The output format of the 3 Licor 7500s that were re-installed today had been reconfigured during the calibration to output in verbose mode, with labels. To save archive space, we reconfigure the units for a more terse output, without labels, at 10 Hz.
To setup the Licors to output the format that our data system expects, do the following:
- shut down the data process
adn - run minicom on the Licor port
minicom ttyS2 - If the baud rate agrees with minicom (9600) you should see the default Licor output
- Send a break character, by doing "control-A f" from minicom
ctrl-Af - Send these strings to the Licor:
(Outputs (RS232 (EOL "0A") (Labels FALSE) (DiagRec FALSE) (Ndx FALSE) (Aux FALSE) (Cooler FALSE) (CO2Raw TRUE) (CO2D TRUE) (H2ORaw TRUE) (H2OD TRUE) (Temp TRUE) (Pres TRUE) (DiagVal TRUE))) (Outputs (BW 10) (RS232 (Freq 10.0) (Baud 9600)))
- You won't see much output, perhaps just some changing numbers on the right-hand-side, since the Licor is sending just a line-feed termination and no carriage-return. You can turn on line-wrap, with "control-A w" to see the data stream from side to side:
ctrl-Aw - Exit minicom with control-A q
ctrl-Aq - restart the data process:
aup - check the Licor data (may take 30 seconds or so for the data system to open the port):
rs 2 - The data should look like:
248\t0.06460\t12.4193\t0.01218\t81.586\t16.10\t76.1\t\n 248\t0.06462\t12.4179\t0.01207\t81.459\t16.11\t76.1\t\n
- Exit rserial with control-D
ctrl-d
