18 -We recommend that the SP 16HR-3C be set to a gain of 24db 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). These are what we use for our internal experiments.
19 +The nodes must be programmed in the SoloLite software prior to use. Screenshots for the short period 16HR-3C and broadband BDC3-5 are shown with our recommended parameters.

20 -**Note that this gain must be removed when exporting to miniseed, **otherwise amplitudes will be a factor of either 15.84893192 (24db) or 2 (6db) too high. We also recommend disabling bluetooth to increase battery life, and to enable "FIFO" mode just in case old data is still present on the units and you run out of space (although it is unlikely you will go over 64 Gb for one deploy). If using the "timed turn-on" option, please be aware that **the units will not begin recording until they have acquired a GPS lock**, which may nor occur if they are buried too deeply or have very poor sky view.

24 +
25 +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.
26 +
27 +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.
28 +
29 +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.
30 +
31 +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!**
32 +
33 +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.
34 +
35 +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.
36 +
37 +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.
38 +
39 +Bluetooth (BB nodes only) should be turned OFF to conserve power.

243 +SmartSolo provides the following powerpoint for SmartSolo node programming and operation. Note that ANSIR only uses a portion of their process for our own uses: [[https:~~/~~/nappe.wustl.edu/smartsolo/files/smartsolo_online_training.pdf>>url:https://nappe.wustl.edu/smartsolo/files/smartsolo_online_training.pdf]]

245 +== Connection tips: ==
246 +
247 +Connecting SmartSolo nodes to their harvesters and having SoloLite recognise them can be a bit tricky, here are some tricks to help register and program them easier:
248 +
249 +* Place the node on the harvester gently, then firmly press it down onto the pins.
250 +* 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.
251 +* 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.
252 +* 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!

274 +== File structure ==
275 +
276 +There are essentially three main folders where relevant PROSPECT and PROJECT DATA is stored. Individual projects will be found as subfolders in these.
277 +
278 +=== SOLOLITE ===
279 +
280 +This folder stores SoloLite config files and parameters. Nothing too important stored here, you can always start over and re-create this.
281 +
282 +=== DCCDATA ===
283 +
284 +This folder stores the RAW data you have harvested from the nodes. The data will still be on the nodes (unless you erased it) in case of emergency, but regardless, this is the folder you want to back up and save somewhere.
285 +
286 +If you had a weird time harvesting a node, you can always manually copy it as if it were a USB stick and place it into this folder manually. The structure is: //C:/DCCDATA/prospect_name/project_name/SERIALNUMBER/label(usually a timestamp but can be anything)//
287 +
288 +Then in the SoloLite software, go to tools > Reanalyze Seismic Data
289 +
290 +=== SOLODATA ===
291 +
292 +This folder stores **exported** (e.g. miniseed) data. It is structured similarly. If your DCCDATA is intact, this can always be re-created if need be.

If data is headed to AusPass, we prefer to invert the IGU-16HR 3 Z channel data manually rather than in the SoloLite software or inverting the response metadata. **The BD3C-5 data does not require a polarity inversion.**
322 +
323 +== 18 Leap Second bug ==
324 +
325 +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 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.
326 +
327 +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.
