RAWS-F Remote Automated Weather Station for Fire Weather
5.3.5 Troubleshooting
If a problem is suspected, measure the +12 V and Ground terminal on the
CR1000 printed circuit board wiring panel. Acceptable readings are +11 to
+14 Vdc. Use PC200W software to collect the 1-HR data table from the
CR1000 datalogger and review the historical record of battery voltage.
5.4 GOES Transmitter (Optional)
5.4.1 General Description
The High Data Rate GOES Transmitter (pn TX320) shown in FIGURE 5-2
supports one-way communication, via satellite, from a Campbell Scientific
datalogger to a ground receiving station. Satellite telemetry offers a convenient
communication alternative for field stations where phone systems or RF
systems are impractical or rendered unreliable after a tragedy to the local
infrastructure. Data transmission rates of 100, 300, and 1200 bps are
supported. Because clock accuracy is critical for GOES satellite telemetry, the
TX320 includes a robust, TCXO-based real-time clock and a GPS receiver.
The TX320 has two siting requirements for proper operation. The GOES
antenna must have a clear view of the spacecraft. The GOES antenna is
directional and should be aimed at the spacecraft; both elevation and azimuth
are unique to the location of the planet and must be set. A poorly aimed
antenna will cause a drop in signal strength or possibly prevent successful
transmission.
For more information on the TX320 and antenna siting, go to our website at
www.campbellsci.com , enter the “TX320” in the “Search” box, and go the
equipment manual. The TX320 manual is also provided on the ResourceDVD
which ships with the RAWS-F.
The spacecraft specific DCP-Setup parameters for the GOES
transmitter must be entered in the CR1000KD menus for the
TX320 to work properly. NOTE
