Configuring WXNOW.TXT Ports

Some weather stations do not publish their internal communications protocols, and require that applications wishing to consume weather data use a proprietary program that converts the weather station's data to a text file containing the current weather information. YAAC is capable of periodically polling such a text file using one of the WXNOW file formats, generated by such programs as:

• Cumulus
• Davis Weather-Link data logger
• Weathercat

To use a weather station with this interface, click the Add button on the Configure Ports tab. The port editing dialog will appear. Set the port type to WXNOW.TXT.

The other parameters you will need to specify are:

• the complete path name of the WXNOW.TXT file, including the path to the directory containing the file.
• the format of the WXNOW.TXT file, either 2-line Cumulus format or 1-line Weathercat format.
• the time period between checks of the file for updated weather data.
• The make and model of weather station you are using. If the model you are using is not on the APRS standard list, you can type it in instead of picking from the standards.

Once you have the settings the way you want them, click OK.

You can check how well your weather station is performing by selecting the menu choice View->Show Weather Status.
