Storing The Solar-Powered Outdoor Sensors; Commissioning The Software - La Crosse Technology WS-2010 Software Manual

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. The sensor can thus remain stored, e.g. in its
packing, for several years.
Following a longer period in storage, it is recommended to recharge the integrat-
ed battery before starting the system up. To do this, expose the solar cell, which
is connected to the battery system even when deactivated, to sunlight for sever-
al hours.

Commissioning the Software

After activating the operating and evaluation software, the interface is connect-
ed to the COM port intended. The standard setting is connection to the 1st serial
interface (COM 1). If necessary, select a different interface by selecting the menu
"Interface", submenu "Properties" and option "Interface".
The standard version of the weather station (PC interface) can support up to 16
temperature/humidity sensors which are automatically detected when the ad-
dresses are set correctly. Detecting the number of sensors simultaneously de-
termines the number of measured values which can be stored in the radio inter-
face. The memory should be read out when full at the latest so that no data is
lost. When 16 sensors are used, the memory requirements are increased corre-
spondingly so that fewer values can be stored in the same time period.
The number of measured values which can be stored is also affected by the
Interval selected. The interval, i.e. the time period at which the weather data is
recorded, can be set between 1 minute and 60 minutes. The standard setting is
recording every 5 minutes.
The following table indicates the connection between the number of sensors
supported, the selected interval and the maximum storage period, without meas-
ured values being lost. Each dataset requires 56 or 30 bytes. The radio interface
has a memory capacity of 32 kbyte.
