A Mini DIN cable to 2 3.5mm jacks is available for connection to this device
Interfacing to an environmental control unit and a communication aid
.
To interface to more than 2 external devices it is necessary to operate both of
them in a 1 or 2 switch mode as per “Devices with 3.5mm jack switch inputs”
described above. Use forward/back deflections of the joystick for one device and
left/right deflections for the other. An interface cable for this kind of setup is
available on request. It is important to note however that as most modern
communication aids have a built in environmental control unit, or the option of it,
this type of setup is rarely required.
Interfacing to DynaVox communication aid with switch inputs
.
The switch inputs of a DynaVox are peculiar in that they can not share a
common signal. A special interface cable is required whose pin-out is described
below and the Genie joystick parameter “External Device” must be set to “2”.
See Section 2 Chapter 4 for details on adjusting Genie joystick parameters.

A Mini DIN cable to 2 3.5mm jacks is available for connection to this device.
Note that for modern devices with a USB port the USB interface is a better
solution, see below.
Interfacing to the USB port on an “on-chair” computer or communication
device
A USB interface cable is now available. This allows the Genie to be connected
to the USB port of an “on-chair” computer or communication device. The cable
connects from the Genie switch output port to the USB port of the external
device. The cable has electronics built in which “fool” the computer or
communication device into thinking that a standard USB mouse is connected.
When external access is selected the joystick on the Genie is used to move the
mouse pointer and button 1 makes left click selections. Mouse movements are
non-proportional.
