Hello MC

Sync\lock keeps changing all the time on all adats. probably when i took the picture it was on lock.
anyway it is not lock, it keeps changing all the time.

Setup:
Installed both cards using official drivers.  OS windows server 2008r2

On the picture you can see the connection between the cards.  The cable connected between themself via 3 pin male\female.

What other information is missing?

Thanks

Hi Maxis,

When you have correctly configured clocking between the RayDAT cards, and everything else connected to them, all the inputs in use will show "Sync". The fact that it keeps changing only indicates that you have an incorrect configuration.

In a digital system, only one device can be the "master". This device will use it's own internal clock, then you need to set every other device in the digital system to follow the master clock.

If you need more assistance you will need to be very specific about each connected device, the individual settings (especially clock settings), and how everything connects.

We do not understand what you talk about:

> On the picture you can see the connection between the cards.

No I can't. Worst photo ever.

>  The cable connected between themself via 3 pin male\female.

???? Does that refer to AES? Where are all the ADAT I/Os going to and coming from?

This is fine. The cards are synchronized. But the other devices you are connecting to the RME cards are not synchronized.

We still need to know what connects to the ADAT ports, and the clock settings of these external devices.

There's your problem. This won't work. Without an actual external sync source, the "external" switch will do nothing. You will need physical Word Clock sync in your setup... No other way to have all the converters run in sync. And not at all an RME problem, if I may say so.
Configure/choose one converter as master, and sync all the others with Word Clock. And the cards to ADAT.

Your problem is that you do not seem to have the optional word clock card for the RayDAT, therefore do not have word clock at all. Then Daniel's proposal is the only possible setup. Also clocking quality is not the problem here, if at all the ADCs used in those converters...
