RAWS-H Remote Automated Weather Station

5.5.2 Wiring

The CR1000KD connects to the CR1000’s CS I/O connector using the 10873
cable that ships with the RAWS-H.

5.5.3 Troubleshooting

If a problem is suspected, the CR1000KD may be checked by connecting the
CR1000KD to the CR1000 PC board 9-Pin “CS I/O” connector using the 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.

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.
