# 1 Introduction

The Orbit Reader 20 Plus is a portable, refreshable braille display and stand-alone reader with the following features:

· A line of 20 braille cells with pins that arrange into the required pattern to accurately represent any six- or eight-dot braille code, in any language, and for any discipline

· Reads the contents of files on an SD™ (Secure Digital) card Stand-Alone Mode

· Remote connectivity to PCs and mobile devices for use with a screen reader

· On-board translation from text to braille and from braille to text

· On-board support for contracted braille

· On-board support for over 40 languages, including UEB

· Simple editing functions

· Onboard utilities such as Calculator, Calendar and Alarm

· Signage-quality braille

# 2 How the Orbit Reader 20 Plus Is Used?

## 2.1 Stand-Alone Mode

Content stored on an SD card is read in one of three ways:

· Sent by library

· Prepared on a computer and copied to the device

· Using onboard translation

In Stand-Alone mode, the Orbit Reader 20 Plus displays the contents of files stored on an SD card. It supports text to braille and braille to text translation on-board for English and over 40 other languages. For English, it supports translation to and from contracted and uncontracted braille. In addition, it can be configured to translate contracted braille in other languages. Please refer to the Localization section in this guide for more details.

## 2.2 Remote Mode

Connect the device to a computer or mobile device with a screen-reader and then do one of the following:

· Read commercially available titles on Kindle™, Adobe® Digital Editions, or Apple Books® application programs.

· Employ any accessible technology for browsing, utilities, and education.

The screen reader translates text into Braille code of choice.

Important: The Orbit Reader 20 Plus is designed to automatically exercise the braille dots if has been idle for more than 24 hours. This helps keep the dots running smoothly and prolongs their life. All dots are raised and lowered three times during the exercise cycle, which takes about 3 seconds to complete. If the device continues to remain idle, the cycle will repeat every 24 hours, approximately.”

# 3 Transcribed Braille

There are multiple sources for files that are transcribed into high-quality braille. Below are some examples:

· National Library Service (NLS) provides professionally transcribed, formatted files through the Web Braille project.

· RNIB Reading Services offers professionally transcribed braille titles.

· National Braille Press (NBP) produces braille books, textbooks, tests, and information for adults and children.

· Louis Database lists titles produced by over 160 organizations.

· American Printing House for the Blind (APH) transcribes textbooks for K-12 students.

# 4 Automatic Translation

In addition to professionally transcribed titles, you may also use dynamic translation to obtain braille.

Automatically translated braille may be appropriate for some forms of reading.

· Bookshare® dynamically generates braille formatted files from the titles in its library.

· Sugamya Pustakalaya is India's first and largest collection of accessible books. Users can access a collection of over 3,28,900 books, maintain their individual reading shelves online and download books in chosen formats.

· NFB-NEWSLINE® is a free audio information service, providing downloadable Braille files of up-to-the-minute content from over 400 national, international, and state newspapers.

· RNIB Reading Services offers electronic braille books for download to UK customers

# 5 Translate Braille

· The Orbit Reader 20 Plus features built-in forward and reverse braille translation. This is controlled by the profile selected from the menu

· BrailleBlaster™ is a full-featured transcription software package for creating quality formatted braille.

- DAISY™ Pipeline provides a comprehensive solution for converting text documents into accessible formats.
- Send to Braille is a shortcut that adds braille to the Windows® Send To menu, which can convert files on your computer into unformatted BRF (Braille Ready Format) files.

# 6 Documentation Conventions

For consistency and clarity, we have used the following conventions in this document.

Braille keys are indicated by number. For example, if the documentation indicates Dot 1, it shows: Dot 1.

If multiple braille keys are required, the documentation indicates those keys by showing the numbers separated by a space like this: Dots 1 4.

When modifier keys are used, the documentation separates the modifiers from the rest of the keys with a plus (+) sign like this: Space + Dot 1. Modifiers like the Shift key on a regular QWERTY keyboard, are keys you hold down while pressing another key. This modifies the effect of the pressed key. On a braille keyboard, Space is often used as a modifier key to alter the effect of the input keys. Key mnemonics are written in capital letters for emphasis but are typed in braille lowercase (unless otherwise stated). When one key follows another, the two keys are shown with a comma between them. For example, the command Select, M means to press and release the Select key, then press and release M (Dots 1 3 4) simultaneously.

The Up, Down, Right, and Left directional buttons on the navigation pad are interchangeably referred to as arrows, buttons, arrow buttons, and arrow keys.

All messages from the device are preceded with Dots 2 5, 2 5 and a space. In the documentation, this is indicated by a double hyphen.

The words Keys and Buttons are used interchangeably.

In the descriptions of each Menu option, this documentation indicates the default setting.

Any reference to navigation by “page” while in Stand-Alone mode only means navigation by 1000 characters (page = 1000 characters).

# 9 Orientation

The orientation of buttons, keys, cells, and slots is important for understanding how Orbit Reader operates and how you input and receive information on your braille display.

To begin with, place the device on a flat surface in front of you with the row of braille cells closest to you. This is the proper operational orientation.

As you reach around from the front to the back of the device, from left to right, there is the Power button (left), an SD card slot (middle), and a Micro-B USB port (right). They are all recessed in an area in the left half of the back edge (facing away from the user). The Power button sticks out enough to make it easy to identify. The SD card slot has two small bumps directly below it and the USB port has one bump below it (shown in the picture below).

The SD card slot is a standard type with spring feedback. The SD card is inserted with the card connector fingers facing down. To release the card, press in and remove your finger to allow the card to pop out.

The battery compartment is located on the bottom of the device.

