Summary: Swapped 7500s, Tried to restart co2 profile, Cleaned up Tower computer box, new serial multiport, added towermet tz6 to daily data

I arrived about 10:30 with Siyan and Elke. It was clear, sunny and warm with a nice breeze. There were lots of flowers, but the grass has begun to turn yellow. I did not notice a change in the pond level. Cows are around.

I swapped the tower 7500: sn 0418 came off and sn 0041 went on.

I cleaned the radiometers.

I tried to get the CO2 profile system going again. Loggernet reports control port four as stuck on, but it does not actuate the solenoid. I disconnected the port from the hardware, re-uploaded the program and even reloaded the CR10X OS. Nothing seemed to fix the problem. I think the data logger needs to be swapped out. I left the system off.

I rearranged the computer box on the tower. I put in an eight port Quatec serial to USB box. This required enlarging the cable hole in the bottom of the box to move the cables to the left. And I removed the old computer lid that was glued to the bottom of the keyboard tray. The box is much neater now.

I used the old Ethernet cable from the old web cam to connect the 23x at the top of the tower (tz6) to the computer. I setup up the software to send the tower met data to Berkeley daily. It all worked while I was there. The modem reported less than 1MB of its 10MB limit used.

The Ethernet to the Phenocam was not working after all the box cleaning. Restarting the Phenocam seemed to fix the problem.

While Siyan and Elke went to Vaira. I ran a new line of Ethernet cable to the soil moisture 23x. I put this line is plastic pipe. Eventually I want to run the power line through the pipe too and use a couple conductors of the Ethernet to control the nearby z-cam. I started running wires to connect the floor met sensors to the soil moisture 23x (tz3). I might have to extend the HMP45 wires. The barometer can be moved to the 23x box.

I cleaned the z-cam windows.
