26 -The nodes must be programmed in the SoloLite software prior to use. The screenshots below show our recommended parameters for the 5 Hz (16HR-3C) and 5 second (BDC3-5) nodes.
19 +ANU recommends that the SP 16HR-3C be set to a gain of 24db and no higher than 250 Hz sampling rate. The BD3C-5 should be set to a gain of 6db (maximum allowed). These are what we use for our internal experiments. **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.

32 -
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).

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.

78 -Both the 5Hz IGU-16HR and 5s BD3C-5 can be optionally powered via external battery via either a replacement bottom half (the 5Hz nodes) or a battery cable accessory (BD3C-5) using standard lead acid batteries from 9-36v. We have done preliminary testing at 250 Hz with a 12v battery:
79 -
80 -- BD3C-5: ~~2 days of recording per 1 Ah
81 -
82 -- IGU16-HR 3C:  ~~3.5 days of recording per 1 Ah
83 -
84 -- IGU16-HR 1C: ~~7 days of recording per 1 Ah
85 -
86 -Of course, these can also be fit with a solar panel & charge controller which would then theoretically keep them going indefinitely (limited only by the disk storage, which at 250 Hz could be on the order of 12 months).

274 -* Place the node on the harvester gently, then firmly press it down onto the pins.
275 -* 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.
276 -* 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.
277 -* 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 -== 18 Leap Second bug ==
354 -
355 -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.
356 -
357 -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.

One has to be careful with how polarity is handled between groups as well, and if one is working in integer counts (the ANSIR default) or mV (unclear why anyone would use this as it makes file sizes enormous). The response information published below is in **counts** and seems to fit well in huddle tests. Note that the response is the same for all channels and all units (e.g. there are no bespoke calibrations!), all appear to be sample rate insensitive, and the IGU data has been inverted (multiplied by -1) as described here: [[5Hz Node Polarity Issues>>https://auspass.edu.au/xwiki/bin/view/Data/AusPass%20Data/#HSmartSoloNodePolarityIssues]]