## 9.1 Key Location and Use

When properly oriented, the space bar is closest to you. The panning keys are at each end of the braille display. See the Panning Keys section for more information. Below the space bar are the braille cells.

For orientation purposes, there are three slightly raised tick marks located above the braille cells. These orientation marks are spaced at every fifth braille cell. For example, the first tick mark from the left is between the fifth and sixth braille cell.

Moving toward the top and away from you, find a row of three keys, with a wider

one - in the middle. The wide key is the Space bar. The Dot 7 input key is to the

left of the Space Bar, and the Dot 8 input key is to the right of the Space Bar.

As you continue toward the top of the face of the display, there is a navigation

pad in the middle, between the Braille Input keys and Space bar.

The navigation pad contains the four directional arrow buttons (Up, Down, Left,

Right) and the Select button.

The six traditional braille input keys are aligned horizontally along the top edge of

the face of the display, Dots 3 2 1 on the left and Dots 4 5 6 on the right.

In Stand-Alone mode, the braille input keys are used for navigation and editing/writing.

In Remote mode, while using the display with a screen reader on a host device, like an iPhone, the braille input keys can be used to input text or control the functionality of applications on the host device.

## 9.2 Panning Keys

The Panning keys are two-function rocker keys found at either end of the braille display. These keys control how you read the lines of the text: either next or previous. Pressing on one end of the key results in one action, while pressing on the opposite end results in the opposite action.

To read the next display of text (panning forward), press the bottom part of the key (down) on either Panning key. To read the previous display of text (panning backward), press the top part of the key (up) on either Panning key.

## 9.3 8-Dot Braille Cells

The Orbit Reader 20 Plus is a six-dot braille device with two additional dots below Dot 3 and Dot 6. These two additional dots are Dot 7 and Dot 8, which are used to indicate capitalization while reading and editing the file in 8 dot mode. These dots also indicate a selected item in the menu, text with attributes or accent marks or a cursor. Their exact use depends on the application you use with the display.

# 10 Getting Started

The Orbit Reader 20 Plus has two modes: Stand-Alone mode and Remote mode. In Stand-Alone mode, the device is a book reader that uses an SD card as storage media. In Remote mode, the device works like a braille display and needs to be connected to a computer or other host with a screen reader.

This section explains how to charge, turn the device on and off, insert the SD card, and enter and exit the menus.

## 10.1 Charging the Device

When you receive the Orbit Reader 20 Plus, it may be already charged; however, we recommend that it should be fully charged before or during first use. You can use the device and charge it at the same time, so it saves reading time. When the battery in Orbit Reader 20 Plus gets to 10% of its capacity, Dot 8 of the 20th cell on the display starts blinking on and off. This behavior is normal and indicates that the battery is low.

To charge the device, use the Standard-A to Micro-B USB cable and the charger power plug provided with the unit. Insert the small end of the cable into the Orbit Reader 20 Plus's USB port. It should slide in without resistance; do not force it. Now insert the large end of the cable into a computer’s USB connector or the AC adapter provided. Plug the adapter into an AC wall connector.

If the device is on when you connect the charger, the display shows "-- Charger connected". When you unplug the charger, it shows "-- Charger unplugged". The charger plugged and unplugged indications are displayed briefly even when the unit is off. The language of the message depends on the language you select for system messages from the menu. By default, the language will be UEB Grade 1 (uncontracted).

For more information, see the Battery section under the Menu.

If you have charged the device for 4 hours or longer, and it does not power on, contact Customer Service at techsupport@orbitresearch.com

## 10.2 Power On and Off

A square Power (on/off) button is located on the back of the device. See Orientation section for more information.

To power on the device, press and hold the power button for 2 seconds. If for some reason the powering on process takes more time, the Orbit Reader 20 Plus flashes the braille cells from left to right to let you know that it is powering on.

When you turn the device on, the Orbit Reader 20 Plus resumes from the place you left. If you are using the device or inserting the SD card for the first time, the , Orbit Reader 20 Plus shows the first file or folder name on the SD card.

The Orbit Reader 20 Plus displays, “-- No SD card" when the SD card slot is empty.

To turn off the device, press and hold the Power button for two seconds. The braille cells flash from left to right to indicate the device is powering down.

The Orbit Reader 20 Plus has a low-power standby/sleep mode. Quickly tapping the Power button puts the unit in sleep mode. Tapping the Power button while the device is in sleep mode, wakes the device. While editing or when connected to Bluetooth, if no keys are pressed for an hour, the unit automatically goes into sleep mode. Otherwise, the device goes to sleep after 10 minutes of inactivity. After five hours in sleep mode, the unit shuts off to conserve power.

## 10.3 Inserting and Formatting the SD Card

The device comes with an inserted SD card with translated braille files already on it, so that you can quickly learn to use the device by reading the material.

The Orbit Reader 20 Plus uses standard full-size SD cards from 4GB to 32 GB in capacity. The card must be formatted as FAT32. There is no way to format a card on the device. Most cards come already formatted. However, you can format one as FAT32 on a desktop computer for use with the Orbit Reader 20 Plus.

To insert the SD card, find the large slot at the back.

On one of the short sides of the SD card, there are some ridges called fingers or teeth. Position the SD card with the teeth facing down. Now insert the short side with teeth into the device. The SD card should go in smoothly until it gets about a quarter of an inch from being fully in the device. At this point, you feel a slight resistance. The card slot works like a toaster, gently push the SD card in until you hear a click. The card is aligned with the rear edge when properly inserted.

To remove the card, press it in a little until it pops out and then gently remove it.

