1 Area of application
The evaluation kits were designed to show you the
main function and output of the energy harvesting
wireless switch.
The components provided are for testing purposes
and not suitable for using in a serial product, con-
tinuous operation or permanent connection to
other units.

1.1 Comfort evaluation kit
The Comfort evaluation kit receiver class 3 was
developed for convenient operation in a compact
design.
As only a small antenna is fitted due to its compact
design, the range is less than with an external
antenna.
The switch signals are displayed on the receiver
stick with LEDs. You can also see the strength of
the signals via software on a computer.

1.2 Engineer evaluation kit
The engineer evaluation kit receiver class 2 is
designed for optimum output and consists of
several interfaces for the development
environment. It may only be operated by those with
electrical engineering expertise.
To gain direct access to the interfaces, the receiver
consists of a large circuit board without housing.
Several antennas can be connected to the SMA

You can also see the strength of the signals via the
software on a computer. These can be exported for
measuring.
2 Product description
2.1 Wireless switch
The switch contains a generator which converts the
mechanical energy of the probe into electrical
energy. The energy supplies the wireless
electronics and data is transmitted the with
868 MHz (Europe) or 915 MHz (US version).
2.2 Generator model
To show the small size of this part, the evaluation
kit contains a functionless volume model of the
generator.

2.3 Receiver
The radio signal is received by the antenna. The
electronics interpret the data and transmit the
information to the hardware and software
interfaces. The information is displayed via LEDs
and the software.
See also: 7 "Engineer receiver interfaces".
2.4 Software
The software on the computer displays the
following data:
You can save up to 10 000 data sets. The data can
be deleted using the "Clear" button and saved as
*.txt files using the "Export" button. The

communication with individual switches and the
relay function can be deactivated.
2.5 Antennas
The Engineer evaluation kit contains 2 exchange-
able antennas:
• SMD antenna circuit board with SMA connector
• SMA dipole antenna
2.6 CD
The CD contains demonstration software, CAD files
with the dimensions and these operating instruc-
tions.

3 Installing the USB driver
System requirements:
Windows XP, Vista or 7, USB 2.0 connection.
1 Copy the "Cherry_EHS-RF_Software" folder from
the CD onto your computer.
2 Connect the receiver.
•Comfort evaluation kit:
Plug the receiver stick into the computer so that
the components (LEDs) can be seen on the cir-
cuit board. Use a USB hub or an extension cable
if necessary.
•Engineer evaluation kit:
Connect the receiver circuit board to the com-
puter using the USB cable provided.
The yellow LED flashes on the receiver.
The device driver installation prompts you to
install the driver software. The drivers for 32- and
64-bit variants are located in the "Cherry_EHS-
RF_Software/Driver" folder.
3 Follow the instructions in the installation wiz-
ard. If problems arise, you will find detailed video
instructions on the CD.
The yellow LED lights up on the receiver.
