Configure and Set Up Your Vantage Connect
You will need to know the transmitter IDs of each transmitting station before you
configure your Vantage Connect.
Follow the prompts to enter setting and configuration:
1. Reporting Stations & Units of Measure
Enter the transmitter ID number of each of the transmitters that will be reporting to your Vantage Connect (up to 8). Choose a station type for each. (For
example, Vantage Pro2 ID: 1, Leaf and Soil Moisture Station: ID 2.) If using
repeaters, check the “Enable Repeaters” box and choose the final repeater’s ID
letter for each transmitter using repeaters.
Choose your preferred units.
Click Save.
2. Device Settings
For accurate barometric pressure data, enter the elevation at which your
Vantage Connect will be mounted. Fine tune this sensor by entering the local
barometric pressure reading. (Sources of this information include your local
airport or radio station)
Select your anemometer and rain collector types.
For accurate year-to-date rain data, enter the year-to-date rainfall as of today,
and when your rain season starts.
Station Alarms (Optional): Set alarms for high and low weather conditions.
Vantage Connect will send up to 20 (counting both activate and deactivate)
email or text alarm notifications per day, outside of the plan’s intervals, when
these conditions exist.
If necessary, you may calibrate temperature, humidity, and wind readings. (Be
careful when deciding to calibrate; Davis weather stations are factorycalibrated for accuracy and may not match less accurate or less local data such
as reported on television or a web page.) Enter the amount of offset you want
the temperature or humidity reading to be reported. For example, if you believe
your outside temperature data is consistently 2 degrees too low, enter +2. If you
believe the outside humidity data is consistently 5% too high, enter -5. You
must calibrate the wind direction if your anemometer cannot be mounted so
that the arm points true north. Enter the direction the arm points, if not zero, in
degrees from 1° to 359°.
Click Save.

Connect the battery
The Vantage Connect is shipped with one battery cable (the red, or positive cable)
disconnected to prevent battery drain. Connect the red cable to the red terminal.
IMPORTANT: When putting your Vantage Connect into cold storage, disconnect the
red cable.
Install the Vantage Connect
If you have not already set up your ISS or additional station, do so first. (See the
instruction manual that came with your ISS or additional station.)
Mount the Vantage Connect shelter
Choose a location for your Vantage Connect. It can be mounted on a pole or a flat
surface such as a wall or a wooden post. The shelter should be mounted within
transmission range of your ISS. (Maximum of 1000 feet (300 m), line-of-sight,
open air.)
It is important that the shelter be mounted so that the solar panel gets the greatest
amount of sunshine -- the solar shelter should be facing south (in the northern
hemisphere) or north (in the southern hemisphere).
Mounting the shelter may be easier if done by two people.
Mounting on a Flat Surface
Attach the shelter to the mounting surface in the desired location using the lag
screws and backing plates as shown below. Use a pencil or a center-punch to mark
the location of the pilot hole.
Mounting On a Pipe
Mount the Vantage Connect onto a pipe with an outside diameter of 0.84'' to 1.84''
(21 mm to 27 mm) using the U-bolts, backing plates, washers, and hex nuts
For mounting on larger diameter pipes, the housing can accommodate U-bolts with
5/6'' (8 mm) threads for pipes up to 2.40'' (61 mm) outside diameter (not provided).
Power Up Vantage Connect 6620 (GSM/2G)
Register your Vantage Connect online and wait 5 to 10 minutes BEFORE you power
it up to avoid a delay in uploading data. If you already powered up before
registering, remove power from the Vantage Connect, register, then repower.
1. If using a cabled Vantage Connect (6620C) with a cabled ISS, remove the
plug from one of the holes in the bottom of the shelter. Run the ISS cable up
through the hole. Outside the shelter, wrap a split grommet around the cable
and push the grommet securely into the hole. Plug the cable into the ISS cable

Weather Station
Cell Network
The Vantage Connect will now begin to acquire both the radio signal from the
weather station as well as the cell signal. You will be able to observe this by
watching the LED lights.
• While the Vantage Connect is searching for signals, the LED lights will flash.
The weather station status LED (top) will flash green. The cell status LED
(bottom) will flash blue.
• When the signals are acquired, the LEDs will stop flashing and stay on. When
the lights are solid green (weather station) and solid blue (cell network), the
station has acquired both signals and is connected and operating normally.
• After several minutes, the solid LED lights will time out and go off.
If there is a connection error, the lights will flash quickly. Their behavior will
indicate the type of error. See Vantage Connect 6620 (GSM/2G) Status LEDs: on
page 14.
The LED lights can be reactivated by pressing and releasing the blue status LED on/
off button. After pressing the button, wait for up to 30 seconds for lights to come on.

