About This Guide

This guide represents the complete user documentation for Refreshabraille 18. It is complete and accurate at the date of writing. Additional information may be made available as programs evolve and are created. For the latest version of this documentation and any additional information, see the Refreshabraille 18 website at tech.aph.org/rbd_info.htm.

The purpose of this guide is to help the user connect the Refreshabraille 18 with the mobile device of their choice, install any needed communication and display drivers, and configure the software running on that device. In most cases, the screen reader will provide the most current information about the specific commands supported for that software.

The writers of this documentation presuppose the user to have some familiarity with the operating system and the software for the chosen device. The guide does not provide a tutorial on how to perform each step for each device or operating system. Instead, it provides general guidelines. For example, the guide may direct the user to open the main menu on a Symbian smartphone. Given that the keys are in different locations for different phones, it is not practical to describe every phone and its key layout. In another example, the guide provides instructions about accessing the Control Panel or the System Tray for Windows. The writers of this guide presume the user knows the various ways to get to the Control Panel in the version of Windows being used. The guide does not attempt to instruct the user in all the ways to successfully use Windows with keyboard commands.

Note: For the purposes of this guide, the braille dot numbers are used when referencing key combinations (dots 1-8); and where applicable, the corresponding braille letter, letter contraction, symbol, whole-word contraction, or Nemeth number is given in parenthesis.

In addition to this documentation, there is a Refreshabraille 18 listserv where users and the development team discuss various aspects of this versatile new display.

To subscribe to the Refreshabraille 18 email list, send a blank email to rbd-subscribe@tech.aph.org. A confirmation email is returned to which you must respond before you may write to the list. A welcome message is sent when your confirmation email is received. Once confirmed, the email address to use to write messages is rbd@tech.aph.org.

The Program and Documentation CD

The CD supplied with Refreshabraille 18 contains documentation and software to help you get started using your new display. If you cannot find your CD, you may download the entire contents from a zip file at tech.aph.org/rbd.zip. Unzip the contents to a flash card or burn to another CD if necessary.

Orientation

To familiarize yourself with the keys and controls on Refreshabraille 18, place it on a flat surface with the braille cells on the side farthest away from you.

Later in this documentation are instructions about how to flip the orientation so the braille cells are closest to you if you prefer this.

Braille Cells

Refreshabraille 18 features 18 eight-dot braille cells. If you are new to refreshable braille displays, you may not be familiar with eight-dot braille. It is similar to six-dot braille with two additional dots below dot 3 and dot 6. These two additional dots are called dot 7 and dot 8, and they are used to indicate capitalization in computer braille (dot 7) or to indicate some attributed text or a cursor. Their exact use depends on the software you use with the display. Check the software documentation for exact usage.

Cursor Routing

The 18 cursor routing keys are located immediately below the braille cells. Each braille cell has its own router key. These keys work in conjunction with the screen reader or portable device to move the editing cursor to the place in the document that corresponds with what appears on the display. This makes it easy to edit a document because you do not need to synchronize the program cursor with the reading location on the display. The cursor routing keys also activate a menu selection or button in many of the supported screen readers.

Power Button

With Refreshabraille 18 on a flat surface and the braille cells at the top of the display, the power button is located in the middle of the edge surface facing you.

Hold the button in for 2 seconds to turn the device on or off. The Refreshabraille 18 vibrates once when turned on and twice when turned off.

Press the power button quickly to wake up Refreshabraille 18 from standby.

Hold the power button in for 10 seconds to reset the device.

When first turned on, the braille characters for APH and the unique serial number should show on the display. However, you may customize the name of your device, which makes it easy to identify a specific Refreshabraille 18 when there are more than one in an office or classroom.

Braille Input Keys

The braille input keys are arranged with the six traditional keys in a straight line (from left to right: dots 3, 2, 1, 4, 5, 6). The ability to flip the Refreshabraille 18 display means you can type in either orientation. (See the Orientation section above.)

The space key (or space bar) resides in its traditional position (bottom row, middle key) below the six-dot keys. The slightly ridged edge makes it more ergonomic and user friendly. Flanking it to the left and right are the keys to produce dot 7 and dot 8. The configuration for these keys are (from left to right) dot 7, space key, dot 8.

