The Focus 44, 70, and 84 refreshable Braille displays provide a tactile interface to your computer. Used together with screen access software such as JAWS for Windows versions 4.02 and later, the Focus displays enhance your computing experience.
The Focus Braille displays include the following features:
The Focus Braille displays ship with the following items:
The Focus displays are designed with the Braille cells near the back of the unit so they are as close as possible to the keyboard. There is a cursor routing key above each Braille cell. There are two advance bars and two General Display Buttons (GDB) between the Braille cells and the back of each unit.
Between the Braille cells and the front of each unit, there are eight keys similar to those on a Perkins style Braille keyboard. These keys are used to enter commands. To either side of these keys, at either end of the display, there are Whiz Wheels used for easy navigation. Along the front edge of the display are three buttons, LEFT SHIFT, SPACEBAR, and RIGHT SHIFT. These three keys are used together with the Braille keys when entering commands.
On the left end of the display, there is a nine pin serial port, AC adapter jack, and a USB port. The AC adapter is required when connecting the Focus display to your computer via the serial port, but is not needed with a USB connection.
On the right end of the display, there are four audio jacks: the two near the front are audio out jacks, and the two near the back are audio in jacks. The audio out jacks are further designated with the front jack marked as speaker and the other marked as headphones. On this side, there is also another USB port.
Note: You can only use one USB port at a time. The second USB port does not function as a pass through port.
The Focus Braille displays can be connected to your PC using either the USB port or the nine pin serial port. When using a USB connection, the Focus Braille display is powered from the PC through the USB cable. When using a serial port connection, you must also attach the AC adapter.
Note: Not all USB ports provide enough power to run the Focus Braille displays. If your USB connection does not provide sufficient power, the Focus display will beep every five seconds. This occurs most frequently with non-powered USB hubs and smaller portable computers.
The Focus Braille display has two USB ports, one on either end of the display. Both ports are present for convenience in connecting the display. The second USB port cannot be used as a USB hub for another device.
When using the USB connection, we recommend you do not connect the AC adapter unless your USB connection does not provide sufficient power. If you are using the AC adapter with a USB connection, disconnect the AC adapter before switching the USB connection from one end of the Focus to the other.
The adjustable keyboard accessory is used to position and angle your keyboard or portable computer for ease of use with the Focus Braille display. The keyboard accessory is part of the Focus Braille display's handle. Flip the back edge of the handle down away from the display. (This would be the top if you are holding the Focus up by the handle.) Pull out the legs and position the feet. The legs and feet are adjustable to provide you the support you need and angle you desire for your keyboard or portable computer.
Tip: The button on the left edge of the keyboard accessory functions as a lever that releases the catch that holds the Keyboard Accessory in place. It does not take much pressure to release this catch, but that pressure must be upward pressure, not inward pressure as you might expect with a button.
The following sections discuss use of the Focus 44, 70, and 84 refreshable Braille displays with JAWS 4.02 and 4.5 for Windows.
JAWS support for the Focus Braille displays can be added when JAWS is first installed, or after JAWS is installed.
To add support for the Focus displays during JAWS 4.02 installation, select either the Guided or Advanced setup option. On the Select Braille Components page, or on the Select Components page of setup, check the "Focus 44, 70, or 84" item. On the Set Options for the Focus Braille Display page, select the Com port or the USB port to which the Focus display is attached. On all other pages of setup, select the options you need and/or desire. With JAWS 4.5, your Focus display is ready to use once the setup is complete. If you are installing JAWS 4.02, you will need to update the Focus driver. For more information, please see “Updating the JAWS 4.02 Focus Driver.”
To add support for a Focus display after JAWS 4.02 is already installed:
Once setup has installed support for the Focus display, JAWS is restarted and you are ready to use your Focus Braille display. If you currently have JAWS 4.02.52, please proceed with the instructions below to update to the newer driver. If you currently have a version of JAWS later than 4.02.52, you do not need to update the Focus driver.
This section describes the method behind the command assignments for JAWS and the Focus Braille displays. Once you understand this methodology, there is no need to memorize a long list of commands. The commands are separated into Convenience commands, JAWS commands, Windows commands, and Braille commands. There is only one assignment pattern for each. Focus commands are consistently based on JAWS and Windows commands. If you are familiar with JAWS and Windows keyboard commands, Focus commands are very easy to learn. If you become familiar with Focus commands, JAWS and Windows keyboard commands are also easy to learn.
These commands are the most common functions and are performed right from the Braille display. They do not require any chording or use of the SHIFT keys.
These commands are easy to learn if you are familiar with JAWS. And if you are just beginning to learn your Focus display and JAWS, these commands should help you learn JAWS keyboard commands as well.
The RIGHT SHIFT key on your Focus display corresponds to your INSERT key on the keyboard. The JAWS keyboard command to make the JAWS window active is INSERT+J, so the corresponding Focus command is RIGHT SHIFT+J (RIGHT SHIFT+DOTS 2-4-5).
Many JAWS keyboard commands use INSERT together with the function keys, F1 through F12. For keyboard commands that use INSERT+F1 through F9, just press and hold down the RIGHT SHIFT on the Focus and press the computer Braille number of the function key. For example, the JAWS keyboard command for screen sensitive help is INSERT+F1, so the Focus command is RIGHT SHIFT+1 (RIGHT SHIFT+DOT 2).
Windows commands follow a similar convention. Many Windows commands use CTRL, ALT, or SHIFT as part of the command. On the Focus, the LEFT SHIFT key is used in these commands. The Windows keyboard command to copy selected text to the clipboard is CTRL+C, so the Focus command is LEFT SHIFT+C (LEFT SHIFT+DOTS 1-4).
The same letter assignments that are used with Windows commands are used for the equivalent Focus commands to make it as easy as possible to learn to use the Focus displays or to learn Windows.
These commands primarily change settings for your Braille display. They are key combinations with the SPACEBAR, referred to as chord commands. Use the SPACEBAR like other modifiers (SHIFT, CTRL, ALT, etc.). Press SPACEBAR first, hold it down, and then press the other key or keys that are part of the command. These commands all change the settings used to format, translate, or present information on your display.
The computer Braille number and function key relationship does not apply to the List System Tray Icons command, INSERT+F11 on the keyboard. We have assigned RIGHT SHIFT+K (RIGHT SHIFT+DOTS 1-3) to this command.
The command to open the Window List dialog, INSERT+F10, is RIGHT SHIFT+0 (RIGHT SHIFT+DOTS 3-5-6).
Commands that have been assigned using the Convenience Commands convention are not duplicated using the JAWS/Windows assignment convention.
There are other exceptions based on availability of keys, however we have attempted to retain the logic of consistency with the JAWS or Windows commands wherever possible.
All convenience commands use only the Braille keys. These commands do not use the SHIFT keys or SPACEBAR.
Note: For your convenience, we have provided both the Braille signs for each command and the dot pattern equivalents. If there is no Braille sign corresponding to the dot patterns, the dot patterns are listed in both columns.

