Also there is feature which can automatically do all that. It can be found in Base/Rover setup, you should connect to your Base receiver and go to "Remote Base" -> "Sync DPOS tasks" screen and push "Start synchronization". It will compare time ranges of all Base files and Rover files in current project, find intersection and try to create DPOS tasks if not exist (including downloading GNSS file from Base, creation of Base point, attaching files, etc).If you are using your T2 and your 2 LS's just start it with one LS and on the second make sure the setup for communication is the same as the 1st LS. Then when done download with LS 1 and then transfer the base file to LS 2. In the points screen use the menu button to recover base point, attach gnss file, and recover dpos session.
