Page 8: General Information
General Information The radio weather station represents a highly sophisticated, easy to use, univer- sal weather measuring system which can record, evaluate and display the data from up to 16 external radio sensors for temperature and humidity, a sensor for wind and another for rainfall. -
Page 9: System Requirements
System Requirements The operating and evaluation software can basically be run on any PC using Windows 95/98 or Windows NT. However, to enable fast processing, it is recom- mended implementing at least a 486 DX with a frequency of 66 MHz. When Windows 95/98 is used, the PC should have at least 16 Mbyte RAM to ensure processing can be completed quickly. -
Page 10: Installation
Installation The operating and evaluation software for the weather station is installed by activating the "Install“ installation program provided on the program disk. This can be done, for example, by using the "Run“ command in the Windows 95/98/ NT Start menu. The required target directory can be selected during the installation process. -

Page 16: Preparations
Preparations This section describes the working steps and settings necessary in order to start the sensors and weather station as well as the operating and evaluation soft- ware. The outdoor sensors for measuring wind speed, rainfall, outdoor temperature and relative humidity are equipped with a solar cell for power supply and a lithi- um backup battery for periods of darkness and bad weather. -
Page 17: Preparing The Pc Interface
Preparing the PC Interface Preparation of the PC interface consists purely of inserting two AA alkaline batteries in the battery compartment on the rear side of the unit. Only use high quality alkali-manganese batteries. The PC interface can- not be operated without batteries. The PC interface should only be put into operation after all the connected sensors have been in operation for more than ten minutes! During the initialization phase, no communication may be established between... -
Page 18: Commissioning Measured Value Transmitter
Commissioning Measured Value Transmitter The weather station sensor concept is based on two groups of sensors. The basic requirement to operate the weather station is the indoor radio sensor with barometric atmospheric pressure. This sensor transmits a fixed data telegram which defines the display of the temperature and relative humidity in the display area for indoor values. -

Page 20: Adressing The Radio Sensors
Fill the recess with a little water and then align the lower part of the housing according to the spirit level principle. After marking the installation position ex- actly, drain off the water. Ensure the solar cell faces south. The short side of the integrated spirit level must point north. -
Page 21: Indoor Radio Sensor Without Air Pressure
Indoor radio sensor without air pressure The indoor radio sensor without air pressure corresponds to the indoor sensor with air pressure with regard to operation and function. However, it only contains a temperature and humidity sensor, but no air pressure sensor. This sensor can be freely addressed and assigned a name. -
Page 22: Storing The Solar-Powered Outdoor Sensors
Storing the Solar-Powered Outdoor Sensors The outdoor sensors receive their operating power supply from a solar cell. En- ergy is also stored in a integrated battery which assumes power supply during periods of darkness and bad light. If such a sensor remains out of operation for a longer period and receives no light, there is no risk to the internal battery if the magnets, inserted to activate the operating voltage, are removed. - Page 23 The number of sensors to be supported can be modified using menu "Interface“, submenu "Properties“, option "Initialize“. Note: If these settings are changed, the radio interface is re-initialized. All the weather data stored up to then is lost. In addition, the radio interface cannot send any data to the PC for approx.

Appendix B Special Terms Air pressure history - storage and graphical display of the air pressure over the last 72 hours. This can be used to determine conclusions related to the general weather development. The graphical representation appears in the weather dis- play. -
Page 53: Appendix C Eliminating Faults
Appendix C Eliminating Faults If transmission is not received from a sensor for 36 hours, its value disappears from the display. At regular intervals (17 hours) the PC interface polls all the sensors during a six minute period in case synchronization between sensor and PC interface has been temporarily affected by transmission path interference. - Page 54 A newly added radio sensor (e.g. following a change of batteries) is auto- matically accepted by the system and the related data is displayed. Faults are often restricted to limited periods (radio communication) or can be easily eliminated. If a unit, e.g. radio headphones, remote babysitter, etc is oper- ated your house or a neighbor’s at 433 MHz, the period of activity is normally limited.
