Summary: Downgraded LI-7550 boxes, swapped 7500 heads, still trying to get of Tower co2 profile to run, still trying to get tower computer to run, still trying to get well and zcam 3 to run.

I arrived about 10:30 with Siyan. It was super clear, sunny and warm with little to no wind. The Sierras were visible all the way out from the Delta and I could see Mt Diablo clearly from the Tower. Puddles on the road and the ground is damp. We saw a pickup with trailer and four wheeler head west on the road. Looked like the road has seen quite a bit of traffic recently. One mutant oak tree near Mr Tonziâ€™s old house is starting to put on leaves.

I downgraded the firmware of the Tower 7550 sn AIU-1866 and Floor 7550 sn AIU-1869 from v8.7.5 to v8.5.0. This was to standardize our systems. All the Delta systems went back to v8.5.0 because of problems with extra junk columns showing up when a 7700 was connected in v8.7.5. Then swapped heads for calibration. Tower: sn 75H-2668 coming off and sn 0041 going up. Floor: sn 1594 coming off and sn 0042 going up.

Tower:
V8.7.5 2668: 410ppm CO2, 331mmol/m3 H2O, 14.4C, 99.8kPa, 101.3SS
V8.5.0 2668: 410ppm CO2, 347mmol/m3 H2O, 14.5C, 99.7kPa, 101.3SS
V8.5.0 0041: 412ppm CO2, 290mmol/m3 H2O, 13.8C, 99.7kPa, 100.7SS

Floor:
V8.7.5 1594: 408ppm CO2, 330mmol/m3 H2O, 17.9C, 99.8kPa, 103.2SS
V8.5.0 1594: 408ppm CO2, 308mmol/m3 H2O, 17.6C, 99.8kPa, 103.3SS
V8.5.0 0042: 409ppm CO2, 306mmol/m3 H2O, 17.9C, 99.8kPa, 99.5SS
I check clocks and columns and all seemed well. There seems to be a drop of about 30mmol/m3 in H2O related to the change from v8.7.5 to v8.5.0. I have seen something similar in the Delta sites. Hard to tell if it is real and should be countered by calibrations.

I tried to fix the old Tower co2 profile by swapping out the CR10X silver box: sn 47253 went in and sn 20138 came off. After reloading the program it seemed to be function although I did not check the final storage data. The LI-820 was give bad readings. I cleaned the path and was able to calibrate it, but the values still seem to bounce around +-20ppm which is more than normal I think.

I added a modem to the LattePanda but there was no power. The plugable terminal where the power converter was plugged in had no voltage as did the two empty connectors downstream. Maybe a wire broke but that seems odd. I connected the power converter to the black screw terminal and it seemed to power up with only the positive lead connected. There must be a ground somewhere upstream. Unplugging the serial line to the co2 profile system seemed to remove the ground. Still, the power converter was getting really hot and browned out. Itâ€™s supposed to be to handle 3A and the solar charge controller was only showing about 0.5A at 24V with the screen and LattePanda on. Iâ€™m not sure whatâ€™s happening here but I unplugged things until I do some testing in the lab.

Z-cam 3 connected to the CR200 still didnâ€™t take any photos. I might be toggling a control port instead of the SW12V port. But might be good to have a CR10X ready to swap in next time.