The six braille input keys and two computer braille keys are used to type text. Depending on the application, the dot 7 key is often used as a capital letter modifier, much like pressing shift on a keyboard. The dot 8 key is often used as Enter, but check the documentation for the program or device with which you use the display to see how that software defines the action of the key.

Some eight-dot input displays are arranged so you press the dot 7 and dot 8 keys with the pinky fingers. However, the small width of the Refreshabraille 18 makes it necessary to use your thumbs for these two keys.

Advance Bars and Aux Space

The advance bars and aux space bar are located between the braille input keys (dots 1-6) and the braille cell display. The advance bars are on the left and right sides of the unit and the aux space bar is in the middle.

The right advance bar displays the next line of text, and the left advance bar reverses or scrolls back to the previous line of text. This is the default setting. However, you may reverse the direction of the advance bars. In this scenario, the left advance bar displays the next line of text and the right advance bar scrolls back to the previous line of text. The advantage to reversing the advance bars is it allows the user to read with one hand and advance the text with the other. It is also advantageous for users who are left-handed.

The Aux space is used when you have flipped the display orienting the braille cells closest to you, or when using the display in its normal position (with the braille cells away from you) while holding it with your thumbs below the device. Use your index finger to depress the Aux space.

Directional Button

The directional button is located between the braille input keys dot 1 and dot 4. It is a five-position button, and depending on the software you use with the device, these five different positions usually act like the four arrow keys and select.

Press on the edge of the directional button to move in the indicated direction like an arrow key.

Press in the directional button button to make a selection.

The center of the directional button is also how Refreshabraille 18 sends the six-dot display keys found on many Baum displays. Normally, these devices have three small buttons on each side of the braille cell display, and combinations of those buttons make different commands for different programs. They are called the display keys, and software documentation usually refers to them as D1 through D6.

Since Refreshabraille 18 does not have these six buttons, it uses the center of the directional button along with the regular braille input keys to reproduce the display keys on other devices. If your screen reader requires the key combination D5 and D6, you produce that on Refreshabraille 18 by pressing and holding in the directional button while you press the braille input keys for dots 5-6.

USB and Charging Port

The micro B USB port is located in a recessed cavity in the bottom, left corner of the device. (If the display is flipped with the braille cells closest to you, the port is on the top, right corner). The port is in this protected location to help prevent breaking the connector pins in case the display is dropped. The pins you can feel on the end of the cable should face up when inserting it into the USB port.

This connector serves two purposes: 1) It charges the display, and 2) it communicates with a PC or other device to serve as its keyboard and braille screen.

Battery Care and Use

Refreshabraille 18 has a built in rechargeable lithium-ion battery. This battery technology provides one of the best weight to energy ratios available today, does not suffer from the negative 'memory effect' characteristic of other battery technologies, and discharges very slowly when not in use.

Note: Please fully charge the display before its first use.

To charge the display from a PC or other device with a USB host port, follow these steps:

1. Turn on your PC.
2. Plug the (included) USB cable into the PC.
3. Plug the mini B end of the cable into the USB port on the display. Refreshabraille 18 responds: 'Charging...' for a few seconds, and then the braille display goes blank.
4. Tap the power button to check the status. When fully charged, the braille display reads 'Battery Full.'
5. Charge the display for at least 2 to 3 hours from AC power or 8 to 9 hours from a PC USB connection. You cannot overcharge the battery.

Note: To charge the battery with an optional AC adapter that terminates with a mini USB plug, skip steps one and two and plug the battery charger into a wall outlet instead.

Take the opportunity to read the manual while the battery charges for the first time.

Windows PCs ask about installing the drivers for the device. Refreshabraille 18 charges without the drivers, but you may also install them while the battery charges.

When the battery is low, Refreshabraille 18 periodically flashes 'Battery Low' on the braille display. Use this signal to recharge the battery.

When the battery becomes extremely low, Refreshabraille 18 turns off automatically.

The battery is estimated to last for several years of constant use. The battery in Refreshabraille 18 is not user replaceable. It must be returned to APH for replacement.