## 10.4 About Menus and File Names

The Orbit Reader 20 Plus shows internal menus and file names according to the language selected from the menu.

## 10.5 Entering and Exiting Menus

# 13 File Manager

The File Manager is where you select a file stored on the SD card to read on the Orbit Reader 20 Plus. You can also create new files and folders, view the properties (such as the file size and current reading position) and copy, rename, and delete files.

When moving through the list of files, the Orbit Reader 20 Plus shows the first 20 characters of the file name. You may scroll to the rest of the information about the file, such as the rest of a long file name, its size, and date, by using the panning keys to move the display window. You can change the way files are sorted in the file list using related menu options.

Each item on the file list includes the following items:

· Filename and extension

· The current reading position in the file as a count of characters

· Size in KB (kilobytes)

· Last modified time

· Protected or Unprotected

Only one column is displayed per line (with panning as necessary). Pressing Left or Right Arrow moves to the previous or next column heading (file information). Upon exiting the Reader (Dot 7), you are returned to the same place and column in the File Manager.

The language of the file name is displayed according to the system language.

There are several excellent braille translation systems available in the U.S. If you obtain textbooks from APH or get transcribed titles from NLS or NBP, the braille should be correct and formatted. You may also get braille translation software that produces automatically translated braille using programs like ‘Liblouis’. Alternatively, you can have Bookshare automatically generate braille files of the titles available.

## 13.4 Preparing Files

To prepare BRF files for placement on the Orbit Reader 20 Plus, follow these guidelines:

- Determine the translation type.
- Translate the file.
- Place the file onto the SD card or use the Mass Storage protocol to copy from your desktop computer.

To copy files to the SD card, remove the card from the Orbit Reader 20 Plus and place it into a card reader on your computer.

Press Dot 7 to close the file and display File Manager, which shows a list of files on the SD card. If there is no SD card inserted, the message "-- No SD card" is displayed.

When you open a text file to read for the first time on Orbit Reader 20 Plus , the file gets translated first as per the language selected for Reading/Editing. For a large file, it may take a few seconds to complete the translation. The translation process is indicated by showing a progress bar on the display where the Dot 6 (6th pin) of the first 6 cells raises in sequence, repeatedly.

The Orbit Reader 20 Plus stores the translated files in the SD card so that it can be used in the future. Latency is observed only when you open the file for the first time or if the translated file is lost for some reason.

While the file translation is in progress, no other operations are allowed and pressing any key will have no effect.

If translation is taking too much time and you wish to abort the operation, you can do so by pressing Dot 7. The system will cancel the file opening operation and will take you back to the file manager.

You can switch the reading language with the help of hotkeys, even if you are in the middle of the file. Please note that if you change the language, the system will translate the file again as per the new language selected.

When you reach the end of the file, "-- End of file" is displayed by the Reader. Similarly, if you are at the beginning of the file, "-- Start of file" is displayed.

Press Select twice to return to the file you were reading.

## 14.2 Power Move Forward and Back

The Orbit Reader 20 Plus's power move commands provide a quick means of moving/searching through large sections of a file to find a known location in the document. A power move operates by using boundaries and moving 50% between them with each press of the key command. In essence, by using a power move to search within a file, you are drilling down to the information using a binary command. When you press Dot 8 + Down Arrow or Dot 8 + Up Arrow, the Reader moves in the following ways:

On the first press, the cursor moves halfway between the current position and the start (Dot 8 + Up Arrow) or end (Dot 8 + Down Arrow) of the file, which acts as the boundaries for the power search.

Subsequent presses treat the moved-from position as the new boundary in that direction. So, if you are at the beginning of the file (or 0%) when you press the Dot 8 + Down Arrow, the Reader moves the cursor to halfway between 0% and 100%. You are now at 50%, and this becomes the new boundary. The initial boundary is at the original position of 0%. Therefore, if you press Dot 8 + Up Arrow, you move halfway between 50% and 0% to end at 25%. Or, if you press the Dot 8 + Down Arrow, you move halfway between 50% and 100% to end at 75%.

Each time you press Dot 8 + up arrow or Dot 8 + down arrow keys, the Reader shows the percentage in the first few cells of the display line and fills the rest of the cells with text at that position. This continues until you press some other key. See the Panning Keys Section for more information.

## 14.3 Find Braille

To find specific braille text, use the Find command (Space + F). The Orbit Reader 20 Plus responds by opening an input field (see Edit Box section) with a cursor, which is indicated by Dots 7 and 8. By default, it shows the text at the current cursor location in the edit box. Unlike the Power Move, which searches by known location of text, the Find command searches the entire file for instances of the braille text you enter in the input field. If you have searched for something previously, that text appears in the Edit Box with your cursor at the end. See the Power Move Forward and Back section for more information.

To find a word, first press Space + F to enter the Edit Box. Type the word you wish to find, in the language selected for the reader/editor and then press Dot 8 to start the search moving forward in the file. To search moving backward in the file, press Dot 8 + Left arrow. The word is shown as the first word on the display. If the word is not found, the message "-- Not found" is displayed. Press Dot 7 to clear the message. To exit the Edit Box without finding the word, press Select.

After the word is found, to continue searching, press Dot 8 + right arrow to find the next occurrence (forward in the file) or Dot 8 + left arrow to find a previous occurrence (towards the beginning of the file).

If you are searching for text in a contracted braille file, you must type the text you want to search in contracted braille.

If you are searching in a plain text file, you must type the text you want to search in Computer Braille. See Appendix A - Computer Braille Chart for details.

