2 UR824's ADAT WCLK setup for slave unit

I noticed that the ‘ADAT A’ light is blinking on my ADAT slave UR824. Does that mean I have the clock setup incorrectly?

I also have a Behringer ADA8000 connected to ADAT B. All are connected via Optical cables as well as BNC.

All seems to work as it should, but that blinking light is sure annoying. :slight_smile:

Any thoughts?

Thanks in advance.
