Gordon and Tom worked on improving the ethernet connectivity. Gordon opened the low DSM and discovered that the ethernet surge protectors for the connections from the mid and high DSMs were extremely hot.
12:13 Gordon pulled the fuse on the eth1 port in the mid DSM
12:17 Gordon removed the fuse on the eth1 port in the high DSM
(I removed the fuses because I didn't know which jumper controlled the output voltage on these eth ports.)
From the low DSM, Tom pinged, in succession, the high DSM, mid DSM, the router (192.169.0.5), and google.com. In all cases, 50 pings were returned with no missing returns. At the same time the ethernet surge protecters in the low DSM cooled appreciably. Vmote (3,19) at the high DSM now reads a voltage of 12.22 V.
Gordon added an ethernet surge protecter to the cable between the ethernet switch and the router now at the top of the tower.
Previously we saw about 10% loss of packets on pings to high. The CBR400 router was also not stable, frequently it would stop responding to http requests. Data samples from the high DSM over the network were being discarded because the TCP connection would not keep up.
The networking to high and to the cbr400 router on the tower now seems to be much improved. It appears that the DSMs were putting a +V on the ethernet cable and the surge protectors were trying to discharge it, getting very hot, and having an adverse effect on the comm signsls.

Gordon and Tom serviced the sensors and DSMs on the profile tower:
44m: Cleaned Licor
38m: Cleaned EC150
~36m: Cleaned K&Z 4-component net radiometer
32m: Cleaned Licor; grounded DSM; cleaned PAR; Tsfc @ -1.5 degC
26m: Cleaned Licor, PAR, and wetness sensor (splattered w/ bird crap)
20m: Licor and PAR cleaned; PAR covered in bird crap
14m: Grounded DSM and fixed usbdisk; cleaned PAR, KH2O (0.35V) and wetness sensor; no Tsfc
8m: Cleaned PAR, Licor, wetness sensor; typical splatter of bird crap
2m: Cleaned KH2O (0.35V)
There were questions about the PAR at 32 m (1036 W/m^2) and 14m (50 W/m^2), but these seem to fit into the profile of the other PAR's.

The cradlepoint CBR400 router and the Verizon modems have been working, but have some issues.
On May 27 and 28, the router would go offline periodically, and not be pingable from the local network at address 192.168.0.5 (cbr400). From the web interface (http://cbr400), System Settings -> System Control -> Advanced, I turned off "Enable Watchdog Reboot" to see if that would help. The CBR400 stayed up all night. When we arrived at the trailer (9:20) it was pingable, but the web interface would not respond.
The 3G modem has been working fine. On the web interface for the CBR400, the signal strength is typically -75 dBm, with 4 bars.
The 4G modem does not always connect. The status page shows a signal level of -79 to -84 dBm, which I presume is acceptable.
The CBR400 sends log messages to the syslog on "flux". The 4G modem is known as "WAN:9d7c85c4". The logs show "carrier reject", and that it reverts back to 1XRTT (2G):
fgrep CBR /var/log/messages | fgrep 5c4 May 28 16:45:12 cbr400.isfs.ucar.edu (CBR400-afa) WAN:9d7c85c4: Connection Change : None -> EVDO, % May 28 16:45:12 cbr400.isfs.ucar.edu (CBR400-afa) WAN:9d7c85c4: Connect Event: carrier reject May 28 16:45:12 cbr400.isfs.ucar.edu (CBR400-afa) WAN:9d7c85c4.CPPM: state=connecting result=carrier reject May 28 16:45:19 cbr400.isfs.ucar.edu (CBR400-afa) WAN:9d7c85c4: Connect Event: carrier reject May 28 16:45:19 cbr400.isfs.ucar.edu (CBR400-afa) WAN:9d7c85c4.CPPM: state=connecting result=carrier reject May 28 16:45:44 cbr400.isfs.ucar.edu (CBR400-afa) WAN:9d7c85c4: Connection Change : EVDO -> 1XRTT, %
I plan to contact Verizon and see if they can help from their end concerning the 4G modem.
Morning of May 29:
Upgraded firmware on CBR400 to version 4.3.0

Until we can get the 4G modem to do better than 1xRTT, we'll use the 3G and disable the 4G.

The cellular worked quite well yesterday, but not so hot today, frequent disconnects. I tried enabling the watchdog reset on the CBR but then disabled it again after several hours since it didn't help. The router_check.sh script on the "high" dsm is our own watchdog reset.
While on the tower, I checked the antenna cable connections at the modems, and the usb connections at the hug. All looked good.
TODO: look at the logs. Perhaps the signal levels were lower today? Contact verizon about 4G.

