If you're talking about the Carterlake/WD/AJAX/PHP templates, there are three files updated by Weather Display for text-based weather data (and a series of graphic files).
The two text files (testtags.php and trends-inc.html ) are to be updated by WD every 5 minutes or so.
The clientraw.txt file (used for the AJAX updates) should be sent every 5 seconds or so by WD.
If you are talking about the Carterlake/WD/AJAX/HTML templates, then the wx.html ... wx9.html are updated every 5 minutes or so, and the clientraw.txt file should be sent every 5 seconds or so.
Best regards,
Ken
