Remote Weather Station™ with Solar Power
The Texas Weather Instruments Remote Weather Station will send your current weather conditions directly to the internet without any infrastructure as log as a Sprint or Verizon cell signal is available. Data from the roof top sensors is sent via a built in cell modem to the TWI data center every two minutes. An internet weather network (wunderground.com) will then log and display your data via a web browser at no charge to you. You can view your weather conditions from your computer, tablet or smart phone from anywhere in the world. The weather application, WeatherView32 Home is available online at no charge. Weatherview32 can run locally or remotely to log and display data directly on to a Windows computer. Your WeatherView32 Home serial number is in the back of this manual along with instructions on how to download it from the Web.
Included with the RWS-Solar system is a wind direction and speed sensor, a pagoda mounted temperature/humidity sensor, rain collector, pressure sensor, solar powered outdoor controller, and cell modem. Optional sensors include solar radiation and lightning. Please note that the RWS-Solar is a solar powered weather station. The RWS Solar outdoor controller needs to be in full sunlight at least two hours per day to recharge its battery. Placing the RWS Solar Outdoor controller in a shaded area will cause the system to be starved for power. If you want an externally powered unit you should have the RWS.
The RWS comes with the modem already provisioned with a three month data plan. Users will need to contact TWI to extend their data plan past the first three months. Look for a sticker in the RWS enclosure or in the RWS manual for
a internet link to your data.
The standard NWS-Solar uses three outdoor sensors and an internal pressure sensor to gather weather data. The wind direction and speed sensor, the temperature/humidity pagoda and the rain collector (see figure 1) are designed to mount to a television type mast (not provided). The cables from the sensors go into mast mounted RWS Controller. All of the sensor cables are color-coded and plug directly into the Outdoor Controller.
C A U T I O N !! :BE EXTREMELY CAREFUL NOT TO TOUCH ANY HIGH POWER LINES DURING INSTALLATION OF THE VARIOUS SENSORS!!!
We strongly suggest that you become familiar with your weather station before you install it on the roof. Plug all the sensors into the RWS following the color codes. Any blue cable can go into any blue receptacle, any red into red, etc. The standard wind sensor is the TWI Analog sensor which has two RJ-45 attached. Put the yellow plug into the yellow receptacle and the single orange wire RJ-45 into the orange receptacle next to the yellow labeled TXWX. When first powered up the the red “alive” LED on the RWS board will flash indicating that the unit is operating. On the modem a red light will come on solid indicating that the modem has power. The modem will flash slowly when it has acquired a signal and connected to the network. The red data LED will flash when the RWS has successfully sent data to the TWI data center. When the modem red LED flashes quickly, the modem is sending data on the network. Both of the RWS LED’s will be disabled after five minutes to save power. The modem LED will continue to function. To leave the RWS LED’s on at all times install jumper 4 on the RWS board.
Station Setup: The station is pre-configured from the factory and should not need to be configured unless you want your weather station to output data in metric mode.
Station Calibration: The station is pre-calibrated from the factory. The only item that needs to be calibrated is the barometric pressure. Obtain the current pressure reading for your area via the internet of from the nightly news and change the weather station pressure calibration to match.
Station Weather Network: Click to enable / disable sending weather data directly to Wundergound.com. Go to http://www.wunderground.com/wxstation/signup.html to obtain a Station ID and Password if we have not provided one for you.
Enable: Check mark to enable the upload of weather data to Wunderground.com.
ID: Enter the Station ID that Wunderground.com assigned you.
Password: Enter your Wunderground.com password, which is the same as you member login password.
Send Period: Enter the quickest send period which is 3.
After setup it should take about a day for your data to show up on Wunderground.com. Put your zip code in the Wunderground search window, scroll to the bottom of the page and look for your station. If your data does not show up on Wunderground, go to troubleshooting in your manual.
