Lexingtonwx anemometer guide A detailed repair guide to the Davis 6410 anemometer as used in the VP1 and VP2 stations. Note that this guide has not been updated to cover the version of 6410 anemometer manufactured since 2013, which uses a solid-state magnetic switch in place of the original reed switch and is of a different detailed construction; but the broad principles of operation should still apply.
Davis logger API Full details of the programming interface for the Davis Weatherlink loggers (and applicable to all Vue, VP1 and VP2 stations) is available in a document called the ‘Serial Tech Ref’ or Communications Reference, which is downloadable from the link shown. Note that the interface has many available commands and is binary in nature (ie weather data as simple text strings is not available from most of the loggers). But once the binary format of the data output is understood, communications can be set up from newly coded programs using only a very few of the available commands.
Davis Message Protocol ‘Hacking’ Various (largely successful) attempts have been made by interested amateurs to reverse engineer the communications protocol used to transfer message packets between ISS and console. (ie as distinct from the API between logger and computer, which is fully and publicly disclosed in the preceding topic; whereas Davis have never publicly commented on the ISS/console protocol at all.) Several users have collaborated to build up the overall picture and the link given will provide a way into this topic for anyone who is curious.
