Steve and I paid a last visit to Marshall today.
Steve replaced the power supply we were using and changed some settings on the Victron, which restored power to the DSM. The new power supply is in the corner of the job box to protect it since some parts aren't shrink wrapped.
I updated the static IP configuration on the dsm and the tower ubiquiti once they were back on. The dsm can now connect to the outside world and the dsm and both ubiquitis are accessible from the ucar network. (See post about networking for more details). I also need to check if these are accessible from everywhere, or just on the ucar network.
I am working on getting dsm dashboard running, which should eventually be accessible at tt.ucar.edu. For now ncharts is running on datavis-dev.
Went out to Marshall this morning to finish setup (we thought). Took care of all the things we had noted we still have to do and tried to set up networking. See Steve's comment on last blog post for more details. Here's a pic of our ubiquiti and POE injector waterproofing setup at the pedestal:
Back at FL noticed that when I'm not on the same subnet of the UCAR network I can't get to the dsm or ubiquitis, because I had guessed wrong on the gateway IP and default DNS settings.
Went out again this afternoon to finish setup (we thought). Upon getting there discovered there's no power to the dsm, culprit most likely is the power supply we're using. We had noticed the battery voltage was just 11.4 when we were out there this morning, so they must be all the way dead. We didn't have any job box keys (oops) and we were running short on time so we didn't do much troubleshooting. The pedestal ubiquiti was still powered so I tried setting the gateway IP and DNS to the gateway I got from my laptop's DHCP connection to UCAR Internal at the site (still haven't heard anything from NETS about what I should be using). Once that was done the pedestal ubiquiti can access the net, and back at foothills I can get to it over ssh and even browse to the web interface!
We're heading back to Marshall tomorrow morning to figure out a new power supply situation and make the IP configuration changes to the dsm and tower ubiquiti once they're back on...
Steve and I took a short trip to Marshall today, primarily to meet with NETS about networking for the ISFS tower. We worked out that they will activate a port for us in the further-out pedestal than the one we were looking at, and will leave a cable for us to set up the ubiquiti with on Thursday. We also discussed networking for ISS some, and decided the solution that will probably work best for the MISS trailer and iss5 is to set up ubiquiti links to the pedestal near the HAO trailer. Once we're ready to do that we'll let them know and they can turn on a port.
After that we took a quick stop at the tower. We brought out a good battery for the generator, but haven't run it yet since we still haven't gotten gas. Steve added waterproofing to the connections between extension cords and I got the MAC address of the dsm so we can get it a static IP. We tried a new USB cable to the power monitor, which now shows up as a USB device on the dsm and is giving data. However, now we're having problems with the serial board blowing fuses, so I couldn't check the rest of the data. We will need to bring fuses on Thursday so we can do more troubleshooting. We mounted the ubiquiti at the tower, pointing toward the pedestal, but haven't tested that yet (waiting on other ubiquiti and static IPs).
To do on Thurday:
- Gas for generator
- Mount ubiquiti at pedestal, mount waterproofing box for POE injector
- Set static IPs for ubiquitis and DSM (assuming I have heard back from CISL)
- Check ubiquiti connection (looks like line-of-sight won't be a problem)
- Lower tower (once we have gas in generator) and:
- Replace tape w/ bulgin caps on EC100 boxes
- Remove tennis ball
- DSM serial board troubleshooting. Bring some fuses and maybe try unplugging sensors one by one to see when it fails.
Steve and I went back to Marshall today to address some of the problems we found yesterday and fully raise the tower.
We started by pivoting the tower back down. The battery on the generator still wasn't charged enough to start it, so we used one of the batteries from the job box. Steve brought the generator battery back to the lab to charge it. When we went to undo the bolts holding the tower vertical, the tower kept tilting as we loosened the bolts, and when we removed the bolts entirely the tower settled a couple inches out past where the bolts had been holding it. Pretty unsettling:
Steve could pivot it more upright, which means the limit switch was no longer engaged, and then we pivoted it down.
