2.1 Installation Considerations
Prior to installing the WS-16-A, you should be aware of several important points that
must be taken into consideration when choosing a site for the data acquisition module
and sensors.
2.1.1 Data Acquisition Module
The data acquisition module should be located as close as possible to the computer
that will be used to communicate with the WS-16-A. RS232 communications (the
communication protocol used by the WS-16-A) is designed for use over short
distances, and the cable connecting the module to the computer should not be longer
than 200 feet (60 meters), although longer lengths may work. If this arrangement is not
feasible, an RS232 to RS422 converter can be added to allow longer cable runs.
2.1.2 Tripod Tower
The five-foot tripod tower provided with the WS-16-A is constructed of steel tubing for
durability and strength. Horizontal bracing is a feature of the tripod tower. The tripod’s
foot brackets can be bolted onto a concrete foundation or a wooden platform. The wind
speed and direction sensor mounts on top (the tapered end) of the five-foot aluminum
sensor mast. The solar radiation shield (for the temperature and humidity sensor) and
the rain gauge mounting arm are supplied with u-bolts to clamp onto this mast. For
stability, we recommend that the mast be inserted into both of the tripod’s collar clamps.
Guy kits are recommended for areas of high winds and ground kits are recommended
for areas with lightning activity.
Caution
: When installing the wind sensor, make sure that the sensor and cable are well
clear of any power lines.
2.1.3 Lightning Protection and Grounding
A brass lightning protection ground screw, located on the data acquisition module, is
the path to ground for all of the lightning protection circuitry in the WS-16-A. Connect
this screw to a grounded outlet or water pipe. In areas subject to severe lightning
activity, we recommend that you install a grounding rod.
2.2 Power Connections
The WS-16-A can be operated from a standard 110Vac outlet, a standard 220Vac
outlet, or from an external 12Vdc battery.
2.2.1 Standard Outlet
A wall transformer is provided with the unit for operating from a standard 110Vac outlet.
An optional wall transformer is available for operating from a 220Vac/50Hz power
source. The wall transformer provides a nominal 12Vdc.
