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, continuous operation or permanent connection to other units.
1.1 Comfort evaluation kit Volume model generator Wireless switch Receiver stick 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 USB cable Wireless switch Volume model Receiver circuit board generator SMD antenna Dipol antenna 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.
connection on the circuit board. See also: 7 "Engineer receiver interfaces". 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.
2.3 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.
communication with individual switches and the relay function can be deactivated. 2.5 Antennas The Engineer evaluation kit contains 2 exchangeable 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 instructions.
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 circuit board. Use a USB hub or an extension cable if necessary. • Engineer evaluation kit: Connect the receiver circuit board to the computer using the USB cable provided.
4 Press and hold down the button on the wireless switch. The green LED lights up. 5 Release the button again on the wireless switch. The blue LED lights up. 4 Installing software Requirement: The receiver is connected and the USB driver is installed (see 3 "Installing the USB driver"). The "Cherry_EHS-RF_Software" folder is on your computer. 1 Link the "RadioMonitor.exe" file on your desktop for later access. 2 Start the link to "RadioMonitor.exe".
4 Press the wireless switch. When you have selected the COM port of the receiver, the switch position is shown on the switch diagram. The "Next >" button is active. • If the button is not active: Repeat the procedure by selecting another COM port from the list until you have found the connection for the receiver. 5 Click on the Next >button. The "RadioMonitor" window appears. 6 Press the switch.
5 Troubleshooting • The yellow LED on the receiver is not flashing: – Use another USB port on the computer/laptop. • The reception is poor: – Remove any metal objects from the transmission area. – Do not place transmitters and receivers directly on reflecting objects or walls. – Switch off any possible sources of radio interference, such as electrical appliances or machines. – Adjust the position of the antenna. – Shorten the distance between transmitter and receiver.
