Weather Downloads: Firmware

Click on a title to see more details or to download.

Our Firmware is downloadable at no charge, but requires use of our Vantage Pro Updater for Vantage Pro2 or Vantage Pro Updater for Original Vantage Pro, which are available for purchase through our secure e-commerce system.

If your Vantage Pro2 Console Firmware is dated 28-Nov-05 or later, you may update your console with the Direct PC Install file. This is a stand alone application that will update your console firmware directly through the WeatherLink data logger connected to your PC. (WeatherLink for Vantage Pro2 (#6510SER, 6510USB, 6540, 6544, 6550 or 6560) is required to use the Direct PC Install file.) DO NOT USE the Direct to PC Install file if your Vantage Pro2 firmware revision is dated before November 28, 2005.

WeatherLink for Mac OSX (#6520) does not support Direct PC Install files. To update your console, use a Vantage Pro2 Updater.
