Welcome to Vantage Pro2

TM

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. Wireless stations can also collect
data from optional Vantage Pro2 sensors. See “Optional Sensors” on page 2.

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.

Note: 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 up arrow, down arrow, left arrow, and right arrow navigation
keys are used to select command options, adjust values, and to pro­vide additional functions when used in combination with a com­mand key.

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.

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

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.

Battery

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 readings 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
connection, 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, follow these suggestions.

• 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.

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.

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.

Drill two 3/32" or 7/64" (2.4 to 2.8mm) holes
8" (203mm) apart for the #6 x 1" mounting screws.
