33 -FIFO (first in, first out) data mode is safest as this will overwrite old data in case you forgot to clear the storage. At <= 250 hz you can fit 4++ months of data on these, shouldn't be an issue.
34 -
35 -Note that the samplerate is instead given in sample spacing, in milliseconds. 4 ms = 250 Hz, 1 ms = 1000 Hz, 10 ms = 100 Hz, ad nauseam.
36 -
37 -Be sure to set the channel types to Seismic and the gain appropriately. For active source (i.e. explosions) you can leave the gain at 0, but for passive experiments some gain is purported to be helpful (although we have found this to be somewhat negligible). We can confirm that 6db for the broadband nodes and 24db for the short period works well.
38 -
39 -If you want recording to begin immediately, ensure that begin date is in the past by at least a few days. If you prefer to have a timed turn-on, then set the times as needed. **Be warned that recording will not begin until a GPS lock is achieved, so if you set it to a future turn-on but bury it too deeply, it may not record!**
40 -
41 -In newer versions of the software there is a "power consumption" setting.. we are no sure what this does exactly, but the manual says it gives life a "boost" at the expense of about 3 db of resolution. Until this can be quantified a bit better it is not recommended.
42 -
43 -Storage type can be DLD (proprietary) or Miniseed. We assume the software works best with their proprietary format so prefer not to risk any issues. You can export to miniseed later.
44 -
45 -GPS is best set to cycle mode (e.g. once per hour) instead of constant "always on". The clock drift on these are almost nil even if there is no sync at all, so it's best to conserve power.
46 -
47 -Bluetooth (BD3C-5 only) should be turned OFF to conserve power.
48 -
49 -We recommend that the 16HR-3C be set to a gain of 24db for passive experiments and no higher than 250 Hz sampling rate unless there is an explicit reason to do so. The BD3C-5 should be set to a gain of 6db (which is the maximum allowed) for passive experiments (or 0 db if active).

AMF Magnetics is a good retailer, and [[this item>>https://magnet.com.au/collections/shop?q=23012B]] seems to work well. It is also advantageous to use smaller magnets and store/carry them individually in your back pocket (as well as stick them to various places in your field vehicle, etc).
69 -
70 -== Animal-Proofing ==
71 -
72 -We have experienced interference from animals (foxes, dogs, goats) digging up and carrying nodes off for tens or hundreds of metres. It is helpful to minimise human and food smells (particularly on the rope handles) when working in areas where this is a risk. Or, wipe down affected nodes with 50-80% methylated spirits if extensive handling can not be avoided.

271 -
272 -* Place the node on the harvester gently, then firmly press it down onto the pins.
273 -* Place all nodes onto the harvester before trying any troubleshooting, as they may not show up while the SoloLite software is running. Once all are connected, try restarting the software for them to be recognised.
274 -* If a node is refusing to connect, try it with another slot. It is easiest if you place all 16 nodes on the harvester, and swap any nodes that refuse to connect with each other.
275 -* Nodes will likely not show up in the order that they should, though this is not an issue. E.g, a node in slot 6 on the harvester may show up in port 13 in the SoloLite software. Annoying, but it doesn't matter so long as you keep track of what's been harvested!

353 -Not so much a //bug// as much as "a thing that can happen if your SoloLite installation is corrupted". If you notice your data has large constant time offsets, you should suspect that the number of leap seconds has not been accounted properly. There is a file "smartsoloconfig.xml" that needs to be present in "C:\SmartSoloApps SoloLite" (e.g. the main program directory) that dictates the leap second offset for the last two data ranges. Since 2017-01-01, this is 18 seconds. At some point in the next few years it will be 19 seconds.
354 -
355 -If this file is missing, just create a new one structured like so, name it "smartsoloconfig.xml" and put it in your main program directory. Then, Reanalyze your data (tools > Reanalyze seismic data) and your data should have the correct time. You can also do this manually, if you want. The offset is 18 seconds precisely.

As such the amount of horizontal noise noticeably increases above ~~ 10Hz.
344 +Both nodes take about 6-8 hours to charge from flat and hold their charge reasonably well, however you may benefit from a "top up" charge immediately prior to deploy. The instruments should last around 30 days per cycle (recording at 250hz) with GPS on cycle on and bluetooth disabled.

434 +
435 +

Then right-click the deviceconfig.exe program to “run as an administrator” and save the file to the directory of “deviceconfig” (snapshot below). Note that to avoid registering the same node twice, you can simply replace the file each time you do the registration.
437 +
438 +[[image:1705195543887-977.png]]
439 +
440 +
441 +Then open the “SoloLite” software, and just go to “File” to make a new project. In this case, you do not need to find the exact 16 nodes that were grouped for script writing. Do not worry about the settings for the seismic recordings for the next window to pop up, as the only way to reset the instruments (e.g., sampling rate, gain etc) is to write script to re-program them.
442 +
443 +[[image:1705195543890-537.png||data-xwiki-image-style-alignment="center"]]
444 +
445 +
446 +Once you create the new project, your Data Transfer View panel on the bottom right of the window will show these nodes that have properly connected to the data harvest, including series number, data size etc. It is okay if the “Prospect not matched”, which simply means the project you just created does not match the one you made to program them. Simply select all these nodes, and right click to “force download”, which will initiate the downloading process. Once they are done, you will see new folders created for each slot at your Downloaded Data panel on the top left of the window.
