Introduction
The Integrated Sensor Suite (ISS) collects outside weather data and sends the data to a
Vantage Pro console or Weather Envoy. Wireless and cabled versions of the ISS are
available, as well as standard and plus versions. The Wireless ISS is solar powered and
sends data to the console via a low-power radio. The Cabled ISS sends data and
receives power via the console cable.
Standard versions of the ISS include a rain collector, temperature sensor, humidity
sensor and anemometer. The ISS Plus adds a solar radiation sensor and an ultra-violet
(UV) sensor. Temperature and humidity sensors are mounted in a passive radiation
shield to minimize the impact of solar radiation on sensor readings. The anemometer
measures wind speed and direction and can be installed adjacent to ISS or apart from it,
see “Siting the ISS and Anemometer” on page9 for siting guidelines.
The solar and UV sensors are mounted next to the rain collector cone. Solar and UV
sensors are available separately to upgrade a standard ISS. See “Appendix B: Optional
Accessories” on page 20.
The Sensor Interface Module (SIM) contains the “brains” of the ISS and is located on the
bottom of the radiation shield. The SIM collects outside weather data from the ISS
sensors and then transmits the data to your Vantage Pro console or Weather Envoy.
Included Components and Hardware
The ISS comes with all the components and hardware shown in the following illustrations. If you purchased your ISS as part of a Weather S tation, additional components may
be included in the package that are not shown here.

Connect the Anemometer Cable to the SIM
1. Unwind the coil of cable enough to work with the anemometer . Do not unwind the
entire coil of anemometer cable just yet.
2. Gently insert the end of the anemometer cable into the connector labeled “WIND” on
the SIM.
3. Press the cable fully into the channel next to the connector as shown on the next
page.
Cabled ISS: Powering and Testing
Applying Power
The 100' (30 m) console cable provides power to the ISS and is used to send data from
the ISS to the console. The console cable can be extended up to 1000' (305 m) in length‘.
1. Locate the 100’ console cable included with your system.
2. On the SIM, gently insert one end of the 4-conductor cable into the modular connec-
tor located apart from the sensor connectors. Refer to the figure “SIM Connections”
on this page.
3. If you haven’t powered up the console yet, refer to the installation instructions in the
Vantage Pro Console Manual and apply power to the console.
4. On the back of your console, insert the other end of the console cable into the modular receptacle labeled “ISS.”
Plugging the console cable into the console powers the ISS and establishes communication between the ISS and the console. Your ISS should immediately begin collecting weather data and start sending the data to the console. Data is sent through
the cable that you connected during the preceding step in order to power the ISS.
Verifying Communication
Use these steps to verify reception of ISS data at the console for a Cabled Vantage Pro
and to test the operation of the ISS sensors.
1. If the console is in Setup Mode, press and hold down the DONE key until the “Current
Weather” screen appears.
The console should now display sensor readings from the ISS.
2. Near the center of the screen, look for inside and outside temperatures.
3. Spin the wind cups to check wind speed, pressing the WIND key if necessary to alter-
nate between speed and direction in the compass rose.
4. Turn the wind vane, and allow 5 seconds for the wind direction display to stabilize
before moving it again.
5. Approximately one minute after power-up the outside relative humidity reading
should be displayed on the console.
6. If you have a UV sensor and or solar radiation sensor, press the UV key for current
ultraviolet readings or press 2ND then press SOLAR for solar radiation readings.
UV and solar readings should be zero or close to zero if the ISS is inside. Zero is a
valid reading — dashes are displayed if no data comes from the sensors.
7. Current weather data displayed on the console confirms successful communication.
If the console is not receiving data, proceed to “Troubleshooting Cabled ISS Reception.”
8. You may wish to disconnect the console cable from the SIM at this point to ease the
installation of the ISS.
9. Close the SIM housing cover on the ISS.
10. Continue on to “Prepare the Rain Collector” on page 8.

Troubleshooting Cabled ISS Communication
If your console is not receiving sensor readings from the ISS, please try the following
troubleshooting procedures.
1. Check the console to make sure you are using the supplied AC adapter. Other adapters may not work.
2. Make sure the console cable is firmly plugged into the ISS connector on the console.
3. At the ISS, check that the console cable is firmly plugged into the correct modular
connector. Refer to the figure “SIM Connections” on page 4.
4. Verify that all sensor cables are firmly plugged in.
5. If you still don’t get readings, reboot the console by disconnecting the AC power
adapter from the console and removing the console batteries for at least 30 seconds.
6. If your console is still not displaying sensor readings from the ISS, please contact
Davis Technical Support. See page 18 for details.
Wireless ISS: Powering and Testing
Use these steps to power a Wireless ISS, to verify communication with the console, and
to verify the operations of ISS sensors.
Note: A super capacitor stores energy from the solar panel for power at night. The bat tery powers a
Wireless ISS when the super capacitor is depleted.
Applying Power to a Wireless ISS
1. Insert the 3-volt lithium battery into the SIM.
Once powered, your ISS will immediately begin transmitting data to the console.
CAUTION: Be sure to match the “+” sign on the battery with the “+” sign on the SIM.
Checking Transmitter ID
A Vantage Pro console can receive data from up to eight different wireless stations.
1. The default transmitter ID for the ISS and
console is ‘1’.
In most cases it will not be necessary to
change the transmitter ID. Your console
and ISS should begin communicating
automatically when power is applied.
2. If it is necessary to change the transmitter ID, remember to use the same the ID for the ISS and console. See “Appendix A:
Wireless Transmitter IDs” on page 19.
Verifying Communication with the Console
1. If you haven’t powered up the console yet, refer to the Vantage Pro Console Manual
and apply power the console.
Note:The console automatically enters Setup Mode when powered up.
2. If the console is not in Setup Mode, press and hold the DONE key then press the “-”
key.
You should see the words: “RECEIVING FROM...” and “STATION NO.” followed by
the transmitter IDs that your console detects.
3. Look for the ISS transmitter ID which will be ‘1’ unless you have changed it. If the
console shows the ISS transmitter ID then your ISS is being detected.
