Installation - ISS with External SIM
Procedure 8. 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 9. Test Communication between the ISS and the con-
sole
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 should display these movements within a couple of seconds.
Procedure 10. Mount the ISS and SIM Housing
Refer to the following illustrations and refer to this section in your ISS Installa-
tion Manual to mount the ISS and the new SIM Housing. If you removed the ISS
from it’s mounted position to install the Fan-Aspirated ISS Retrofit Kit, you can
now re-mount it.
1.
To prevent erroneous rain counts by your rain collector, put the console into
Setup Mode before mounting it. Enter Setup Mode by pressing and holding
the DONE key while you press the “-”(down arrow) key.
2.
Install the ISS in it’s former location.
3.
Install the SIM housing adjacent to the ISS as shown in the illustrations.
4.
When you have finished mounting the ISS, exit Setup Mode on the console
by pressing and holding the DONE key.
5.
Return the old transmitter board to Davis Instruments in the new board’s
shipping box. Use the included return shipping label.
6.
(Wireless Models only) Please be sure the battery has been removed from
the old board before shipping it.
