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. 262 +* Place the node on the harvester gently, then firmly press it down onto the pins. 263 +* 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. 264 +* 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. 265 +* 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! 156 156 157 -[[image:1705195543887-977.png]] 158 158 159 159 160 - Thenopenthe“SoloLite”software,and justgo to “File” tomake anewproject.
