Only the 3 used signals on one side, and the 5 ground pins on the other (check the first attachment)

This way, you can connect the ribbon like on the second attachment.

I hope it's not too obscure
Perfect! I'll work with this ...

Not sure what you were asking here
No, me neither (not knowing what I'm asking), but I have seen 'discussions' on whether to go with synchronous or asynchronous connections from Cronus to dac. But I'm happy with your answer, and will try to get it to work as you explained it

Ah ok, those discussions were about ESS dacs like the TPA Buffalos.
(which can use async reclocking with its own clock, or just sync).
The DDDAC is a pure slave dac.

Feel free to ask when you'll be at it (except about BBB which I don't have...)

So in this way all the pins/lines get exactly where they are supposed to go? That is fantastic!

That's it.

But beware the VDD connector on the DDDAC header.
3.3V or 5V on the wrong pin could possibly damage the Cronus.
You can even cut the pin on the DDDAC board to be safe.

Thx

EN on = Hermes is powered on
others are "unused", you can control them if you want:
- P9_11
- P9_12
- P9_13

Also there are 3 pins available for push buttons on J_RE connector, pulled up to 3.3V::
- P9_16
- P9_15
- P9_23

Thank you Miero,

I am asking because on many photos I see all 4 LED on. On my Hermes LED label "2" is not working (double checked orientation and solder joints). I suspect the small IC labeled QA3 has 5,1 V in but only 0,39 V out. Where the other IC (QA1, QA2, QA4) have 5,1 V in an 5,1 V out. As I do not know what type it is I do not know if it is defect or disabled (in software)?

Does someone know replacement type?

Thank you

Branko
