5. Slide the two sections of the Radiation Shield completely together.
6. Fasten the two sections together using the 3 flat washers, lock washers, and
wing nuts. The wing nuts should be finger-tight.
Procedure 5. Locate and cut the rain collector 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 the rain collector cable extension.
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 side of the 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 about 1½ inches (38 mm) of the
jacket (the outer covering) of the cable.
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.

Page 8 Installation - ISS with Internal SIM
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.
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 Interface 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 the UV and Solar Radiation sensors through it, if
included on your station.
2. Wireless ISS: Run the SIM Power cable 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 grommet in the right slot, adjusting the inside cable lengths as
needed for a tidy installation.

Powering the Wireless ISS SIM
Wireless versions of the ISS receive most of their power from the solar panel
installed next to the rain collector. Backup power is provided by a 3-volt lithium
battery.
1. Install the new battery in the SIM. The green test LED should blink once on
power up.
2. Check that the DavisTalk transmitter DIP switches on the new transmitter
board match those on 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 ISS only)
Even after removing the battery, the old transmitter board will still have some
power reserves and will continue to transmit data 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 fine 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 old transmitter board DIP switch #4 to
the ON position. This will put the board in Test Mode, and more quickly
discharge the board’s power reserves. 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.
