The solar/leafwettness sensor must be pointed South and must be free of shadows created by the
other sensors (near the top of the mast is normally the best). Take care that the sensor is perfectly
level. Run the solar sensor cable to the junction box and plug it in to RJ11 connector.
The rain collector is normally mounted on the mast. It should be mounted as low as possible to
reduce windage and to limit 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 cable
that must be connected to the junction box.
Mount the junction box under the rain collector using the hose clamps that are installed on the box
(see figure 1). Remove the front cover of the junction box, inserting the connectors from the sensors
and intemediated cable through he hole in the bottom of the junction box and then out of the front of
the box. Plug all the sensor connectors in the junction box being careful not to plug the sensor
cables into the larger red color coded RJ-45 intermediate connectors
The intermediate cable (red) should be plugged in to one of the junction box RJ-45 intermediate
connectors (color coded red), then run into the building where the PC is located. Pull the excess
cable out of the j-box. Carefully seal the bottom hole in the box from the inside by using the
plumber’s putty provided to keep bugs out. Be sure and replace the rubber gasket on the junction
box so that it can remain watertight. If you do not properly put the j-box cover and seal on, the j-box
will leak water and the system will fail. It is a good idea to avoid running the intermediate cable close
to noisy devices such as florescent lights and electric motors. Plug the red intermediate cable RJ-45
connector into the host adapter (HA3 or HA4) and then attach the host adapter to serial port on the
PC. If you have a barometric pressure sensor, plug it also in to the host adapter making sure that
the TWI dropping adapter is in line. Your hardware is now installed, go to software installation.
SOFTWARE INSTALLATION
We strongly suggest that all the 1-Wire Weather Station Sensors, intermediate cable,
junction box and host adapter be connected to your PC, and that your software be installed
on your computer and tested prior to the installation of your sensors on the roof, so that you
may become familiar with the operation of this equipment.
OneSix Server
Find the diskette that is labeled OneSix Server. The OneSix Server is also available via the internet
at www.pointsix.com. Plug all of your hardware in to your computer (through the J-box if supplied)
then install the OneSix server software. The default folder for the OneSix server is c:\onesix (if you
put OneSix server into any other folder, Weather View will not be able to find the server). Click onto
the OneSix server icon and load. OneSix Server will search the 1-Wire Microlan for sensors and
then write to the Onesix.ini file recording your configuration.
To make a DDE link into another program such as Word 97, click on the OneSix DDE Server
button. Then click on DDE Variables in the OneSix Server. Highlight the sensor description that you