AP24 is on a pipe at the NE corner of the base trailer.
eante (192.168.0.80) is mounted on a T-post at pond DSM (192.168.0.101)
Gary setup the etherants at the sodar and lidar.
eantf (192.168.0.81) is at the sodar (192.168.0.91)
eantg (192.168.0.82) is at the lidar (192.168.0.92). There is also a camera at the lidar (lidarcam=192.168.0.253).
All links OK.
To view the signal levels, point a browser to eante, f or g, login to admin, usual password about sonics.
To view the signal levels on the ap24, point a browser to ap24, admin, sonics. Click on "RegTable" link on the left-hand side, or you can ssh to it and view the registration table:

From candlewood this morning around 6:45 was able to ping isfs1.dyndns.org. Later, around 7:15 was not able to ping.
On arrival at base, could not ping tower DSMs. SDF was on, but no RXF on fiber transceiver.
At tower, 10:05 CDT
Battery terminals: 12.29V
Charge controller, "solar" input: 13.21
Charge controller, load: 0V
I believe the load disconnect LED was on
TRH fans were off
As I was probing the charge controller, the TRH fans started up. Perhaps the battery/controller/charged cooled a bit since the cooler lid was open?
Measured voltages again:
Battery terms: 12.69
Charger battery: 12.88
Charger solar: 13.07
Charger load: 12.84
DSM 12.16
By looking at the archive files on the DSMs, the system has been up and down this morning:

The fiber network is up.
When the fiber was strung, we connected all 4 fibers, blue, green, brown and orange at each junction.
The first test was with the blue and green fibers, but the network would not come up. In the trailer, the SDF (signal detect fiber) would go green, but SDF at the tower was out.
Switched to brown and orange, and it is working now.
Base trailer: TX: orange, RX: brown
Tower: TX: brown, RX: orange

May 27.
Installed the soil sensors at site A (near the radiation stand) this morning. Also buried a little more of the cables near the sensors at site B (near the rain gauge).
Heights of top of each bracket WRT tower base plate. Brackets at 13.92 and 43.86 meters had to be offset a bit due to section junctions or guy hardware.

The whole tower is now dressed and running...kinda. We have all tubes and instruments running (Gordon saw 100% coming in) then we shut it down due to power. We just did a test with the batteries then we let the batteries charge off the transformer. The TRAM Trailer does have the air conditioning working but no racks are set up yet so no power has been laid out. Soil probe B is in w/ the tipping bucket and the radiation stand has been installed with no soils. Fiber has been run but not hooked up.
Kurt, Gordon and Tom will remain on site until start of project.
The radiation stand is within +/- 2 degrees of true E/W and has 4 Kipp & Zonen broadband radiometers (incoming and outgoing long and shortwave radiation), the SPN net radiometer, and a leaf wetness sensor. Radiometer levels have their bubbles within the 'bullseyes'.
The whole tower has all instruments on it and the cables/tubes are dressed. We have a couple of tubes that are low that need to be strung and the lower dsm to be hooked up and then we can have Gordon test all instruments while I am here. We still do not have power to the tower but now that ACDs gear is loaded and the trailer is put into it's spot we can start hooking up transformers and run power to tower. We can do testing off of batteries for today but we should have power going soon to the tower.
Gordon and Tom have arrived and they found the tower.
The inlet on the tubes are hanging just by the Licor mounting bolt. It seems to be far enough away from sonic/licor and pressure port. Tom will have the final say on location today.
Things to do:
Soils/radiation stand (tom)
lower dam (chris)
tower power(kurt)
fiber (john/gordon)
pond & lidar communications (john)
We have instrumented the tower!!! We are all exhausted from todays setup.
We have all levels up except for the four component radiation and the canopy par wand. These should be done tomorrow.
Trailer power is up and running. The power to tower is not, but this is waiting on ACD due to where the trailer will reside.
Things to do:
Four component on tower.
Par wand at canopy height.
ACD tubes installed.
soil probes installed.
power to tower.
ACD loaded.
We had a great day today.
We had a state forest servicer person get a rig to move our Base Trailer to the pole barn. It is in place and set up. WAHOO!!!! This means no Black Warrior or Electrician needed.
The power cable has been drug through the woods and is in place. No power yet (need breakers) but it's at least there and ready to hook up.
We also have dressed the High dsm levels and looks great.
Soil and radiation spots have been picked but not installed. Waiting on tower to be dressed while Ned is here.
TRAM trailer has been moved to accommodate ACD. We are having them directly transfer equipment or forklift rental. I have been talking with Peter and Andrew on this transfer.
Things to do tomorrow:
Dress the rest of the levels on the tower.
Hook up power to trailer and site.
Communications to Pond and LIDAR.
Soils installation
Help ACD with equipment transfer.
GO TEAM!
