TROUBLESHOOTING GUIDE

Recalculate THSW Index - Vantage Pro Only

WeatherLink 5.3 and later supports a new derived data parameter, the Tempera-

ture Humidity Sun Wind (THSW) Index. If you have a solar radiation sensor, you

can have this value calculated for existing data by selecting the “Recalculate

THSW Index” command in the Browse Menu, which is displayed when the

Browse window is open.

Note: Be sure to verify that the latitude and longitude settings and daylight savings time set-

tings are correct before using this command.

Troubleshooting Guide

The following section answers some of the most commonly asked questions about

WeatherLink

. Please consult this guide and WeatherLink Help before contacting

Technical Support (see page 17).

Communications Problems

? Why can’t the WeatherLink software communicate with the data logger and sta-

tion?

If you are having trouble establishing communication between the weather

station and WeatherLink, start by checking the weather station’s own diagnos-

tics. Remove all power to the weather station and then restart it by restoring

power (with the data logger still attached).

Note: Vantage Pro Only - The data logger uses non-volatile memory, so you won’t

lose any data you’ve already recorded. However, make sure to put the con-

sole in Setup Mode by pressing and holding the [DONE] key, then pressing

the [-] key before removing the batteries. This ensures the station will not try

to write any data as the power goes off.

• You should hear three beeps, each of which occurs when the weather

station passes one of its diagnostic tests. Each beep follows the

previous after about one second. The first beep tells you the processor

is running. The second beep will be for the logger (if installed) and the

third beep is for the display. If you do not hear one or more of these

beeps, contact Davis Instruments at 510-732-7814. (You’ll only hear two

beeps if you don’t have the data logger installed.)

• If you hear all three beeps, See “Finding the Correct Serial Port” on

page 11 for instructions on checking your standard serial ports. If this

identifies a serial port other than the one you selected in station setup,

try connecting to the data logger again.

• Vantage Pro Only - make sure you are using the blue serial port

adapter supplied with WeatherLink #6510C. The black Davis serial

adapters will not work.

• If you have a Monitor, Wizard or Perception station, make sure you are

using the black serial port adapter supplied with WeatherLink #7862.

The blue Davis serial adapters will not work.
