bluetooth is properly configured on your computer.
