RAWS-H Remote Automated Weather Station 1. Introduction The RAWS environmental enclosure can be used for configuring a custom Remote Automated Weather Station (RAWS) that matches the requirements of your application. The aluminum environmental enclosure houses a 12 V rechargeable battery and a CR1000 datalogger. The outside of the enclosure has color-coded, keyed connectors (Figure 1-1) for attaching the sensors.

Inside Environmental Enclosure (optional equipment shown) NOTE 2 Customized Handar sensor programming can be developed for a nominal fee.
RAWS-H Remote Automated Weather Station 2. Getting Started NOTE Set up and test your station before field deployment. NOTE Keep this manual and the CR1000KD Keyboard Display with the RAWS. Review the station siting and orientation section before field deployment. If a problem is encountered, review the equipment wiring and troubleshooting sections in this manual.
RAWS-H Remote Automated Weather Station faces south (northern hemisphere) minimizing the chance of shading from other weather station structures. Reflective surfaces and sources of artificial radiation should be avoided. Level the solar radiation sensor. 3.5 Wind Speed and Direction A wind sensor should be located over open level terrain and at a distance of at least ten times (EPA) the height of any nearby building, tree, or other obstruction. 3.
RAWS-H Remote Automated Weather Station 4.3 Solar Radiation The solar radiation sensor is connected to the RAWS connector panel “SOLAR RAD SDI-12” connector COLOR CODED GREEN. The pyranometer sensor is internally wired from the RAWS connector panel to the CR1000 datalogger.
RAWS-H Remote Automated Weather Station 4.6 Barometric Pressure The barometric pressure sensor (part #CS100-QD) is mounted inside the RAWS environmental enclosure and the sensor wires are attached to the CR1000 printed circuit board wiring panel.
RAWS-H Remote Automated Weather Station matter; either lead can be connected to either terminal. The CH100 charger/regulator has two functions: 1) blocks any current flow from the battery to the solar panel, and 2) limits the source current to the battery. 5.1.3 Troubleshooting, Solar Panel If a problem with the solar panel is suspected, the solar panel may be checked by measuring the voltage output from the solar panel.
RAWS-H Remote Automated Weather Station connectors. The battery red lead connects to the positive battery terminal and the black lead connects to the negative terminal. Connect 12 V power to the datalogger and/or peripherals using the “+12 and Ground” terminals. The ON-OFF switch applies power to these 12 V terminals. WARNING Reversal of battery polarity will damage the CH100 or battery. CAUTION A battery must be attached for the CH100 to function correctly as a power supply.
RAWS-H Remote Automated Weather Station batteries connected. The battery connections are diode isolated; however, if one of the batteries fails, it could draw all the charging current and the other battery will be discharged. WARNING Reversal of battery polarity will damage the CH100 or battery. CAUTION It is possible to leave two batteries connected.

RAWS-H Remote Automated Weather Station 5.5 Voice Radio Interface 5.5.1 General Description, Voice Radio Interface (part #VSP3) The DACOM Voice Radio Interface (part #VSP3) shown in Figure 5.5-1 is mounted inside the RAWS environmental enclosure. The VSP3 converts data into voice messages that can be transmitted via UHF or VHF transceiver. The VSP3 Vosponder uses phonetic native text string to speech conversion, which provides for an unlimited vocabulary.
RAWS-H Remote Automated Weather Station 5.5.3 Troubleshooting, Voice Radio Interface (part #VSP3) If a problem with the voice radio interface (part #VSP3) is suspected, the VSP3 may be checked by measuring the +12 V and Ground terminal on the VSP3. Acceptable readings are +11 VDC to +14 VDC. Verify the sensor wires are securely fastened to the VSP3 connector and the CR1000 printed circuit board wiring panel. If problems persist, try a substitute. 5.6 CR1000 Keyboard/Display 5.6.
RAWS-H Remote Automated Weather Station 5.6.2 Wiring, CR1000 Keyboard/Display (part #CR1000KD) The CR1000 Keyboard/Display (part #CR1000KD) connects to the CR1000 PC board “CSI/O” 9-Pin connector using a standard RS-232 serial cable (part #10873) that ships with the RAWS station. 5.6.
RAWS-H Remote Automated Weather Station 5.7.2 Wiring, CR1000 Datalogger The CR1000 datalogger is mounted inside the RAWS environmental enclosure and fastened to the CR1000 printed circuit board wiring panel. Connect 12 V power to the CR1000 printed circuit board wiring panel green power connector. The CH100 ON-OFF switch applies power to the 12 V terminals. 5.7.
RAWS-H Remote Automated Weather Station station. More difficult maintenance, such as sensor calibration, sensor performance testing (i.e., bearing torque), and sensor component replacement, generally requires a skilled technician, or send the instrument to Campbell Scientific. A station log should be maintained for each weather station that includes equipment model and serial numbers and maintenance that was performed. NOTE Consult the equipment manual for routine maintenance procedures.

RAWS-H Remote Automated Weather Station 8.1.2 USGS Web Calculator The USGS provides an easy way of determining declination of a specific site. Since magnetic declination fluctuates with time, it should be adjusted each time the wind sensor orientation is adjusted. The calculator can be accessed at: www.ngdc.noaa.gov/geomagmodels/Declination.jsp. Figure 8.1-4 shows an example for Logan, UT. FIGURE 8.1-4. USGS Web Calculator In the example above the declination for Logan, UT is 12º 24′ or 12.4º.
