Relatively calm day.
After checking station statuses, we looked into why the DSMs are so often writing more than two files per day. The following are some observations, and a potential fix.
- The file rewrites seem to be caused by events that disconnect and reconnect the USB devices. These seem to originate from the Ethernet. Steve can provide the exact error message
- The DSMs that reset the most are lconvm, relm, and relt. This is based on looking at the files from the past 5 days (10/2 - 10/6).
- DSMs that reset the least are lconv1, lconv2, lconvt, p1-thru-p6, uconv2, and uconvm.
- One possible cause is that high traffic on the DSMs with network switches causes usb reset
- Potential fix: Steve looked up the problem online, and found a potential fix is to configure the Ethernet switch to work at USB 1 speeds (forget the exact syntax or config file that needs editing, but that's basically what it does). We've tested the fix out on P6, just to see if it causes any adverse effects. It doesn't. Gary, should we try this on the problem DSMs?
We went to the U of IL Atmospheric sciences picnic, invited by Francina who didn't attend.
I took three soil samples for moisture measurement.
- Release tower cornfield: tare weight = 21.30g, wet soil weight = 134.1g. tin 4
- Upper Conv grass: tare weight = 21.45g, wet soil weight = 130.62g. tin3
- Lower Conv soyfield: Tare = 21.26g , wet soil weight = 134.55g. tin2
Steve made theodolite measurements of Init and Release tower sensors.
Dinner afterwards with Francina at the Sunsinger. It isn't cheap, but has a decent wine selection