First Time Use

Refreshabraille 18, like a computer's monitor and keyboard, is a device designed to be used with other equipment. It does not operate by itself. Refreshabraille 18 provides the screen and keyboard for that other device. Therefore, you must connect Refreshabraille 18 to the device you wish use. Whether that device is a cell phone, a PDA, or PC, every effort has been made to make the process simple, reliable, and trouble free. Be aware, however, that the device you plan to use must have software running on it that has the ability to communicate with a braille display. In the case of your PC, that software is the screen reader program like JAWS or Window-Eyes. On the Mac, it is the VoiceOver program that comes with the system. For phones and off-the-shelf PDAs, screen reader software like Mobile Speak or Talks is required. Accessible devices like Icon already have software as of version 2.0 that integrates with the display.

There are four steps to the successful use of Refreshabraille 18 with your device.

1. Connect the display (see below).
2. Install the drivers, if necessary.
3. Tell the screen reader or device which braille display you use.
4. Turn on braille mode for the screen reader or the device.

Installing USB and Serial Drivers

To install the USB drivers on Windows 7 and Windows 8 follow these steps:

1. Insert the CD that came with your device into the CD drive of your computer.
   Note: If you do not have the CD, the necessary files can be found at http://tech.aph.org/rbd.zip. Be sure to make a note of the path you unzip the files to, as you will need that information again later.
2. Right click on the CD and select Open.
3. Locate and double click the file named usb-driver-setup.exe to run it.
4. Select the language from the dialog box (English is the default language) and select OK.
5. Select Next in the USB Driver Setup Wizard.
6. Select Finish when installation is complete.
7. Insert the included USB cable into the Refreshabraille 18 and your PC.

Connect the Display

To connect the Refreshabraille 18 display, you must first decide which interface to use. How you do that depends on the device to which you wish to connect and what interface possibilities that device supports. In most cases, you will choose the Bluetooth wireless method of communicating between the two devices. This is especially true if you want to use Refreshabraille 18 with a mobile phone or PDA running a screen reader, or other accessible portable devices.

Most new laptops, netbooks, and even desktop PCs come with a Bluetooth radio, and if your computer does, you may still elect to use the Bluetooth option for its convenience and lack of clutter otherwise caused by extra cables on the desk. Even if your PC does not come with a Bluetooth adapter, you may purchase one at any computer store.

If Bluetooth is not an option, the USB cable serves as an excellent method of interfacing with a host device and offers the advantage that the display is always charged.

The best place to get specific instructions about connecting a braille display like Refreshabraille 18 will be with the software to which you wish to connect. For example, look in the documentation for Mobile Speak Smartphone if you plan to use the display with a smartphone running this screen reader software.

If Refreshabraille 18 is not a specific choice, which may be the case in older versions of screen reader software, you may be able to use Baum as an option. Choose a Baum display that features both braille cells and keys for input, such as the Vario Connect.

Bluetooth

There are two connection options for Bluetooth. The default setting is Auto which automatically performs a simple pairing to your selected bluetooth device. The Auto connection is mainly used for convenience and when there is only one bluetooth device in the near vicinity. Follow these steps for Auto pairing:

1. Turn on the Refreshabraille 18
2. Turn on the bluetooth device
3. Find and select the Refreshabraille 18 in the pairing list

Note: For Apple devices, the list is under the Accessibility section. For all other devices, the list is under bluetooth devices.

The second option for bluetooth connection is Secure. The Secure setting is a good option when using the Refreshabraille 18 in a heavy bluetooth area or when typing/reading confidential documents or information. Because Auto is the default, you need to select Secure in the System Menu by pressing the router button below the word Secure. To begin, follow the steps above (for Auto pairing). At this point, a random code will appear on both devices. Confirm that the numbers match by pressing the router button under the word Pair on the Refreshabraille 18 (the other option is Cancel). Follow the steps appropriate to confirm your particular bluetooth device. There is a 30 second window (in total) to confirm for both devices. Once confirmed, your Refreshabraille 18 is paired in the Secure setting.

