The communications channels/ports are located in the recess at the back of the
device on the right, approximately 2cm deep. On the far left is the round socket for
the serial port; in the middle the square socket for the USB port (mini-USB port) and
on the far right the mains adapter socket (5 volt).
The non slip plastics upper surface is an ideal support for the PC keyboard.
The cover on both ends can be unscrewed to allow additional modules to be
connected, thus allowing VarioPro to be adapted to suit your needs. The modules
can be connected to the left or right of VarioPro. Several can be connected together
(see Chapter 10).

VarioPro Braille displays are powered from the PC with a USB cable connection.

level of power: insert the adapter’s small plug into the right-hand socket on the back
of the device and then plug the adapter into a mains outlet. Please use only the
original mains adapter for VarioPro to avoid possible damage.
NB!!
Under no circumstances should the adapter from an older Vario40 or Vario80 be
used, as they work at a much higher voltage which will almost certainly damage your
VarioPro.