We switched the barometer cabling so it's measuring at 7m, added a quad pressure port, and covered the pressure ports and bulgin ports for the barometers on the other EC100 boxes. I swapped out a 15m bulgin for a 5m bulgin for the EC100 at 27m, and we rerouted the sonic and barometer cabling to run across and down through the rings instead of down the leg of the tower. We also flipped the plate the lowest EC100 is on, since the hook on the back looked like it was touching some of the cables in the tower. Currently that plate is just being held on with zip ties:
With that done we pivoted back to vertical and raised the tower all the way, successfully this time. Steve adjusted and tensioned the guy wires and I tidied up the bulgins now that the tower's fully extended. Everything save the power monitor was giving good data.
I took a look at some networking options since we were still waiting to hear back from NETS. The pedestal by the HAO trailer has 4 open ethernet ports, but none of them seem to be active. The pedestal near the snow gauges (that Steve looked at earlier) had 4 or 5 open ports, and when I connected my laptop to one of them I could get an IP address using DHCP, so the port must be active.
We also plugged in the USB cable from the power monitor, but couldn't get it to show up as a USB device on the DSM, though we tried a bunch of different ports. I can use the Victron app to connect over bluetooth, so hopefully it's just something wrong with the USB cable.
Steve flagged the power cable as well.
We lowered the tower before we left, but left it vertical. We loosened each of the guy wire turnbuckles by 3 turns before we lowered the tower. They probably would be fine left this way, so we installed anti-twist cable ties on the turnbuckles.
Misc notes/to do:
- Job box is now locked, bring keys if you want to get into it.
- Generator is almost completely out of gas! It'll need to be refilled before we can run it again.
- Bring the (charged) generator battery back to the trailer and reinstall it.
- Remember to take the tennis ball off the lightning protection next time we pivot the tower down (oops!)
- While removing the tennis ball, cover the 2 unused nanobarometer Bulgin connectors with caps (we didn't have any – just used tape)
- Try a new USB cable for the power monitor
- Note that the guy turnbuckles fall off of the large D rings, and may bind when next raised. CHECK THEM when near the top of raising. Probably should secure them in place with cable ties.
- Networking!
Yesterday Steve, Dan, and Chris sited and leveled the tower. Today we added the generator, instrumented the tower and radiation stand, pivoted it to vertical, and did a partial test of raising the tower. When we had raised the tower partway we realized that some of the zip ties we used to run cables down the tower got in the way of raising it completely:
(A little dark, but cable ties around the leg of the tower get snagged by the next section in when raising. We left the tower partially extended temporarily and powered up the DSM to check sensors. Everything was giving good data, except the power monitor, which we haven't set up yet. After that test we retracted the tower and left it vertical until our next visit. The DSM is still running and saving data locally, but is not on the network.
Still to do/notes:
- redo cabling from 7m EC100, send it through the rings instead of down the leg of the tower.
- The config says the barometer is at 7m but we installed it at 27m, so either change the config or switch which EC100 box the barometer cable goes to.
- Need to add a pressure port to whichever EC100 we decide to use, and cover the pressure ports on the other EC100s.
- I pinched the cable to the 17m TRH (I think) while raising it. Still seems to work fine, but I marked the point that got pinched on the cable with white tape.
- If we remember next time, we could replace the 15m bulgins with 5m bulgins for the cables to the top level, since they already have 25m bulgins on them.
- DSM dashboard only shows a blank screen.
The MISS (Mobile Integrated Sounding System) was deployed at Marshall on May 13.
It is positioned approximately 30 meters south of the sounding building and is orientated at about 285 degrees. Power is being supplied from the sounding building, but network is not yet connected. The 915 MHz wind profiler was started around 19:30 UTC (May 13) and is working well, currently recording winds up to about the 4 km level, although that will vary considerably depending on conditions. A WXT weather sensor currently positioned about 6 meters south of the trailer is also collecting data. The system includes a GAUS sounding rack capable of tracking RS92 radiosondes, although that is not yet running.