Installation of Roof Sensors
Only proceed to the installation process if you have successfully tested your NWS-Solar inside. The wind direction and speed sensor is normally mounted on television type antenna masts (see Figure 1). For best results the wind sensor should be mounted 10 feet above the roof of the building. Higher installation yields more accurate readings. There is one yellow cable that must be strung from the wind sensor to the Outdoor Controller. The wind direction sensor is calibrated at the factory and should be installed with the wind sensor arm pointed to the North. The wind sensor can be mounted in any direction and re-calibrated via the a web browser, but it is more convenient to use the pre-calibrated North reference. If calibration is necessary after the unit is already mounted, pick a calm day or immobilize the wind vane by hand and use calibration mode to make these changes. The outside temperature/humidity pagoda should be mounted about 1 foot under the wind sensor. Again, we suggest at minimum a 10′ mast for commercial installations to overcome the artificially high readings generated by a hot roof.
The RWS enclosure should be installed with the integral solar panel facing South and cable opening pointed down on the mast. Using the two supplied hose clamps mount the unit about 5 feet above the roof or just below the rain collector. If your RWS is mounted on a mast that is in on ground, you should consider mounting the RWS high enough so that it is out of reach. Open the Outdoor Controller and feed the sensor cables through the fitting on the bottom of the Outdoor Controller enclosure and plug them into the the matching color-coded RJ45 receptacles. Use the black cable ties every two feet to secure the cables to the mast. If you have the optional lighting sensor place the chrome BNC connector on the chrome BNC receptacle inside the RWS and turn the ring 1⁄4 turn clockwise.
The rain collector is normally mounted on the mast. It should be mounted low at the same level but on the opposite side of the pole from the Outdoor Controller. Mounting the rain collector low reduces windage and limits the movement of the mast, which can cause false readings. The collector should be mounted in a manner that allows rain to enter the collector unencumbered by surrounding obstacles. Use a bubble level to make sure that the collector is perfectly level with the ground. Failure to level the collector will cause inaccurate rainfall readings. The rain collector has one blue cable, which must be connected to the Outdoor Controller.
Insert the small foam rubber block into the bottom cable nipple to prevent bugs from entering the enclosure. Do not plug the cable nipple with any kind of sealant as it is important for the system to breath.
Power up the RWS by moving the black switch up. The red keep alive LED and data lights should start flashing on the Controller board along with the modem red LED.
Close the cover on the Outdoor Controller and check that the gap is even around the enclosure. Failure to properly close the enclosure will allow water to enter and void the warranty. Raise the solar panel to the 45 degree angel and install the panel support bracket. This completes your installation.
There are four jumpers (eight small pins) labeled JP2 near the fuse on the Outdoor Controller board that are preset at the factory. You should no normally change the jumpers. Jumper 1 is labeled 1 and when closed leaves the board 10V on at all times. This must be jumped for the TWI digital wind sensor and the lightning sensor. Jumper 2 selects TE pulse style wind sensor over the generator style. Jumper 3 selects the cell modem mode. Jumper 4 sets the LEDs to never turn off.
Go to the Station FTP tab to set up the ASCII FTP function. The NWS has the ability to send and ASCII file as often as once per minute to your website. This feature is handy if you want a weather application like WeatherView32 to grab the data outside of your firewall.
Common Items: Enter the host name, the user name and password for the server.
Basic Items: Checkmark the enable box to send the data along with the path to the server. Leave the filename twidata.txt and the send period to once per minute if you are using WeatherView32. The old data will be overwritten with the new data.
Archive Items: Checkmark the enable box to ftp archive data. You will select a different path for the same web-server for the archive items. The Archive FTP files are identical ASCII as the Basic FTP files except they have incremental file names. Each Archive file has a different name so the old file is not overwritten but stays on your server. Please be very careful when you turn this feature on, as it will quickly clutter up your server. Old files must be erased manually.
WeatherView32 Home Edition is a Windows weather application that is supplied with the NWS. Refer to the WeatherView32 manual to install WeatherView32. After installation go to the setup tab in WV32, then to Weatherview Properties, the Connection. Enable the check box and enter the path to the weather data into the URL dialog box. If you do not know the IP address for your data refer to the label inside the RWS enclosure or the label in your RWS manual.
You can telnet into the weather station for communication troubleshooting with a Windows computer. Open a DOS window by typing CMD in the search start window. If you have Vista or Windows 7 you will probably need to install the telnet program via the control panel, programs, program and features, turn windows features on and off. From the DOS prompt type telnet space then the IP address of the weather station IE “telnet 192.168.1.204”. Type the weather station log in name and password. The Telnet screen shown below should appear. Pick item 1 through 4 for help with communications issues.
