Here are some presentations on the setup of the PiGate, as well as a couple of videos that were made at the Digital Communications Conferences in 2016 and 2017.
These are a little old, and don't reflect the changes in PiGate 2.0, but they are still useful.
To the right are a number of "training" videos that I made to help explain the new PiGate 2.0 user interface. Watch these videos in order to learn some of the features of the new interface. Also download and read the documents, which have more details.
