== My Fine Offset console says the memory is nearly full - how do I clear it? ==
You don't need to, and it's much safer if you don't; clearing the memory could lead to a loss of data. The console will automatically start re-using the oldest memory locations.
== How do I get my Davis station with USB working with Cumulus? ==
Cumulus cannot drive the station in USB mode, you must install 'virtual serial port' drivers, and configure Cumulus to use the virtual serial port.
You should first make sure that you can use the station with Weatherlink, in serial mode. If you have not already installed the Weatherlink software, install the version which came with your weather station. You should then upgrade to the latest version of Weatherlink; you can download the update from the Davis web site, [http://www.davisnet.com/support/weather/downloads/software_sftwr.asp here].
You now need to install the 'CP210X USB to Serial Converter'. You may find a link on your Start menu under 'Weatherlink'. Alternatively, you should find it in the folder where Weatherlink was installed, under 'Support' then 'Utilities'. Davis also make it available on their web site, [http://www.davisnet.com/support/weather/downloads/software_driver.asp here]
It's a good idea to then update the driver to the latest version from the Silicon Labs web site, particularly if you use Windows 7. You can download it [http://www.silabs.com/products/mcu/pages/usbtouartbridgevcpdrivers.aspx here] - click on 'VCP driver kit' under 'Download for Windows XP/Server 2003/Vista/7' to begin the download. Run the executable once it's downloaded.
At this point, it's best to restart your computer.
You should now run Weatherlink, and attempt to connect to the weather station '''in serial mode'''. Weatherlink should find the appropriate COM port number automatically. If not, you can find it under 'Ports (COM & LPT)' in the Windows device manager. Look for the port called 'USB Serial Port (COMn)', where 'n' is a number. That's the number of the port you need to use in Weatherlink. If you cannot get Weatherlink to work using this virtual COM port, it is unlikely that you will be able to get Cumulus to work either, so either contact Davis support, explaining that you are trying to use the virtual serial port drivers because you want to run third-party software, or ask in the Cumulus forum, someone may be able to advise.
Once you have Weatherlink connected and working via the virtual serial port, '''close it down''', and start Cumulus.
In the station settings in Cumulus, select the appropriate station type for your station; under 'VP Type' select '''Serial'''; in the serial port section enter the COM port number that you found earlier. You may need to restart Cumulus at this point. It will then start displaying live data. Note that the it deliberately does not download any historical logger data from before the current point in time. When you run it subsequently, it will download logger data to catch up if necessary from when you last ran it, but never from earlier than when you first ran it.
