Hi,
So to repeat what we just spoke about on the phone, to snapshot into universe 2 you will have to use connection B as the input. For the output it doesn't matter, as you can select which universe should be output on which port.
The snapshot command will snapshot all input to the corresponding universes.
Current firmware version of the QuadCore is 1.35 if you use vManager version 1.4.54
Greetings,