Daily Use with Bluetooth

Once Refreshabraille 18 is paired with the computer or portable device, you may turn the display and braille support on or off at will. Depending on the screen reader, it will either automatically reconnect to Bluetooth, or you will have to provide a command to let the device know to use Refreshabraille 18 again. for example, on the iPhone you reestablish the connection by unlocking the phone. On Braille+, the act of turning Refreshabraille 18 off or on is enough to let the device know to use (or not use) the braille display. When connected to a Mac via Bluetooth, the act of turning on the display activates it with VoiceOver.

USB

To connect Refreshabraille 18 to a Mac already running VoiceOver, just attach the USB cable. VoiceOver automatically recognizes and starts using the display.

In most cases, connecting Refreshabraille 18 to a PC with USB is simple. The exception is when using Windows 7 and Windows 8. These interfaces require the installation of two drivers: one for the USB and one to make the USB port appear like a com port. The second driver is required because many screen reading programs handle braille displays like a serial device. (See the section Installing USB and Serial Drivers above.)

The com port assignment driver shows the port number it assigns to communicate with the display. You may want to take a note of it now; but if you need to look it up at a later time, go to Device Manager while the display is connected and look in the section for Ports: Com and lpt. One of the com ports is assigned to APH Refreshable Braille Display. You need to use that number when you set up your screen reader.

Configure the Screen Reader or Device

Once the display is connected to the device you wish to use, configure the software to use Refreshabraille 18.

Configure JAWS

If you use the JAWS screen reader and it is already installed, the Refreshabraille 18 setup program installs drivers to make the braille display and JAWS work together. If you have not already installed JAWS, install it first, then run the Refreshabraille 18 setup program. If running version 10 or earlier, install the rbd_jfw10.exe program to configure JAWS.

Start JAWS, and open its main screen. For version 11 or later, select the Braille item in the Options menu. Select APH Refreshabraille 18 from the braille display list. For versions earlier than 11, select the Braille option and then select APH Refreshable Braille Display 18, which is what gets added to JAWS when you run the rbd_jfw10.exe program.

Configure Window-Eyes

To use Refreshabraille 18 with Window-Eyes 7.1 or later, select Refreshabraille 18 from the Select Braille Display option in the File menu.

For versions prior to 7.1, there is no driver for Window-Eyes. However, you may use Refreshabraille 18 by selecting any Baum display with input keys. The Vario Connect and the Braille Connect are two that work.

To select a display, open the Braille Display option in Window-Eyes File menu. Select the display and set the com port number established by the drivers you just installed.

Configure VoiceOver on the Mac

When you connect the display, VoiceOver automatically recognizes the display and starts using it.

To control how VoiceOver treats the display, follow these steps:

• Open the VoiceOver Utility by pressing Command + F8 while VoiceOver is running.
• Scroll down to the Braille option.
• Select the Braille Display tab.

To turn on contracted braille, check the Contracted Braille box.

Configure NVDA

If you have NVDA installed on your PC, it may automatically recognize the Refreshabraille 18, depending on the settings. If it is not recognizing the display, go to the Preferences menu for NVDA and select Braille settings from the list. From the Braille Display drop-down menu, select Baum/HumanWare/APH braille displays and click OK.

Configure Mobile Speak Smartphone

To let Mobile Speak know which braille display to use, select Mobile Speak from the Start menu, then select Device Manager from the Mobile Speak menu. Use Vario Connect or Braille Connect as the display name.

Turn on Braille Support

After the display is connected to the device and the software on that device knows to use Refreshabraille 18, you may turn braille support on and off.

JAWS Support

JAWS turns on braille output when you configure it for the display. To turn off braille support, select No Display from the Options/Braille menu.

Refreshabraille 18 Commands for JAWS

Note: For a longer description of any of the following commands, turn JAWS keyboard Help on by pressing Insert + 1 and type the command. Quickly type the command twice to get an even longer description. Press Insert + 1 again to exit JAWS keyboard Help mode.

For command assignments for versions of JAWS earlier than 11, do the following:

1. Open the Start menu.
2. Select All Programs.
3. Select JAWS Braille Driver APH.
4. Select Keyboard Assignment.

The following applies to versions of JAWS 11 or later.