You can search for terms up to 255 characters long. Searches are generally not case sensitive. A search for the word "animal" results in finding both lowercase and uppercase versions of that word (animal/Animal). However, if you want to find words with upper case letters only, type the text you wish to find with the braille indicator for capitalization included (in contracted braille, one Dot 6 precedes a capital letter, while two Dot 6s precede an entirely capitalized word. In Computer Braille, capital letters include Dot 7). For example, a search for the capitalized word "Animal" gives the results for "Animal" (capitalized), but not "animal" (lowercase).

Additionally, searches match both whole and partial words. Searching for "an" finds "an" (whole) and "man" (partial). To restrict searches to whole words, add a space at the beginning or end of the word. The Reader matches the space with any non-printing character such as spaces, tabs, and line feeds.

Read the section on Edit Box for editing commands and navigation functionality.

In” search files”, the Reader moves from reading files to searched text and displays it at the beginning of the display line. If the text is not found, then the Reader displays “Not found” and gets back to its previous position. While searching through large documents, the Orbit Reader 20 Plus displays “Busy” while conducting the search.

To repeat a search moving forward towards the end of the file, press Dot 8 + Right Arrow.

To repeat a search moving back towards the beginning of the file, press Dot 8 + Left Arrow.

## 14.4 Braille Pacer (Auto-Scroll)

The Braille Pacer feature is available in the Reader and lets you set a reading pace for the display to automatically advance.

The pace can be adjusted during reading by pressing the space and Up-Arrow

key to increase the speed (i.e. a faster advance rate) or the space and Down-Arrow key to decrease the speed (i.e. a slower advance rate). Pressing these keys once increases or decreases the speed in one-second steps. You can set the scrolling speed from 1 to 20 seconds depending upon your reading speed.

Many users might like to have finer control of the speed and this can be achieved by pressing the space bar, dot 7 and up or down arrow keys. The fine control increases or decreases the speed in steps of one-tenth of a second.

The default speed is 4 seconds. You can review the current scroll rate from the menu, but it can be changed only while reading. The current scroll rate is not displayed when auto-scrolling. However, when the auto-scroll is stopped and the scroll rate is changed, the scroll rate will be displayed by the message “xx.y sec scroll rate”. You can use all the reading navigation commands during the Braille Pacer mode as well.

To Start/Stop Braille Pacer, press Space. The rate of change is not viewable if the speed is increased or decreased while active.

To Increase/Decrease Speed by 1 Second, press Up or Down Arrow + Space

To Increase/Decrease Speed by 0.1 Second, press Dot 7 + Up or Down Arrow + Space.

# 15 Edit Box

The Orbit Reader 20 Plus presents a text dialog or input field called an Edit Box when you want to find text or rename a file. The Edit Box permits only one line of text. Press Space + F to begin a search or press Space + R to rename a file.

Once in the Edit Box, insert the text by typing the desired text as per the language selected for the reader/editor and then use the Edit Box commands to navigate. The Edit Box displays a blinking cursor (Dots 7 8) to indicate the beginning of the text that you are searching or editing. When the Orbit Reader 20 Plus shows an edit box, it often provides default text, such as a file name or a previously entered search term. To delete or replace the selected text, type a letter or press the backspace key (Dot 7). To edit the existing text in insert mode, press one of the arrow keys to move the cursor letter by letter to the position where you wish to edit.

## 15.1 Edit Box Commands

To Move Left or Right One Letter, press Left or Right Arrow. Pressing left or right arrow moves the cursor in the desired direction. When the cursor reaches the end of the edit box, it stops--it can move no further.

To Move to Start or End of Text, press Up or Down Arrow. Press Up or Down Arrow to move the cursor to the beginning or end of the text.

To Backspace, press Dot 7. The Backspace key Dot 7 deletes the letter immediately left of the cursor. Use Backspace key in case of a typing mistake or to remove small amounts of text.

To Accept typed text, press Dot 8. Here, pressing Dot 8 acts as an Enter/OK key.

To Close the Edit Box, press Select. To close the edit box, use the Close command. In single line controls, Close removes what you have typed. In multiple line controls, all text is automatically saved in the editor.

# 16 The Editor

In addition to serving as a tool for reading braille, the Orbit Reader 20 Plus offers the ability to write and edit text. This feature allows you to create/edit new or existing files on the SD card.

While you are in the Editor mode, the cursor notes the current position by blinking Dots 7 8. The default setting for the cursor is 1 second. The blink of the cursor can be turned off from the Menu.

There are three ways to edit a file. Each of these three commands is available both from the Reader and the File Manager.

· Edit new file: Space + N

· Edit current file: Space + E

· Switch to last edited file: Space + Dots 1 2 4 6

To insert text, type or paste the text at the cursor. You can insert any text into an open file using the braille keys (Dot 1 to Dot 8). The Editor adds the typed or pasted text.

To exit Editor, press Select, E or Select twice. The cursor disappears, returning you to the Reader in the file you were editing.

When you exit the editor or save the file from the context menu, the back translation from braille to text is performed as per the selected language. The translation process is indicated by showing a progress bar on display where the Dot 6 (6th pin) of the first 6 cells rises in sequence repeatedly. This operation cannot be canceled.

If you are exiting a new file, the editor automatically names the file with the first 20 characters of the translated text in the file. If a file already exists with that name, the Editor appends a number to it until it produces a unique name. To rename a file or to add an extension to the file name, highlight the file name in File Manager, and use the rename command. If there are Computer Braille characters that cannot be used in a filename, such as a forward slash (/) or an asterisk (*), the characters are replaced with an underscore (_). Once you exit, the new file name in the File Manager is selected. If you wish to rename the file, use the rename command (Space + R). If you want to give the file a specific name, write that name as the first line in the file.

