on the PC, select Settings > Control Panel > System; on the "Hardware tab, select "Device
Manager" and look through the list of ports.
Bluetooth Interface
Bluetooth is a wireless connection. Similar to USB, Bluetooth simulates a virtual COM port.
Wireless technology, along with the Braille Trail Reader's long battery life, provides total freedom
and independence from wires within the range of a Bluetooth connection (range is approximately
30 feet). Bluetooth is now a common interface for mobile phones, PDAs and Notebook PCs. PCs
can be upgraded with Bluetooth using a Bluetooth USB dongle, which automatically installs itself
on Windows 7, Windows 8, Windows 10 (and above) when plugged in.
When two Bluetooth devices are connected for the frst time, they have to be "paired". This is for
security reasons. Later, the devices will recognize each other automatically, if allowed by the user.
In the Bluetooth environment of a PC, you will fnd Braille Trail Reader LE as:
Brailliant BI 14 6500141XXXXX (where XXXXX is the serial number of your unit.)
Connecting to a PC or Notebook (in Terminal Mode)
Your Braille Trail Reader can be used as a braille display with popular PC screen readers such
as JAWS, Supernova, and others. The PC or Notebook must provide either USB or a wireless
Bluetooth interface (built-in or by using a USB Bluetooth dongle). We recommend Windows 7,
Windows 8 or Windows 10 for Bluetooth.
To fnd out which virtual serial port is provided by a Bluetooth or USB interface in Windows:
1. Open the Control Panel (Start/Settings/Control Panel).
2. Select "System" from the list.
3. In the window now opening, select the tab "Hardware".
4. On this tab, click on "Device Manager".
5. In the Device Manager's tree view, open the branch "Ports (COM and LPT)".
6. Search for something similar to "standard serial over Bluetooth port (COM 13)". There may
be more of these. Take note of the number after the COM.
7. This number is the number of the virtual COM port the device is connected to. The screen
reader wants to know this port.
On Bluetooth, you will see two ports - one outgoing and one incoming. The outgoing port is the
one we want to use to connect. When connected using Bluetooth, the serial port used by your
device may also be found in the Properties of your connected device in the Bluetooth Manager.
Some screen readers do not support higher values of COM Ports. In that case, you may want
to change the port number. Do this by selecting the "Port (COM and LPT)" branch in Device
Manager as described above, and right-click on the Port you want to change (Shift F10 will do
the same). The context menu opens and you can click on "Properties". Then click on the tab
"Port settings", and click on the "Advanced" button. In the window now opening is a List Box
"COM Port Number", where you can choose a free port number. Numbers not available will be
marked.
