The Orbit Reader 20 uses the SD Card for storage of files for reading and editing.
SD CARD AND FILE SYSTEM RELATED QUESTIONS:
SD cards should be formatted with FAT32 file system only.
The Orbit Reader 20 supports SD cards with memory capacity ranging from 4 to 32 GB.
The maximum length allowed for a file name and path is 255 characters. This means that a user can have files with long file names and short directory path or short file names with longer directory paths.
When a file is created or edited, the Orbit Reader 20 applies a fixed date and time, i.e. “1-Jan-2017 00:00:00”.
There are no Orbit Reader-specific limitations to the number of files that can be stored in a single directory. However, the file sorting function is limited to the first 250 files found on an SD card.
The txt, .brl and .brf file formats are supported in Local Mode.
A maximum of 100 files within the same directory can be marked for cut, copy or delete operations.
Cut, copy and delete operations can be performed only on empty folders. If the user attempts to perform these operations on a non-empty folder, then the system generates an error message.
Text files are encoded with ANSI, UNICODE-LE16, UNICODE-BE16, UTF8 format only. Other encoding formats are not supported.
The system is unable to identify the files deleted from outside the device environment. The device will display the message “File not found” for that particular file when reached during navigation.
The maximum number of files shown in the recent file list is 20.
This error message indicates an internal error with the SD card, such as corrupt memory regions or a damaged card adapter.
READER AND EDITOR RELATED QUESTIONS
A maximum of 5KB (approximately 5000 characters) of file content can be copied at a time. If the user attempts to mark data above this limit, then an error message is generated.
The maximum number of bookmarks that can be set in a single file is 100. If a user attempts to set more bookmarks than the allowed limit, then an error message is generated.
The Menu text formatting options are applicable for Reader only. The Editor always shows non-formatted characters.
The Cut/Copy block operations can be performed only in Editor. To perform these operations in Reader, the user should first open the current file in Editor and perform the desired operation. Closing the editor will take the user back to the reader.
It is highly recommended not to remove the SD card while editing. Editor applications will shut down and edited data will be lost if the SD card is removed while the Editor is running.
A file is automatically saved on exiting the Editor. A file is also automatically saved while editing or navigating 1KB data within the file.
BLUETOOTH RELATED QUESTIONS
Pairing requests are accepted automatically if the pairing method is” Just Works”. If the pairing mode is set to “Confirm Code”, then the Orbit Reader 20 will not respond.
Four Bluetooth devices can be connected to the Orbit Reader 20. However, only one Bluetooth device will be active at a time. In order to switch between connected devices, first put the current connected host on standby (screen lock the phone) and then wake up the other host from standby (unlock the phone). The host will then connect to the Orbit Reader 20 automatically, provided it was paired already.
The Orbit Reader 20 device puts Bluetooth connection on highest priority. Whenever there is any activity on Bluetooth channel, the display is taken over by messages from the Bluetooth. If you need to work in local mode, put the Bluetooth device on standby when you are working on mobile or turn off Bluetooth from the preference menu when you are working on a PC or a Laptop.
The Orbit Reader 20 keys cannot be used to wake up a mobile from standby, but can be used to enter a password to unlock the screen for iPhones.
Android phones with Google’s BrailleBack does not support this functionality.
This behavior is controlled by the screen reader applications running on the mobile device. Below are our observations.
For iPhones, there are no messages shown for an incoming call. For message notifications, it connects upon receiving notifications however doesn’t display notification contents. The display shows the content of the screen which is usually the clock.
For Android phones, upon receiving call, device displays the content of the screen. Exact content may vary among different manufacturers of the mobile devices. It may or may not display the number for incoming call. The device doesn’t display anything for incoming message notifications.
This depends on the screen reader application running on your mobile phone. Our observations are as follows:
For iPhones, no messages are shown for incoming calls. For message notifications, it does connect on receiving a notification, but the contents are not displayed. The display shows contents of the screen which is usually the clock.
For Android phones, on receiving a call, the device displays contents of the screen. The exact content may vary depending on the make of the mobile phone. The device may or may not display the number for an incoming call. The device does not display anything for incoming message notifications.
Note that iOS is paired through settings->General->Accessibility->VoiceOver->Braille->Choose A Braille Display and not through Settings->Bluetooth->Devices.
REMOTE MODE RELATED QUESTIONS
The Orbit Reader 20 works as an 18-cell device when it is emulated as Refreshabraille 18. The last two cells always remain blank.
The Emulation mode can be changed only when there is no active screen reader connection. If the user attempts to change emulation during an active screen reader connection, the system will give an error message.
The Orbit Reader 20 resumes connection with previously connected device on being powered on. If the connection was lost when the device was ‘on’, then the connection needs to be re-established manually. There are some simple ways to do his. They are as follows:
a. Lock the screen of the phone and unlock.
b. For Android, go to Settings->Accessibility->Brailleback->Setting and click on the tatus or turn off the Brailleback and turn it on again.
c. For Ios, go to Settings->General->Accessibility->Voiceover-> Braille and double click on the name of the braille device, or turn off the voice over and turn it on again.
d. If nothing works, unpair the braille device and pair it back.
When the Emulation mode is changed, the “connected device list” does not show that change. However, the current session works fine without any issues. Unpairing the Orbit Reader 20 and pairing it again with the host will show the changed name in the “connected device list”.
If the android device is in sleep mode, then there is a chance that it may connect to the Orbit Reader 20 in the wrong emulation mode on waking up. Here, the user can
disconnect (forget) the device and pair it again.
The current active connection (USB or Bluetooth) will be reset and re-initialized..

You might have enabled a status cell on the right-hand side. You can turn it off in Braille settings.
The following issues have been noted while working with Android-
a. Automatic switching does not happen while working with Android Devices. The Orbit Reader 20 has a feature wherein, if USB and Bluetooth both are active at the same time, Bluetooth takes over the connection and in the event of the phone being locked, the mode is switched to active USB mode automatically. This automatic switching does not happen for Android devices.
b. When you type text messages on the Android device, corresponding text does not get displayed on the device.
c. It is not possible to enter the ‘screen unlock’ password of the phone from the Braille keypad of the device.