Note: It is recommended that you exit the Editor before you perform a system update, reset the device, or remove the SD card. Exiting the Editor saves your work. Not exiting the Editor first could result in lost work.

## 16.1 Editor Commands

To Edit New File, press Space + N. Creates a new file in the Editor, ready for input.

To Edit Current File, press Space + E. Opens the selected file for editing.

To Switch to Last Edited File, press Space + Dots 1 2 4 6. Opens the last edited file for further editing. The device displays the error message "-- File not found" if the file has been deleted.

To Add a new line (Enter), press Dot 8. Pressing Dot 8 adds a new line (enters a carriage return) at the end of a paragraph and places the editing cursor in the first cell of the next paragraph.

To Delete a character, press Dot 7. Pressing Dot 7 deletes the character to the left of the editing cursor.

To Exit Editor, press Select twice OR Select, E When you close a file, Editor saves and returns to the Reader or File Manager, depending on your earlier location. It automatically saves your work. If you have opened the file from File Manager, File Manager makes the new file the current item in the list. If you edit an existing file, Reader moves the reading position to the place where the cursor was.

To Save current work, press Select, S. The Orbit Reader 40 automatically saves files every 1 KB of data or about 1000 characters, as you edit. However, small file increments could be lost during certain situations such as SD card removal, system updates, or device resets. Pressing Select, S saves the file as you deem necessary.

To Go to next or previous character, press Left or Right Arrow. Pressing Left or Right Arrow moves the cursor to the previous or next character.

To Go to next or previous word, press Space + Left or Right Arrow. Pressing Space + Left or Right Arrow moves the cursor to the start of the previous word or next word. This is also used to navigate between digits.

To Go to Previous or next display, press Pan Up or Down. Pressing Up or Down on the Panning rocker keys allows you to move to the previous or next display of braille. If you press the bottom part of the rocker key, the display pans forward. If you press the top of the rocker key, the display pans backward. The editing cursor is placed at the first cell. See Panning Keys section for more information.

To Go to Previous or next paragraph, press Up or Down Arrow. Pressing the Up or Down Arrow moves the editing cursor to the start of the previous or next paragraph. If the start of the previous or next paragraph is not on the display, then the display pans to the start of the previous or next paragraph to the first cell on the display. The editing cursor is placed in the first cell.

To Go to Start or end of paragraph, press Space + Dot 7 + Left or Right Arrow. Pressing Space + Dot 7 + Left or Right Arrow moves the cursor to the start or end of the current paragraph. If the start or end is not on the current display, then the display pans to the start or end of the first cell of the display. The editing cursor is placed in the first cell.

To Go to Previous or next page, Space + Dot 7 + Up or Down Arrow. Pressing Space + Dot 7 + Up or Down Arrow moves the cursor to the previous or next page (1000 characters or form feed character).

To Go to top or end of the document, press Long Press Up or Down Arrow. Long pressing Up or Down Arrow moves the cursor to the top or bottom of the document.

To Find Next Braille, press Dots 8 + Right Arrow. Pressing Dots 8 + Right arrow repeats a previous search forward from the point in the file where you are. If there is no text in the Find Edit buffer, the Editor uses the text at the cursor.

To Find Previous Braille, press Dots 8 + Left Arrow. Pressing Dots 8 + Left arrow repeats a previous search backwards from the point in the file where you are. If there is no text in the Find Edit buffer, the Editor uses the text at the cursor.

## 16.2 Editor Block Text Commands

The Editor block operations depend on a selection. The selection is the text between the cursor and the location mark.

Note: The size limit for a cut/copy/paste operation is 5 KB of data.

Adding a location mark does not change the content. Marks are used for copying/cutting a selection of text. To copy or cut using marks, press Select, M to place a mark. Only one mark can be placed/added at a time. Once the mark is placed, the text between the cursor and the mark can be copied (Select, C) or cut (Select, X). Once text is copied or cut, the mark is cleared.

To Set or clear Location Mark, press Select, M. The editor indicates a mark by raising both Dots 7 and 8 on the character where the mark occurs. To set or clear a mark in the file, press the Mark command. If there was already a mark at the cursor, the editor shows "-- Mark cleared" on the display and removes the mark. If there was no mark, it shows -" Mark set" and adds a mark.

To Copy, press Select, C. The copy command places the selected text onto the clipboard for later use in this file or another file.

To Cut, press Select, X. The cut command removes the selected text from the document and places it onto the clipboard for later use. If you want to put that text somewhere else, move to the desired position, then use the Paste command.

To Paste, press Select, V. To paste the contents of the clipboard before the cursor, use the Paste command.

## 16.3 Context Menu

The Context menu gives you quick access to the functions such as cut, copy, and mark for use in Editor.

While in Editor, press Select to open the Context menu. There are two ways to make a selection from the Context menu after it is open.

1. If you do not know the braille shortcuts, press the Up or Down Arrow key to scroll to your selection and press Select or Dot 8.
2. If you know the braille shortcut for the command (the braille letter associated with the function), press that letter.

· E Exit

· M Mark

· C Copy

· V Paste

· X Cut

· F Find

· S Save

You can also press Select twice to quickly exit the Editor. The first press opens the Context menu; the second press selects the first option in the menu, which is Exit.

# 17 Remote Mode

In addition to using the Orbit Reader 20 Plus as a portable reading tool and editor, it connects with host devices (i.e., computers, phones, tablets), and the Orion TI-84 Talking Graphing Calculator (https://www.orbitresearch.com/product/orion-ti-84-plus/) to provide braille input/output to and from the device. The host device must be running software that supports braille.

