VANTAGE PRO® AND VANTAGE PRO PLUS
Fan-Aspirated ISS Retrofit Kit
Installation Instructions Estimated Time Required: 60 Minutes
These instructions describe how to install the Vantage Pro® Fan-Aspir ated Integrated Sensor Suite (ISS) Retrofit Kit.
This retrofit kit applies to all cabled and wireless versions of the fan-aspirated ISS.
Components
The Fan-Aspirated ISS Retrofit Kit includes the following components:
• Externally-mounted SIM with housing
• Temperature/Humidity sensor module
• Rain Collector cable extension
• New SIM Power cable
• Splice kit to attach extens ion cables
• Mounting hard wa r e for new SIM housi ng
Tools for Setup
In addition to the kit, you will need the following tools:
• Small Phillips-head screwdriver
• Pliers or other crimping tool
• Other hand tools depending on your installation
Tip: If your Wireless Fan-Aspirated ISS has been in service for over a year, this would
be a good opportunity to replace the C-cell batteries used by the fan.
Installation Outline
Early version of the fan-aspirated ISS mounted the sensor interface module internally inside the radiation shield. Newer versions of the fan-aspirated ISS mount the SIM module in an external housing. The installation procedure for the two different versions are outlined separately below.
CAUTION:Please work on your Vantage Pro ISS in a safe place. We strongly recommend
that you remove the ISS from its installed position before beginning these steps.

Installation - ISS with Internal SIM
Use these procedures to install the retrofit kit on an ISS that has the SIM mounted inside the radiati on shield .
Note:Use this procedure if your ISS has wing nuts on the bottom.
Procedure 1. Rem ove the ISS from its Installed Position.
In order to take down your ISS you wil l first need to disconnect the anemomet er cable. If you h ave a Cabl ed Vantage Pro station , you w ill al so n eed to discon nect the console cable from the ISS.
CAUTION:Please work on your Vantage Pro ISS in a safe place.
1. At your Vantage Pro console, press and hold the DONE key and then pr ess the “-” (down arrow) key to put the conso le in Setup Mode. This will pre­vent the reception of erroneous rain counts from the rain collector.
2. If you have mounted the anemometer remotely from the ISS or if you have a cabled ISS you will need to open the radiation shield. Remove the three wing nuts and separate the upper and lower sections of the radiation shield.

4. Install the Junction Board cover as shown above. The cover installs easily by pressing it into place.
5. Slide the two sections of the Radiation Shield completely together.
6. Fasten the two section s together usi ng the 3 f lat washe rs, lock washers, a nd wing nuts. The wing nuts should be finger-tight.
Procedure 5. Locat e and cut the rain collect or cable.
These cables must be extended in order to reach the SIM housing.
1. Locate the rain collector cable hanging underneath the rain collector base. The rain collector cable is labeled “RAIN” near the modular connector.
2. Take the wire cutters and cut the rain collector cable next to the modular “phone-style” connector.
Procedure 6. Splice on t he rain collector cable ext ension.
For the best connection, note the following suggestions:
• Try to place the spliced connections in a location shielded from rain.
• When securing cables, place a cable clip or tie on each sid e of t he connec-
tion point so the movement of the cables does not cause the connection to pull apart.
• Use the smaller splice connectors to extend the rain collector cable.
Follow this procedure to splice on the rain collector cable extension:
1. Use a wire stripper or a knife to strip away a bout 1½ inches (38 mm) of the jacket (the outer covering) of the cab le.
Do not strip away any of the colored insulation on the individual wires. Repeat this procedure for the end of each cable you are connecting.
Strip Shielding
2. Take a wire from one of the cables and place it into one of the holes at the end of a splice connector .
Make sure you push the wire all the way in. You can check this by looking through the clear side of the splice connector.
Installation Outline Page 7
Page 8
3. Take the same colored wire from the other cable and place it into the other hole at the end of the splice connector.
Make sure you push the wire all the way in. You can check this by
looking through the clear side of the splice connector.
Using Splice Connector
4. Use pliers to snap the cap into place, securing the wires.
Use the provided yellow splice connectors.
5. Repeat this procedure for each pair of wires to be spliced.
6. Use a cable tie to secure the two cables together as shown. Doing this provides a measure of strain relief which should prevent the
wires from pulling apart under normal conditions. Cut off the excess cable tie when it is secure.
7. Gather the wires and splice connectors neatly together and secure with a cable tie in a protected location up close under the rain collector base.
Procedure 7. Connect Sensor Cables to the New SIM.
The ISS sensors are connected by cables to the Sensor Interfa ce Module (SIM), located inside the new SIM housing. The SIM contains electronics that measure and store weather values for transmission to the console via cable or radio. The SIM housing protects the SIM from the elements and provides easy access to SIM cable connections.
1. Take one of the square rubber grommets from the bottom of the SIM hous-
ing and run the cables for th e UV and Solar Radia tion sens ors thr ough it , if included on your station.
2. Wireless ISS: Run the SIM Power cabl e through this first grommet.
3. Take the second square rubber grommet and run the Rain Collector, Ane-
mometer, and Temp/Hum sensor cables through it.
4. Cabled ISS: run the console cable through this second grommet.
5. Install the first grommet in the left slot in the SIM housing, and install the
second gromme t in the right slot, adjusting the inside ca ble lengths as needed for a tidy installation.

2. Check that the DavisTalk transmitter DIP switches on the new transmitter board match those o n the old board. Change the settings if necessary.
3. Connect the SIM power cable.
Note:DIP switch #4 on the new transmitter board should be in the OFF position.
Procedure 9. Decommission the old SIM (Wireless I SS only)
Even after removing the battery, the old transmitter board will still have some power reserves an d will conti nue to transmit dat a to your Vantage Pro console for up to 8 hours. In order to prevent the old transmitter board from sending erroneous data to your console, change the DavisTalk transmitter DIP switch setting on the old board.
1. Remove the battery from the old SIM.
1. Use a pen or other device with a fi ne point to change the setting of DIP switch # 1, #2, or #3. You only need to move one of these switches to change the ID setting.
2. As an added precaution, change the ol d tra ns m itt er b oard DIP switch #4 to the ON position. This will put the board in Test Mode, and more quickly discharge the boar d’s pow er r e serves. In Test Mode the green LED test light will flash approximately every 2.5 seconds.
Procedure 10. Test Communication
Test your ISS to verify it is communicating with your Vantage Pro console by spinning the wind cups or turning the weather vane.
• If your console is in Setup Mode, you will need to exit Setup Mode to
perform this test. Exit Setup Mode by pressing and holding the DONE key.
• The console shoul d display these mov emen ts within a coup le of seco nds.
