2.3.2 USB Host Ports.
The three ports on the left side of the rear edge are the USB host ports. They are lined up one next
to the other. USB host ports on the BrailleNote QT allow you to use the BrailleNote QT with a
range of USB-compatible devices including:
External drives,
External modem,
USB memory drives,
Some USB printers, and
An external memory card reader.
Each of the three ports has a power supply of 500 milliamps. Make sure that a device plugged into a
port does not require more than this.
The USB host ports can also be used with the included USB serial adapter and an appropriate nul
modem serial cable to emboss using the serial port of an embosser or work in Braille terminal mode
using a USB host port on your computer.
2.3.3 Audio Sockets.
On the left side of the unit, there is a microphone input socket, an audio output socket and a record
button.
The microphone input socket takes a high impedance electret microphone with a 3.5mm plug. There
is also a built in microphone.
The audio output socket is stereo and works with most head or earphones with a 3.5mm plug. It will
also connect to a set of mini speakers, as used with a PC. Remember that these will also need to be
plugged in to a wall socket.
2.4 Secure Digital Cards.
Near the middle of the back edge, to the right of the USB host ports, there is a card slot for Secure
Digital cards, also known as SD cards. These cards are only 32mm x 24mm x 2mm big i.e. less than
a quarter of the size of a CompactFlash card, and yet can store several gigabytes of information.
The SD card slot supports up to 2 gigabytes SD cards and 4 to 32 gigabytes SDHC cards of all
classes. For up to date information on the latest developments, check out our website;

The BrailleNote QT uses SD cards for memory only. It does not support SD accessories such as
wireless or Bluetooth cards.
