49 +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:
50 +
51 + - Place the node on the harvester gently, then firmly press it down onto the pins
52 +
53 + - 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.
54 +
55 + - 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 eachother
56 +
57 + - Nodes will likely not show up in the order that they should, though this is not an issue. Eg, a node in slot 6 on the harvester may show up in port 13 in the SoloLite software

480 -The** 5 Hz nodes** are susceptible to horizontal noise due to the placement of geophones in the units, **but this can be mitigated by completely burying the units flush with the ground.** In the below example, the node was set on the floor of our basement set on its plastic carrying case support. As such the amount of horizontal noise noticeably increases above ~~ 10Hz.
