Preparing the ISS for Installation: Cabled ISS: Powering and Testing

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 modu-
lar receptacle labeled “ISS.”
Plugging the console cable into the console powers the ISS and establishes commu-
nication between the ISS and the console. Your ISS should immediately begin col-
lecting 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 Recep-
tion.”
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.
