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.
5.6.3 Troubleshooting, CR1000 Keyboard/Display (part #CR1000KD)
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 the 9-pin serial cable (part #10873). The
CR1000KD display should be visible. Check the CH100 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, then there might be a
problem with the CR1000 datalogger.
5.7 CR1000 Datalogger
5.7.1 General Description, CR1000 Datalogger
The CR1000 shown in Figure 5.7-1 provides sensor measurement,
timekeeping, data reduction, data/program storage and control
functions. The RAWS CR1000 datalogger 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.
