Before connecting Orbit Reader with a PC, you must first decide how you
wish to connect: Bluetooth or USB. This is a personal preference. 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.
Connecting Windows with USB
Normally, modern screen readers support the HID protocol, which means
you do not have to install any drivers to use Orbit Reader with a PC screen
reader. If your screen reader does not support HID, switch to Serial mode on
the Orbit Reader with the hot key or selecting Serial from the USB option in
the menu.
For Windows versions 7 and up, 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 now for later use. 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 Orbit Reader 20. You need to use that number
when you set up your screen reader.
