you are ready to resume using Bluetooth, either turn it back on from the Orbit
Reader 20 menu or use the hotkey Space + Dots 4 7 from Stand-Alone mode on
the Orbit Reader 20. (You can always return to Stand-Alone mode by pressing
Left Arrow on Orbit Reader 20.)
17.4 Connect to Multiple Hosts
It is possible to pair Orbit Reader 20 with more than one device. For example,
you may wish to pair it with both your phone and tablet, so whichever device you
use offers a braille interface.
To more easily use Bluetooth with multiple devices, the screen reader on each of
the devices should be set to the same emulation. In other words, if you have an
iPad with a version prior to 10.2, it does not recognize Orbit Reader 20.
Therefore, you should set all Emulation modes to be compatible with the older
version. If all the hosts you are using support Orbit Reader 20 directly, turn
Emulation mode off. If any of them do not support Orbit Reader 20, set the
Emulation mode for all of them to RB18.
While it is possible to pair to 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 Orbit Reader 20 is set to be used with multiple devices.
The first device appears to work, but it does not function correctly, because it still
uses Orbit Reader 20 commands instead of Refreshabraille commands, which
Orbit Reader 20 expects when Emulation mode is set to RB18.
When connecting to older host devices that do not support Orbit Reader 20 to
ensure proper functioning of commands between Orbit Reader 20 and host
devices, Set Orbit Reader to emulate RB18.
Note: In Refreshabraille 18 emulation, only the first 18 braille cells are used.
17.5 USB Connection Options
Universal Serial Bus (USB) is a technology that makes connecting devices and
hosts easy. It provides some advantages over Bluetooth, because it is both faster
and charges your Orbit Reader 20 simultaneously.
Orbit Reader 20 supports four kinds of USB connections (all with the same cable
included in the box.)
1. Human Interface Device - Orbit (recommended)
2. Braille - HID
3. Serial
4. Mass Storage (for turning Orbit Reader 20's SD card into a drive on your
computer)
