Chapter 1

Welcome to Vantage Pro2TM

Welcome to your Vantage Pro2 Weather Station console. The console displays and records your station’s weather data, provides graph and alarm functions, and interfaces to a computer using our optional WeatherLink® software.

Vantage Pro2 stations are available in two basic versions: cabled and wireless. A cabled Vantage Pro2 station transmits outside sensor data from the Integrated Sensor Suite (ISS) to the console using a straight-through four-conductor cable. A wireless Vantage Pro2 station transmits outside sensor data from the ISS to the console via a low-power radio.

Note:

Wireless consoles can also collect data from optional Vantage Pro2 sensors or a

Davis Vantage Vue ISS, and can also retransmit data to other Vantage Pro2 or Van-

tage Vue consoles or a Davis Weather Envoy. You can have an unlimited number of

consoles - one in each room!

The Vantage Pro2 Quick Reference Guide included with your station provides an easy to use reference for most console functions.

Console Features

Keyboard & Display

The keyboard lets you view current and historical data, set and clear alarms, change station models, enter calibration numbers, set up and view graphs, select sensors, and read the forecast. The keyboard consists of 12 command keys located next to the screen display and four navigation keys located below the command keys.

A weather variable or console command is printed on each command key. Just press a key to select the variable or function printed on that key.

Each command key also has a secondary function which is printed above the key on the console case. To select the secondary function, press and release 2ND (on the front of the console, upper right corner) and then immediately press the key for that function.

After pressing 2ND, the 2ND icon displays above the barometer reading on the screen

for three seconds. All secondary key functions are enabled during this time. Keys

resume normal operation after the icon disappears.

The+ and - navigation keys, along with < and > navigation keys are used

+

to select command options, adjust values, and to provide additional func-

<

Chapter 2

Installing the Console

The Vantage Pro2 console is designed to give extremely accurate readings. As with any precision instrument, use care in its assembly and handling. Although installing the console is relatively simple, following the steps outlined in this chapter and assembling the Vantage Pro2 correctly from the start will help ensure that you enjoy all of its features with a minimum of time and effort.

Powering the Console

Cabled Vantage Pro2 Stations

Cabled Vantage Pro2 consoles supply power to the Integrated Sensor Suite (ISS) through the console cable. Because of the added power consumption of the ISS, the cabled console requires an AC power adapter used as the main power supply. The console batteries provide backup power for up to four to six weeks.

Wireless Vantage Pro2 Stations

Wireless Vantage Pro2 consoles do not require the use of an AC adapter. You may use the included adapter if you wish, but the three C-cell batteries should power a wireless console for up to nine months.

Note:

When using an AC Power adapter, be sure to use the power adapter supplied with

your Vantage Pro2 Console. Your console may be damaged by connecting the

wrong power adapter. The console does not recharge the batteries. Because of this,

and because NiCad batteries do not power the console as long as alkaline batteries,

use alkaline batteries in the console.

Installing the AC Power Adapter

1.Remove the battery cover located on the back of the console by pressing down on the two latches at the top of the cover.

2.Find the power jack located on the bottom of the console case.

Power Plug

Wrap Cord Around Pins

3.Insert the power adapter plug into the console power jack, then plug the other end of the adapter into an appropriate power outlet.

Installing Batteries

4.Check to make sure the console runs through a brief self-test procedure successfully. On power up, the console displays all the LCD segments and beeps twice. A message displays in the ticker banner at the bottom of the console, followed by the first screen that displays during Setup Mode. Press and hold DONE to skip the message and enter into Setup Mode.

Setup Mode guides you through steps required to configure the station. See “Setup Mode” on page 9 for more information.

Installing Batteries

1.Remove the battery cover located on the back of the console by pressing down on the two latches at the top of the cover.

2.Insert three C batteries into the battery channel, negative (or flat) terminal first.

3.Replace the battery cover.

Connecting Cabled Stations

Cabled Vantage Pro2 stations come with 100 feet (30m) of cable. This cable is used for connecting the console to the ISS. Maximum cable length from ISS to the console using Davis Instruments cables is 1000 feet. To connect the console to the ISS:

1.Firmly insert the console end of the straight-through four-conductor wire into the console receptacle marked “ISS” until it clicks into place. Do not force the connector into the receptacle.

To ISS

Console Location

2. Ensure that the ISS cable is not twisted through the access port.

Note:

The ISS must be assembled and connected to the console so that it is receiving

power before the console connection can be tested.

Once the console and ISS are both powered up, cable connection should be tested and

established.

Once the console is powered, it automatically enters Setup Mode. You can step through

the Setup Mode options, or exit the Setup Mode to test the connection and sensor read-

ings in Current Weather Mode. See “Setup Mode” on page 9 for Setup Mode options.

See “Current Weather Mode” on page 18 for viewing and verifying current weather

data coming from the cabled console.

To verify that the console is receiving data from the ISS through the console connec-

tion, see “Cabled ISS Assembly” in the Integrated Sensor Suite Installation Manual.

