Hi,

I am wondering how to clock this setup consisting of 2 computer in different rooms each using an UFX II (I call them first and second):

The 1st UFX II acts as the Main clock.
It connects via:
USB to Computer 1
ADAT 1: to an old Fireface 800 (in standalone mode, to extend the analogue In/Outs)
ADAT 2: to a 2nd UFX II (via ADAT 2)

The 2nd UFX II is receiving the Main Clock from the first UFX II through ADAT 2 via an Appsys Cat5 Extender (so far so good...).
However, we are also extending the 2nd UFX II through ADAT 1 with an ADI-8 QS. That ADI-8 QS is blinking and there is a clock issue. It seems that the 2nd UFX II can not pass on the clock it receives from the 1st UFX II to the ADI-8 QS via ADAT.
If I set the 2nd UFX II to internal clock then the ADI-8 QS is in sync, but of course I loose sync to the 1st UFX II then.

How can I solve this?

1) Would a Wordclock connection from 2nd UFX II to the ADI-8 QS solve this or would it still not be able passing on the clock it receives via ADAT 2 from the 1st UFX II?

2)
I suppose a word clock cable from the 1st UFX II to the ADI-8 QS should definitely work, but it is quite a long distance and the ADAT runs smoothly via the Ethernet, I am looking for a different way than connecting a super long Wordclock cable between the two.
So if 1) does not work: Would an ADAT splitter be the solution then, going into the AUX In of the ADI-8 QS?

Hoping for some good advice, thank you!
