Recalculate THSW Index
WeatherLink 5.3 and later support a new derived data parameter, the Tempera-
ture Humidity Sun Wind (THSW) Index. If your station contains a solar radia-
tion sensor, this value can be calculated for existing data by selecting
Recalculate THSW Index
in the
Browse
Menu, which is displayed when the
Browse window is open.
Note: Be sure to verify that the latitude and longitude settings and daylight savings time settings
are correct before using this command.
Updating USB Drivers
WeatherLink 5.6 and later versions includes a newer version of the USB driv-
ers that have been installed for previous versions of the software.
Note: You must verify the USB driver currently installed on your computer and update the driver
if you have a previous USB version of WeatherLink.
1. Connect the console or Weather Envoy to your computer via the USB data
logger.
2. Open the
Device Manager
on your computer.
3. Select the
Universal Serial Bus
controller node from the device tree. An
entry “CP2101 USB Composite Device” or “CP2101x USB Composite
Device” should appear at the top of the list. If it does not, disconnect and
reconnect the USB connection.
4. Double click this entry. The
Properties
dialog box displays.
5. Click the
Driver
tab. The current driver’s version number and information
displays.
6. If the Driver Date field is 12/16/2004 and the Driver Version field is
4.28.0.2700, the correct version of the USB driver is installed and no
update is needed. If the Data field listed is earlier than this date or if the
Driver Version is not the number described, you must uninstall the driver
and install the new version of the USB driver.
