You can use telnet to connect to a VideoHub and output the mapping but I wanted something that looked more like the way audio software like x32 or Dante shows a matrix.
So I have written a PowerShell script that outputs the current configuration as an Excel file
I have created an exe version that is very simple to run. You just have to have Excel installed on the same computer
The Exe defaults to assuming the local PC is a server for a studio hub. Otherwise you can add an ip address on the command line to connect to a smart hub.
You only need .Net 4.6.1 runtime and Excel 2010 or better, I think (keen for someone to test for me)
Remember to unblock the file after downloading.
If you want to see or play with the source, download the script from https://gist.github.com/imorrish/b03fc2e5fbd3fc64de1d010ac79ad0b5
I will add lock information as well as Video Monitor outputs for hubs that support that.
