Topic: UFX adat led blinking

Hello,
I have a setup with 3 RME products, 2 UFX+ and one UFX.
I have connected the 3 soundcards with the originaloptical cable present in the box.

I see the LED of the ADAT 1 of the third fireface (the UFX) blinking, differently from the LED of the other two UFX+ that is steady. Is this indicating a synch error? How can I solve it?

Apparently I solved it, I just needed to configure the clock in the settings. Now the led does not blink any longer
