Your serial port uses a non-standard device name.
WeatherLink recognizes serial ports named COM1 through COM10 only.
To use a modem, you must specify the underlying COM port on your PC.
To find out which port the modem's connected to, you can look in Win-
dows' System Properties > Device Manager > "modem name" Properties
> Modem > Port, where "modem name" is the name of the modem you
have installed.
Your serial port is defective.
The loopback connector or the WeatherLink adapter plug is bad.

? The barometer graph on the Bulletin does not "fill in" completely.
When you first load the bulletin, the barometer graph will only fill in com-
pletely when you have data in your database for the last six hours. Make sure
of the following:
There is data in your database for the span of the barometer graph.
The time and date of the stored barometer data is correct in your database.
The time and date on the PC is correct.
The time and date on the weather station are correct.
? I have duplicate records in my database. Why?
If you do not download from the data logger prior to changing the weather
station's time and date (for a Daylight Savings time change, for example), you
may get duplicate records. Make sure to download before setting time and
date. In addition, you should be aware that the midnight records are dupli-
cated so they appear in each consecutive day. For example, a midnight record
would appear at the end of the data for November 22 and at the start of the
data for November 23. Using the record editor to change the record in one day
does not change the record in the other day.
Note: Do not delete the duplicate midnight records; it may affect your rain database or NOAA
monthly summary.
? No wind direction reading (or dashes instead of a reading) appears in my database.
Be aware that if there is no wind speed when the direction is being sampled,
wind direction is not recorded. During intervals with very little wind speed,
no direction may be recorded.
Note: Since high wind speed is sampled more often, it is possible to have a high wind speed
but no wind speed or direction.