Power Up Vantage Connect 6621 & 6622
(CDMA & 3G)
It is important to register your Vantage Connect before powering it up to avoid a delay
in uploading data. If you accidentally power the unit before registering, it will
automatically go to sleep. After 24 hours, it will wake up and check for registration
again. If you already powered up before registering, remove power from the Vantage
Connect, register, then repower.
1. If using cabled Vantage Connect (6621C or 6622G) with a cabled ISS, remove
the plug from one of the holes in the bottom of the shelter. Run the ISS cable
up through the hole. Outside the shelter, wrap a split grommet around the cable
and push the grommet securely into the hole. Plug the cable into the ISS cable

Vantage Connect will now begin to acquire both the radio signal from the weather
station as well as the cell signal. As this is occurring, you may see the lights go on
an off or blink, but after about a minute, the lights will begin to indicate the status
of your connections. You will be able to use the lights to verify connection or
troubleshoot connection problems by watching the LED lights.
The lights flash when Vantage Connect is searching for a signal from the weather
station (upper LED) or a cell signal (lower LEDs). Once the signal is detected, all
four cell status lights will turn solid and stay on for a few minutes, indicating
success. It can take several minutes to acquire all signals.
See Vantage Connect 6621 & 6622 (CDMA & 3G): Normal and Error LEDs on
page 16 to ascertain what error is being indicated and to report to Tech Support.

Appendix A: Using an External Temperature
Probe with Vantage Connect
You may use an external temperature probe (product numbers 6475 or 6477) with
your wireless Vantage Connect. This reading will replace the Vantage Connect’s
“inside temperature” reading. You will need an oval split grommet available upon
request from Davis instruments (part number 7342.805). Remove the plug from of
the holes in the bottom of the shelter and feed the probe cable up through the hole.
Plug the cable into the jack (see illustration on page 2). Attach the grommet to the
cable and insert it snugly into the hole.
Appendix B: Using AC Power to Charge the
If your installation is in a low-light area or an area with prolonged periods of time
where temperatures stay below -4°F (-20°C), charging may be inhibited. You may
use Davis’s Optional AC Charger Kit, product number 6710, to charge the battery.
The kit allows you to replace the solar charger with AC power. The adapter has a
universal input (100 -240V, 50-60 Hz) and will work anywhere in the world. (A
wall-plug adapter may be necessary for use in some countries.) In a cold
environment, you will need to bring the Vantage Connect into a warmer
environment (above -4°F/-20°C) to charge the battery with the AC Charger Kit.,
 How can I tell if my battery voltage is getting too low?
Our server will monitor your battery voltage and will trigger an e-mail warning if
it should get critically low (approximately 14 days of power). The e-mail will go
to both the registered customer’s e-mail address as well as the alarm e-mail
address (if one has been set up).
 My installation is in a low light area. Can I add another solar panel?
Yes. You can add an Extra Solar Panel Kit (product number 6616).
 Can I add another battery? Can I charge the battery on AC power?
Yes. You will also need a Universal Shelter (product number 6618) in which to
mount the extra battery. Contact Tech Support for parts and instructions on adding
batteries. You may also use AC power to charge the battery. See Appendix B:
Using AC Power to Charge the Battery on page 11.

• Check power to the weather station. Make sure all cables are securely plugged
• Measure battery power with volt meter.
• Repower by unplugging the main power cable, waiting one minute, then
plugging it in again.
If data still is not uploaded, contact Tech Support.
 If I lose cell connectivity, but my Vantage Connect is still powered, how much data will
be stored?
The amount of data it can store is similar to a standard data logger and dependent
on your archive interval or subscription plan interval.
When the cell connection resumes, Vantage Connect will send this old data to in what we call “catchup mode.” In catchup mode, Vantage
Connect will send 15 records about every 2 minutes.

 How can I access my data if I am on site but don't have a PC with an internet
If you urgently need to access your weather data at your remote site but have no
access to a PC with an internet connection, you can connect a laptop (or PC)
directly to the Vantage Connect and download all of the archive records in its
memory using the supplied WeatherLink software. You will need an interface
cable. Please call Technical Support to request a Vantage Connect interface cable.
 Can I replace my battery?
Yes. Your Vantage Connect comes with a battery designed to charge in
temperatures as low as -4°F/-20°C.
If you need to replace the battery and your installation is in a location with low
temperatures, you should replace the battery with a Davis battery, product number
If your installation is in a warmer climate, you may replace the battery with a 6volt, 12 Ah, gel cell battery which will only charge at temperatures above 0°C. See
Specifications on page 17.
(With either battery, your Vantage Connect can function down to -40°F/C.)
 What do the LED lights indicate?
If there is an error in getting a signal, the status LEDs will flash to indicate the
type of error.