Type Keys mode allows you to type into the computer with the display. When in Type Keys mode, use space with commands that use dots 1 through 6. For example, pressing dots 1-4-5 deletes the current character. In Type Keys mode, hold down space with dots 1-4-5 to issue this command.

To discover all the keys Window-Eyes supports, select Hot Keys from the Window-Eyes Braille menu. A dialog appears listing all the functions and the keys to perform each function.

The System Menu

When you turn on Refreshabraille 18, the system menu appears on the braille display. The first line of braille displayed will either be 'APH' followed by the unique serial number for the unit or the display name you have assigned to it. In normal use, this is the only portion of the menu you see, because as soon as the connected device sends any data to the display, the menu gets replaced with that data. If, however, you wish to see the rest of the menu options, press the right advance bar. Each press of the advance bar moves to the next menu item, and the reverse bar moves to the previous one. These items include Serial Number, Battery Status, Bluetooth Name, and so on.

Exit Menu

There are two ways to exit the system menu. 'Menu Off' is the last item in the system menu. Press any of the cursor routing keys below the word 'Off' and the menu disappears. You may also use your PC or mobile device to communicate with the display and the system menu will disappear.

Many options in the menu present choices among two or more items. The currently selected option is indicated on the display by the raised dots 7 and 8. To select an option, press one of the cursor routing keys below the option to select.

When you exit the menu, Refreshabraille 18 automatically saves all your setting changes.

Re-enter the Menu

To return to the menu, follow these steps:

1. Press and hold the first and last cursor routing keys.
2. While still holding down the cursor routing keys, press and hold dots 7-8. Refreshabraille 18 responds with a vibration, and then the menu appears on the display.
3. Release all four keys.

Name of Display

The first line of the menu shows the name of the braille display. When you first turn on the Refreshabraille 18, the display reads APH and the unique serial number assigned to that device. For example, APH 27002968. The serial number is also what appears as the Bluetooth name for the device. You may edit this name to provide a more personalized greeting.

To edit the name, follow these steps:

1. Select the cell you wish to change by pressing the cursor routing key under it. Refreshabraille 18 responds by showing a cursor on the character.
2. Use the up or down position of the directional button to cycle through the available characters.
3. Use the left or right position of the directional button to move to the previous or next character.
4. Repeat steps one through three until you have the name you wish to assign to the Refreshabraille 18.
5. Press the first two cursor routing keys together to confirm the name.

Battery Status

The Battery Status option shows the amount of battery power available. The level is expressed as either 1, 2, or 3 full cells, with 3 being the most battery power and 1 the least. When the battery is very low, there will be no full cells.

Serial and Human Interface Device (HID) Protocols

A USB mode was added to any Refreshabraille 18 manufactured after March 2010. The USB mode requires the user to choose either the serial or HID protocol to communicate between the display and user device via the USB port.

Most earlier screen reader programs require a serial protocol setting. However, if your screen reader supports HID protocol, it could be a better choice. HID does not require additional external drivers; and, if you have the USB mode set to HID, Windows installs the drivers without the CD. If the USB mode is set to serial, Windows requires the CD the first time you connect to your PC so it can find the USB serial drivers.

Standby Time

Standby Time displays the number of minutes Refreshabraille 18 waits with no communication from the connected device before it blanks the display and enters its power saving Standby mode. When in Standby mode, Refreshabraille 18 wakes up when the connected device sends any data to the display.

There is a minus sign to the left of the number (in minutes) and a plus sign to the right of it. Press the cursor routing key associated with the minus to reduce the standby time, and press the router key associated with the plus sign to increase it. Set the standby time to zero to turn off the standby capability.

Automatic Power Off

Automatic Power Off (APO) determines the number of hours Refreshabraille 18 waits after entering Standby mode before it completely shuts down. As with the Standby menu option, this menu contains a plus and minus sign. Press the cursor routing key under either of these characters to change the value.

