ADI 4 DD not working well with Lynx Aurora 16 Original

In the stripped down version, i'm just using the aes d-sub 25 connector to the aurora 16 from the RME Adi dd, and it doesn't work.....not using the aes xlr at all......One odd thing that happened is if I switch the sync source on the Aurora to AES the blinking stops...but there should be no master clocking coming from the adi 4dd......

Tried another d-sub cable that was previously used successfully in a lynx aurora linked to a tascam wired interface - however, didn't work in my setup. Can not get the adi to sync by word clock unless the dsub cable is disconnected.....The adi will sync to either a burl b2 or the aurora by wc as long as the dsub isn't connected. When the adi aes 25 is connected to the lynx aurora the aes status lights only stop blinking when the aurora is set to being clocked by aes from the adi, but the green sync light on the aurora then doesn't light up at all...there appears to be some issue with the aes d sub on the adi regarding syncing......is this fixable? As long as the dsub cable isn't present things generally appear to function on the ADI......I normally clock the adi from the burl via aes xlr input, and then go into an rme digiface usb from an adat out on the adi without any problems. Thought I could go from the aurora 16 via dsub cable to the adi, then to the digiface usb then into a computer.....but it's not working out, won't sync up properly.....

I believe the standard for aes dsub  25 is 4 stereo in and outs for a total of 8 channels each of in and out...total 16 channels. I am going to be able to test another adi 4 dd in a few days....whether that one works or not will be revealing.....

Yes. Details in the manual page 22.

And, are you sure that wiring of that AES cable is correct? And the cable is not defective? As far as I have found on internet, there are 3 different wirings for Yamaha AES DB-25. One for 8 channels in/8 out, one for 16 channels out and one for 16 channels in...

If you have Yamaha breakout AES cable out, or you can borrow it, you might try use that cable connect to ADI-4 DD´s XLR AES in. That would test, if synchronisation works at all. And rule out most risks of wrong pinouts....

You may reveal what those power supplies specifications are ? The cable itself has no influence.
One of your power supplies no longer works correctly.
The ADI-4 DD has very special power input specifications :

It must be within the limits, these are wide.

This one from Thoman would work:

Between 7 and 38 Volt DC, the market has plenty of cheap power supplies in this range, most of them will work.
6 Watt is low power, most power supply can do this.

Bit the bullet and bought an RME power supply in USA.

Maybe the frequency the power source internally uses matters. It should not matter, but who knows....

The other possibility is, that power source in ADI-4 DD is not in the best condition.... And because of some reason works OK with RME power source...

You could try your second ADI-4 DD whether it works with non-RME power sources.... If it works, the problem is in the troublesome ADI-4 DD, not in external power source.