· Windows PCs - JAWS®, NVDA, Windows Narrator, System Access, Window-Eyes, Dolphin Screen Reader™,

· Mac® computers and iOS® devices - VoiceOver

· Android devices - BrailleBack, Braille TTY, Amazon VoiceView

· Chromebook - ChromeVox

When you use the Orbit Reader 20 Plus as a display for other hosts, the screen reader on that host device provides translation and other braille settings. Refer to documents for the specific screen reader you are using.

The only hotkeys used with Remote mode that are not sent to the remote device are:

- Pressing Select + Up Arrow opens the Orbit Reader 20 Plus Menus.
- Pressing Select + Left Arrow returns the Orbit Reader 20 Plus to Stand-Alone mode.
- Pressing Select + Right Arrow returns the Orbit Reader 20 Plus to Remote mode.
- Pressing Select + Down Arrow brings up an Edit box where you can type and submit up to 255 characters of text to the remote device. Press Dot 8 to submit or Select to cancel.

## 17.1 Before you Connect

Before you connect the Orbit Reader 20 Plus to a host, it is important to set the device so that the screen reader(s) you use, recognize it. Newer versions of screen readers recognize the Orbit Reader 20 Plus. The table below shows the first version of the screen reader to directly support Orbit Reader 20 Plus.

· VoiceOver on IOS with version 10.2

· VoiceOver on Mac with version 10.11

· Brailleback with version 0.97.0.205156277

· BRLTTY with version 5.5

· NVDA with version 2017.1

· ChromeVox with version 61.0.3163.120

· Voiceview with version 5.6.0.1

· System Access with version 3.7.85

· Dolphin Screen reader with version 16.05

· Sunshine with version 9.0.5575

If you have an earlier version of a screen reader, or one that does not yet support Orbit Reader 20 Plus, you must set Orbit Reader 20 Plus to emulate Refreshabraille 18.

Note: In Refreshabraille 18 emulation mode, only the first 18 braille cells are used.

To set the device to emulate Refreshabraille 18, select Emulation from the Orbit Reader 20 Plus menu and select RB18. If you plan to connect multiple host devices and any of your preferred screen readers do not support the Orbit Reader 20 Plus, you must use the same emulation setting for each host. Note that if you already have emulation set and you want to change the setting, you must disconnect the device from the host first. Temporarily turn off your screen reader's braille support before altering the setting.

If you have paired the Orbit Reader 20 Plus with Emulation off, unpair it from Bluetooth connections before using it again.

## 17.2 Using the Bluetooth Connection

Bluetooth is a technology that wirelessly connects devices, such as the Orbit Reader 20 Plus, to host devices, such as phones, tablets, and computers. For example, when using an iPhone with VoiceOver, you can control the iPhone with keys and buttons on the Orbit Reader 20 Plus, and you can read the entire interface in braille as you interact with it.

If the Orbit Reader 20 Plus is on, when you turn on the host device, it connects automatically provided the Bluetooth option in the menu is set to Automatic. When the host device enters sleep mode or is turned off, the Orbit Reader 20 Plus reverts to showing stand-alone content. When connected to another device through the USB port, reconnects to screen reader on the other host device.

There are only two ways to wake up a host device:

· Pressing the Power button

· Receiving a notification

Before you can take advantage of Bluetooth, you must perform the one-time procedure of pairing the Orbit Reader 20 Plus with the host device. With newer devices, the Orbit Reader 20 Plus makes pairing easy by employing a Bluetooth profile named "Just Works." If you use an older host device that does not support this profile, you need to alter this setting in the Orbit Reader 20 Plus's menu.

If you set Emulation to RB18, it shows up in the remote device pair list as Refreshabraille#### (where the # sign represents the last four digits of the serial number of your Orbit Reader 20 Plus).

To pair the Orbit Reader 20 Plus to a host device, see the Bluetooth section for the device type.

· Connecting iOS with Bluetooth

· Connecting Mac with Bluetooth

· Connecting Android with Bluetooth

· Connecting Windows with Bluetooth

## 17.3 Manage Connections

When you use Bluetooth, it is possible to interrupt the Orbit Reader 20 Plus activities with a connected host device. Each time you wake up the host device, it takes over the Orbit Reader 20 Plus. This behavior makes it very convenient to interact with your host in braille, but if you use the Orbit Reader 20 Plus in Stand-Alone mode or connect it to a screen reader with USB, you may not want the interruption when your phone wakes up. To return the Orbit Reader 20 Plus to what you were doing before the interruption, put the host back to sleep by tapping the Power button.

To prevent interruptions from occurring altogether, turn off Bluetooth in the Orbit Reader 20 Plus menu or temporarily turn off notifications on the host device. When you are ready to resume using Bluetooth, either turn it back on from the Orbit Reader 20 Plus menu or use the hotkey Space + Dots 4 7 from Stand-Alone mode on the Orbit Reader 20 Plus. (You can always return to Stand-Alone mode by pressing Select + Left Arrow on the Orbit Reader 20 Plus.)

### 17.3.1 Connect to Multiple Hosts

It is possible to pair the Orbit Reader 20 Plus with more than one device. For example, you can pair it with both your phone and tablet. The device you use must offer a braille interface.

To use Bluetooth with multiple devices, the screen reader on each of the devices should be set to work with the same emulation setting. In other words, if you have an iPad with software version prior to 10.2, it will not recognize the Orbit Reader 20 Plus. Therefore, you should set Emulation mode to be compatible with the older version. If all the hosts you are using support the Orbit Reader 20 Plus directly, turn Emulation mode off. If any of them does not support the Orbit Reader 20 Plus, set the Emulation mode for all to RB18.