Console Location

Place the console in a location where the keyboard is easily accessible and the display is easy to read. For more accurate readings:

•Avoid placing the console in direct sunlight. This may cause erroneous inside temperature and humidity readings and may damage the unit.

•Avoid placing the console near radiators or heating/air conditioning ducts.

•If you are mounting the console on a wall, choose an interior wall. Avoid exterior walls that tend to heat up or cool down depending on the weather.

•If you have a wireless console, be aware of possible interference from cordless phones or other devices. To prevent interference, maintain a distance of 10 feet between the Vantage Pro2 console and a cordless phone (handset and base).

•Avoid positioning a wireless console near large metallic appliances such as refrigerators, televisions, heaters, or air conditioners.

•The console antenna does not rotate in a complete circle. Avoid forcing the console antenna when rotating it.

Table & Shelf Placement

The console kickstand can be set to three different angles allowing five different display angles.

1.Install the two round rubber feet on the bottom of the console. The rubber feet help prevent damage to furniture and surfaces.

Console Location

2. Lean the kickstand out by pulling on its top edge.

You’ll see the indentation for your finger at the top edge of the console.

3. Slide the catch to rest the kickstand in the appropriate angle.

Choose low angles for display on a coffee table or other low area. Choose higher angles for display on a desk or shelf.

4. Install the two rubber channel feet on the kickstand.

If necessary, pull up on the stand to close it. It will be a little tight, so it’s okay to push hard enough to get it to slide.

Console Location

Wall Mounting

The console mounts to the wall using two keyholes located on the back of the case. To mount the console on a wall:

1.Use a ruler to mark two mounting hole positions on the wall 8 inches (203 mm) apart.

8" (203mm)

Drill two 3/32" or 7/64" (2.4 to 2.8mm) holes

8" (203mm) apart for the #6 x 1" mounting screws.

This is a representation for the mounting hole positions. This template is not true to size.

If installing a cabled Vantage Pro2 console with sensor cable running inside the wall, mount the console over an empty switch box.

2.Use a drill and a 3/32 or 7/64''(2.5 mm) drill bit to drill two pilot holes for the screws.

3.Using a screwdriver, drive the two #6 x 1'' pan head self-threading screws into the wall. Leave at least 1/8'' (3 mm) between the wall and the heads of the screws.

4.If the kickstand has been pulled out from the case, push it back into its upright and locked position.

5.Guide the two keyholes on the back of the console over the two screws.

Chapter 3

Screen 7: Time Zone

The console is pre-programmed with a combination of US time zones and the names of major cities representing time zones around the world. You can also configure your time zone using the Universal Time Coordinate (UTC) offset.

Screen 7: Time Zone

Note:

UTC offset measures the difference between the time in any time zone and a stan-

dard time, set by convention as the time at the Royal Observatory in Greenwich,

England. Hayward, California, the home of Davis Instruments, observes Pacific Stan-

dard Time. The UTC offset for Pacific Standard Time is -8:00, or eight hours behind

Universal Time (UTC). When it’s 7:00 pm (1900 hours) UTC, it’s 19 - 8 = 1100 hours,

or 11:00 am in Hayward in winter. When daylight saving time is observed, an hour is

added to the offset time automatically. Use this function in correlation with Screen 8,

Daylight Saving Settings.

1.Press the + and - keys to cycle through time zones.

2.If your time zone is not shown, press 2ND then press the + and - keys to set your UTC offset.

3.Press DONE to select the time zone or UTC offset shown on the screen and move to the next screen.

Setup Mode

Screen 8: Daylight Saving Settings

In most of North America (except Saskatchewan, Arizona, Hawaii, and the Mexican State of Sonora); and Europe use the AUTO daylight saving setting. The console is preprogrammed to use the correct starting and stopping dates for daylight saving time in these areas, based on the time zone setting in screen 7.

Stations located outside North America and Europe, or in areas that do not observe daylight saving time should use the MANUAL setting.

Screen 8: Daylight Saving Settings

1.Press the + and - keys to choose Auto or Manual.

2.Press DONE to move to the next screen.

Screen 9: Daylight Saving Status

Use this screen to either verify the correct automatic daylight saving status or to set daylight saving manually.

Screen 9: Daylight Saving Status

1.If Daylight Saving setting is MANUAL, you will have to set the time correctly when it changes. However, to maintain accurate calculations, you also need to use the + and - keys to turn daylight saving time on or off on the appropriate days of the year. If you have an AUTO daylight saving setting, the console displays the appropriate setting based on the current time and date.

2.Press DONE to move to the next screen.

Screen 10: Elevation

Meteorologists standardize barometric pressure data to sea level so that surface readings are comparable, whether they’re taken on a mountainside or by the ocean. To make this same standardization and ensure consistent readings, enter your elevation in this screen.

Screen 10: Elevation

Note:

If you do not know your elevation, there are several ways to find out. Many atlases

and almanacs include elevation for cities and towns. You can also check with the ref-

erence department of your local library, or refer to internet resources. (See “Screen 5

and Screen 6: Latitude and Longitude” for a list of web sites.) The more accurate you

are, the better; but a reasonable estimate works too.