Advance Bars D R

The advance bars are located to the left and right of the aux space bar, between the braille input keys and the braille cell display. The two setting choices are listed below:

• D (default): Right advance bar scrolls forward; left advance bar scrolls back
• R (reverse): Left advance bar scrolls forward; right advance bar scrolls back

Bluetooth Auto Sec

There are two connection options for Bluetooth. The default is Auto pairing.

• Auto: performs a simple pairing automatically
• Sec (secure): performs a secure pairing with code confirmation

Firmware Version

The firmware version number represents the level of software running on the Refreshabraille 18.

Serial Number

Serial number displays the serial number for the device. This is a unique number and is not editable. You use the number to keep track of a specific device for maintenance or warranty purposes.

Default Settings

Press any of the cursor routing keys under the word 'default' to restore all settings to their defaults.

Menu Off

Press any of the cursor routing keys under the word 'off' to exit the menu.

Self-test

In the System Menu, press the first two and the last two cursor routing keys on the braille display. The display responds by activating each dot of each cell, one after the other, and then clearing them.

To clear the self-test, press the first two and last two cursor routing keys at the same time.

Reverse the Display

Refreshabraille 18 features the ability to 'flip' the display, allowing the user to have the braille cells at the bottom or top of the device. To flip the display and controls, press both the Reverse and Advance bars at the same time. Refreshabraille 18 responds immediately, so you may rotate the device 180 degrees and use it in the new orientation for both reading and input.

When Refreshabraille 18 is oriented with the cells closest to you, the Aux Space may be used as the space key. The Aux Space is located between the two advance bars. However, some users may find it just as convenient to use the space bar which is now located (unconventionally) above the braille dot keys.

Display Keys

Some programs use what they call Display keys on the braille keyboard to perform various functions. These are usually six small round buttons that supplement the things you can do with the normal keys.

Refreshabraille 18 uses a key combination to produce the Display keys. The combination consists of pressing and holding down the center of the directional button while you press the dot numbers of the braille keys. For example, to produce the combination for D2-D3, you would press Center + Dots 2-3.

Firmware Updates

Refreshabraille 18 is designed so that updating to the latest version is easy. If updates are available, you may download firmware updater software at tech.aph.org/rbd_upd.exe, which contains both the new firmware for the display and the code to install it.

When you click on the download link, the firmware updater will automatically detect your device, detect your firmware version, and update if a newer version is available.

In order to have the firmware updater see your device, it must not be paired with a screen reader, or at least not have it selected as the device in use at the time. For example, if you are using JAWS as your screen reader, JAWS would need to be set to 'no selected device.'

If your device is in HID mode, the update should work. To update your device in Serial mode, the serial drivers must first be installed.(See the Installing USB and Serial Drivers section of this document.)

Accessories

Executive Products Inc. sells a carrying case for Refreshabraille 18. See the Executive Products Inc. website for additional information.

Bapin Group, LLC also sells a leather carrying case with a strap. See the Bapin Group website.

Help with Malfunctions

Minor things can happen which visibly affect the performance of a braille display but which cannot be called a 'real' malfunction. A few examples and helpful hints are described below.

• The braille display shows no characters.
  • Check that the device is switched on.
  • Has a program been launched which is accessing the port of the braille display?
  • Was the correct port selected when the screen reader was loaded?


• After turning on the braille display, there is no reaction from the display either when the System Menu is called up or when a computer application is launched.
  • The battery may be discharged; charge the device and try again.
  • If Refreshabraille 18 does not react, turn it off and wait 2 minutes before you turn it on again. If the System Menu is still not displayed or the pins flicker quickly, please contact the APH Service Department.


• Refreshabraille 18 is turned on and the display suddenly stops reacting.
  • The automatic power off time limit has been exceeded. Turn the display on again and move the cursor to update the display.


• The display stops reacting to key commands and the braille does not change.
  • Is the display out of range for the Bluetooth radio? If you move the display more than 20 or 30 feet from the device to which it is paired, the display cannot communicate with the device. Move closer to the paired device. Most devices and software automatically resume communication when back in range.
  • Did you turn off the device? If you power off the device to which Refreshabraille 18 is connected, they may no longer communicate. Turn the device back on and initiate any commands necessary to reestablish a braille mode.