While it is possible to pair a device with Emulation off and later pair to a second device with Emulation on, if you set the emulation differently between the devices, commands will fail to work correctly. Therefore, it is important to pay particular attention when the Orbit Reader 20 Plus is set to be used with multiple devices. The first device appears to work, but it does not function correctly, because it still uses the Orbit Reader 20 Plus commands instead of Refreshabraille commands.

When connecting to host devices that do not support the Orbit Reader 20 Plus to ensure the proper functioning of commands between the Orbit Reader 20 Plus and host devices, Set Orbit Reader 20 Plus to emulate RB18.

Note: In Refreshabraille 18 emulation, only the first 18 braille cells are used.

## 17.4 USB

Universal Serial Bus (USB) is a technology that makes connecting devices with hosts easy. It provides some advantages over Bluetooth because it is both faster and charges the Orbit Reader 20 Plus simultaneously.

The Orbit Reader 20 Plus supports three kinds of USB connections (all with the same cable available in the box.)

1. Human Interface Device - Orbit (recommended)
2. Braille - HID
3. Serial
4. Mass Storage (for turning the Orbit Reader 20 Plus's SD card into a drive on your computer)

### 17.4.1 Human Interface Device (HID) – Orbit

### 17.4.3 Serial

When using a screen reader that only supports Serial protocol, follow these steps:

1. Turn on the Orbit Reader 20 Plus. It displays the last read material.
2. Connect the USB cable. "-- Charger connected" is displayed.
3. On the Orbit Reader 20 Plus, press Space + Dots 3 7. "-- Serial USB" is displayed.
4. Install any necessary drivers. See the Orbit Reader 20 Plus Resources page or screen reader manufacturer's support webpages.
5. Configure the screen reader. Refer screen reader section in this document or refer to your screen reader documents.

### 17.4.4 Mass Storage

To use an SD card inserted in the Orbit Reader 20 Plus as a drive on your computer, follow these steps:

1. Turn on the Orbit Reader 20 Plus. It responds with braille from your last activity.
2. Connect the Orbit Reader 20 Plus and your computer using USB cable. "-- Charger connected" is displayed.
3. On the Orbit Reader 20 Plus, press Space + Dots 5 7. "-- Mass Storage mode" is displayed. Depending on your settings, the computer also responds with a notification of a new drive that is now available.
4. Use your PC to read and write files on the new drive.

To switch back to Stand-Alone mode, press Select + Left Arrow. Do not switch back to Stand-Alone mode while file transfers are in progress.

Note: If you have hidden files enabled on your device, you may encounter the following files:

· .BKP-FILEHISTORY - This file contains information of the last read position of the last 100 files that were opened on the device.

· .BKP-RECENTHISTORY - This file contains information required for software to generate the recent file list.

· .Logfile - Log file containing software debug information.

Do not delete these files. You will only see them if you have hidden files enabled.

## 17.5 Buffering Text Input to Remote Devices

If you are typing fast on a braille display, there will be times when the remote device lags behind, slowing down your ability to input text quickly. The Orbit Reader 20 Plus has a Buffer mode that allows you to input text up to 255 characters and send them faster to a remote device, avoiding problems with the speed of input of translated braille.

Note: Buffering text works only when connected over Bluetooth.

To open an input field in the Buffer mode, press ’Select + Down Arrow’. Once open, a cursor indicates that you can start entering text. Press Dot 8 to send the entire block of text to an “edit text field” on the remote device. Note that nothing happens when you send a text with no edit box open. Press Select to cancel the action and exit the Buffer mode, without sending any text.

## 17.6 iOS Devices

You can connect to iOS devices using Bluetooth only.

### 17.6.1 Connecting iOS with Bluetooth

Connecting the Orbit Reader 20 Plus to an iOS device provides both braille feedback and the ability to type and control the device with the Orbit Reader 20 Plus keyboard and directional buttons.

You must set the Orbit Reader 20 Plus to emulate RB18 in the menu.

In default configuration (Just Works), the Orbit Reader 20 Plus is ready to pair with iOS via Bluetooth. Follow these steps to pair with Bluetooth:

1. Turn on Bluetooth. Bluetooth can be turned on in the Menu or by pressing Space + Dots 4 7 on the Orbit Reader 20 Plus.
2. On the iOS device, go to Settings > Accessibility > VoiceOver > Braille unless using a version of iOS prior to 13, then go to Settings > General > Accessibility > VoiceOver > Braille, Look for the name of the unit in the list of possible braille displays. It shows up as Orbit Reader 20 Plus or Refreshabraille18 plus the last four digits of the device serial number.
3. Activate the Orbit Reader 20 Plus device in the list to pair.

Confirm code configuration shows a random number on both the Orbit Reader 20 Plus's braille display and on the host device. To confirm the request, ensure that the numbers match and then press Dot 8 on the Orbit Reader 20 Plus. Then press the Pair button on your iOS device.

Once you pair the unit, iOS starts sending braille to the Orbit Reader 20 Plus, and you can use the Orbit Reader 20 Plus input and navigation keys to control your iOS device.

Note: VoiceOver must be on in order to send braille to the Orbit Reader 20 Plus.

The Orbit Reader 20 Plus can be connected to a Mac in two ways. One is to connect using the USB cable available in the box. The second is to use Bluetooth for a wireless connection.

