Frequency measurements with different inputs

[Rufus McDufus]

No problem of course Rufus! I wasn't sure as well and doing the same as you (looking at some pictures) it looks like I wasn't completely right either. It looks like one of the two toslink inputs is on the mainboard (the 3,5mm jack one) and the other one is part of the DUET card (which is the replacement card for the former HDMI input card) or maybe the mainboard below. Also I was thinking, DUET perhaps stands for Devialet/Digital USB Ethernet Toslink proving my theory wrong again.

And I am even more confused now; I know AIR Wifi is on a separate card and if I remember correctly AIR ethernet couldn't/wouldn't work without that AIR WiFi card present so the "routing" of signals is very unclear to me. I hope the specialists at Devialet can and will do the 100% right "deducing" in troubleshooting this issue for Divasson!

Ah, thanks for clarifying what the DUET card is!
