460 +The first thing to do is to register the nodes in the system, so the software can recognize them. To do this, go to the folder where the “SmartSoloApps SoloLite” was installed. 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.
461 +
462 +[[image:1705195543887-977.png]]
463 +
464 +
465 +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.

470 +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.