### 17.7.1 Connecting to a Mac over USB

The simplest way to connect the Orbit Reader 20 Plus to a Mac is to connect using a USB Standard-A to Micro-B cable. Currently, to use the Orbit Reader 20 Plus with the HID protocol you should pick HID from the USB option on the menu. Next, run VoiceOver by pressing the Apple CMD key + F5. Then, attach the small end of the USB cable to the Orbit Reader 20 Plus with the bumps facing down and the big end to Mac. VoiceOver automatically recognizes and starts using the display.

### 17.7.2 Connecting to a Mac over Bluetooth

The default configuration for pairing with Mac through Bluetooth is ‘just-works’. If Bluetooth has been turned off, it can be turned on in the menu or by pressing Space + Dots 4 7 on the Orbit Reader 20 Plus.

If the Orbit Reader 20 Plus is in default connection, follow these steps to pair the device with a Mac:

1. Turn on Bluetooth. Bluetooth can be turned on in the menu or by pressing Space + Dots 4 7 on the Orbit Reader 20 Plus.
2. When VoiceOver is on, open VoiceOver Utility by pressing VO-F8
3. Click the Braille category, click Displays, and then click the Add (+) button
4. Select Orbit Reader 20 Plus in the list. VoiceOver filters the devices it detects to list only the Bluetooth braille displays that are within range of your computer and that appear to match a VoiceOver braille display driver.
5. Activate the Orbit Reader 20 Plus device in the list to pair.

The Confirm code configuration shows a random number on both the Orbit Reader 20 Plus's braille display and on the host device. Follow steps 1 through 3. The Mac shows you a dialog with a security code. To confirm the request, compare the numbers in the Bluetooth dialog on the Mac with the code shown on your display. If they are the same, select ‘Yes’ in the dialog on Mac. If the numbers do not match, select ‘No’ and try the next the Orbit Reader 20 Plus in the list. Pairing requests can be accepted by pressing Dot 8 or rejected by pressing Dot 7 from the Orbit Reader 20 Plus device. The purpose of this procedure is to allow more than one Orbit Reader 20 Plus device to be paired in the same room at the same time without pairing the wrong device.

If the Orbit Reader 20 Plus does not work with VoiceOver, it is possible that you are not using the latest Mac OS. In that case, you have two choices:

1. Put the Orbit Reader 20 Plus in Refreshabraille 18 (RB18) Emulation mode. Then connect it as an RB18
2. Check for updates. We suggest you update to the latest operating system

If the Orbit Reader 20 Plus is not listed, make sure you have turned on Bluetooth in the Menu.

### 17.7.3 Controlling the Orbit Reader 20 Plus from a Mac

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

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

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

## 17.11 Windows PCs

Before connecting the Orbit Reader 20 Plus with a PC, you must first decide how you wish to connect: via Bluetooth or USB. This is a personal choice. USB charges the device as you use it, so it is a good choice when your battery is low. Bluetooth does not use wires, so it is a good choice when you are on the go.

### 17.11.1 Connecting to Windows over USB

If your screen reader does not support HID, switch to the Serial protocol on the Orbit Reader 20 Plus with the hotkey or selecting Serial from the USB option in the menu.

For Windows versions 7 and newer, the serial interface requires the installation of two drivers: one for the USB and one to make the USB port appear like a COM port. The only exception is Windows XP. Because it is Serial only, it can just be plugged in. The second driver is required because many screen reading programs handle braille displays like a serial device. The COM port assignment driver shows the assigned port number used to communicate with the display. Take a note of the COM port number for later use. If you need to look at it later, 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 the Orbit Reader 20 Plus. You need to use that number when you set up your screen reader.

Once the display is connected to the device you wish to use, configure the software to use the Orbit Reader 20 Plus.

### 17.11.2 Connecting to Windows over Bluetooth

When connecting the Orbit Reader 20 Plus with Bluetooth, you must first choose a pairing configuration.

The default configuration is ‘just works’. If the Orbit Reader 20 Plus is in default connection, follow these steps to pair the device:

1. On the PC, perform a Bluetooth search.
2. Select the Orbit Reader 20 Plus from the list of Bluetooth devices.

Confirm code configuration shows a random number on both the Orbit Reader 20 Plus's braille display and on the host device. Follow steps 1 and 2; then, to confirm the request, compare the numbers in the Bluetooth dialog on the Windows PC with the code shown on your display. If they are the same, select ‘Yes’. If the numbers do not match, select ‘No’ and try the next Orbit Reader 20 Plus in the list. Pairing requests can be accepted by pressing Dot 8 or rejected by pressing Dot 7 from the Orbit Reader 20 Plus device. The purpose of this procedure is to allow more than one Orbit Reader 20 Plus device to be paired in the same room at the same time without pairing the wrong device.

The device pairs with the Orbit Reader 20 Plus and an incoming Bluetooth virtual serial port is set up on the PC.

Next, check the Ports list in the Windows Device Manager to find the COM port number assigned to the outgoing Bluetooth serial port. Make a note of this number.

In your screen reader on the PC, set the active Braille display COM port to use as the relevant Bluetooth serial port COM number.

### 17.11.3 Non-Visual Desktop Access (NVDA)

If you have NVDA (version 2017.1 or later) installed on your PC, it automatically recognizes the Orbit Reader 20 Plus. If NVDA is not recognizing the display, go to the NVDA Preferences menu and select Braille Settings from the list. From the braille display drop-down menu, select "Baum/Humanware/APH/Orbit Displays" and click OK.

Note: NVDA works in HID (Orbit) only, not Serial.

NVDA turns ‘On’ braille output when it is configured for the display. To turn ‘Off’ braille support, select "No Braille" from Braille Display options in the Braille Settings menu.