To select with the cursor routing keys, press and hold down LEFT SHIFT, then press the cursor routing key above the text where you wish to begin the selection. Release both keys. Move to where you wish to end the selection, and press LEFT SHIFT plus the cursor routing key at that location. Use any navigation commands to move from the begin point to the end point of the text you are selecting, even the Whiz Wheels, but if the window containing the text scrolls, this affects what information is selected.
All JAWS commands use the RIGHT SHIFT key as part of the command.
Note: For your convenience, we have provided both the Braille signs for each command and the dot pattern equivalents. If there is no Braille sign corresponding to the dot patterns, the dot patterns are listed in both columns. Use computer Braille for numbers noted in the Braille Sign column.

The Focus Braille displays provide two Whiz Wheels, two advance bars, and cursor routing keys above each Braille cell. There are also two General Display Buttons between the advance bars.
The Focus Whiz wheels are used to quickly move through files, dialogs, lists, and menus. In a file, move by line, sentence, or paragraph. In a dialog, move between the available controls, and even interact with them. In a menu, move up and down through the menu items.
The Focus advance bars are used to move forward or back through a file or while in line mode. Press the Left Advance bar to move left on a line or back through a document. Press the Right Advance bar to move right on a line or forward through a document.
The Focus displays provide cursor routing keys above each Braille cell. Press a cursor routing key to move the cursor to that point, or to select a link in a web page or email message. In line mode, press a cursor routing key to open a menu or select menu items.
Press the RIGHT General Display Button with a cursor routing key to simulate a right mouse click at that location.
The Focus Braille displays provide several features that you can customize to suit your needs. You can adjust the location of the status cells, vary the firmness of the Braille dots, and enable a Rapid Reading mode.
These settings are all adjusted under Configuration Manager, Set Options, Braille Options, Focus Braille Display Options. Open Default.jcf to adjust these settings for all applications, or open an application specific .jcf file to adjust these settings for that application. For more information, refer to JAWS Configuration Manager help.
Specify if the informational Status Cells are located on the left or right end of the display, or choose to not display them at all. The status cells are located at the left end of the display by default.
Specify the start and end cell for display of information. Use the Reading Line edit spin boxes to only display information within the portion of the display you wish to use. The default settings are determined by the location of the Status Cells, and the length of the display.
Specify the firmness of the Braille dots on the Focus display. There are five levels of firmness. Adjust the display to the level of firmness most suited to the sensitivity of your fingers.
Set the Focus display to use only 20 Braille cells. Limiting the Braille display to 20 cells may increase your reading speed. When the Rapid Reading check box is checked in the Focus Braille Options dialog, the Placement of Status Cells radio buttons and Reading Line edit spin boxes are disabled.

The Focus Braille displays have built in diagnostic tests for the routing keys, Braille display, Whiz Wheels, Braille keys, advance bars, and General Display Buttons.
Before entering diagnostics mode, disconnect the Focus from your computer and unplug the AC adapter. To perform these diagnostic tests, you only need the Focus refreshable Braille display and the AC Adapter.
Attach the AC Adapter to the Focus. The Focus displays the focus model number followed by the firmware version.
Press LEFT SHIFT+SPACEBAR+RIGHT SHIFT. The Focus displays “diag” after the firmware version.
The routing key test ensures that each of the routing keys and the Braille display work properly. Enter the routing key test by pressing dots 1 4 on the Braille keyboard. The Focus displays “cursor test e to end” when the Focus is ready to start the test. The pins on the Braille display cell are raised when the cursor routing key above that cell is pressed. Press each of the cursor routing keys and verify that the appropriate Braille cell is activated. Press Dots 1-5 (E) to exit the routing key test and return to the other diagnostic functions.
The display test is used to ensure that each pin on the Braille display can be activated. The display test also allows you to clean the Braille display. Press Dots 1-4-5 (D) to enter the display test. The Braille display toggles all the pins up and down for approximately 20 seconds. The display test automatically returns to the other diagnostic functions at the end of the test. The Display test returns the display to the "diag" message when complete.
The key test ensures that each of the keys and Whiz Wheels work properly. Press Dots 1-3 (K) to enter the key test. The Focus displays “key test press key” when the Focus is ready to start the test. The Braille display shows each key that is pressed. Refer to the table below for the exact dot position for each of the keys. Press each of the keys and verify that the appropriate Braille data is displayed. To exit the key test, disconnect the AC adapter.
