Orbit Flow 40 does not have an internal battery. It turns on when connected to a powered host through USB and turns off when disconnected.

4.4 Braille Cells and Cursor Routing Buttons

Orbit Flow 40 has 40 eight-dot braille cells. Each cell can display six-dot or eight-dot braille, depending on the screen reader, braille table, and current reading mode.

Dots 7 and 8 are located below dots 3 and 6. These dots may be used for capitalization, cursor indication, attributes, accent marks, or other screen reader-specific information.

Above each braille cell is a cursor routing button. Cursor routing buttons are usually used to move the cursor to the corresponding braille cell position, activate an item, or perform another function assigned by the screen reader.

In this guide, cursor routing buttons are abbreviated as CR. For example:

• CR 1 means the cursor routing button above the first braille cell.

• CR 2 means the cursor routing button above the second braille cell.

• CR 40 means the cursor routing button above the fortieth braille cell.

The exact behavior of cursor routing buttons depends on the screen reader and application being used.

5. Getting Started

Orbit Flow 40 works only as a braille display for a connected host device. It must be connected to a computer, phone, tablet, or other compatible device running a screen reader.

5.1 Power and USB Connection

Orbit Flow 40 connects to a host device using a USB Type-C cable.

The USB connection provides both:

• Power for the Orbit Flow 40.

• Communication between Orbit Flow 40 and the host device.

Orbit Flow 40 does not have an internal battery. It does not support external chargers or power adapters. It operates only while connected to a powered host device through USB. When the USB cable is disconnected, the device turns off immediately.

To connect Orbit Flow 40:

1. Connect the USB Type-C end of the cable to the USB Type-C port on the left side of Orbit Flow 40.

2. Connect the other end of the cable to a powered host device.

3. Start or restart your screen reader if needed.

4. Configure the screen reader to use Orbit Flow 40 or the appropriate HID Braille display option.

5.2 What Appears on the Braille Display

When Orbit Flow 40 is connected to power but no screen reader is active or connected, the display shows device information.

For example:

Orbit Flow 40 V00r01 HID-Braille

This message may include:

• Product name.

• Firmware version.

• Current connection mode.

For example, HID-Braille means the device is using the standard HID Braille protocol. This is the recommended plug-and-play mode for supported screen readers.

When a screen reader connects successfully, the display changes to show the screen reader’s braille output.

5.3 Device Operating Mode

Orbit Flow 40 operates in remote mode only.

Remote mode means that Orbit Flow 40 acts as a braille input and output device for a connected host. The screen reader on the host device controls what is shown on the braille display and how the keys behave.

The main operating protocol for Orbit Flow 40 is HID Braille.

HID Braille is a standard protocol for braille displays. It allows supported screen readers and operating systems to recognize the display as a standard braille device. This makes Orbit Flow 40 easy to connect and use, because it is designed to work as a plug-and-play braille display.

The following screen readers and platforms support HID Braille:

• JAWS for Windows.

• NVDA for Windows.

• VoiceOver on macOS, iOS, and iPadOS.

• TalkBack on Android.

Orbit Flow 40 also includes HID Orbit emulation. HID Orbit makes the device appear as an Orbit Reader 40. This mode is intended only for situations where a screen reader or host system does not support HID Braille correctly, or where Orbit Reader 40 emulation is specifically required.

For most users, HID Braille is the recommended mode.
