RAWS-P Remote Automated Weather Station
5.5.2 Wiring
The CR1000 Keyboard/Display (pn CR1000KD) connects to the CR1000 PC
board “CSI/O” 9-Pin connector using a standard serial cable (pn 10873) that
ships with the RAWS.
5.5.3 Troubleshooting
If a problem with the CR1000 Keyboard/Display is suspected, the CR1000KD
may be checked by connecting the CR1000KD to the CR1000 PC board 9-Pin
“CS I/O” connector using our 9-pin serial cable (pn 10873). The CR1000KD
display should be visible. Check the CH100’s ON-OFF switch. If the display
is not visible, check the CR1000 wiring panel for 12 volt power. If the
CR1000 is unresponsive to CR1000KD key strokes, there might be a problem
with the CR1000 datalogger. If problems persist, try a substitute. Obtain an
RMA number before returning this equipment to Campbell Scientific for
repair.
Consult the CR1000 manual for more information. NOTE
5.6 CR1000 Datalogger
5.6.1 General Description
The CR1000 shown in FIGURE 5-4 provides sensor measurement,
timekeeping, data reduction, data/program storage, and control functions. The
CR1000 includes 2 Mbytes of memory for data and program storage. A
lithium battery backs up the RAM and real-time clock. The CR1000 also
suspends execution when primary power drops below 9.6 V, reducing the
possibility of inaccurate measurements.
