d8b Forum

Okay, I think I have everything setup correctly and the MOTU 2408 is showing the ADAT light pipe output signal but I can not seem to get that digital signal to show up in the board. Is there any other set up to receive a digital signal on the board. Does the tape in need to be selected? Can't seem to figure this out.
Thanks,
Paul

When you have everything fired up, do you see an alternating flashing * and ? happening in the vaccum display on the console?

I am not sure what a vacuum display is. The card in the back of the d8b that I am plugging into has an input for TDIF and adat and sync. Is this the correct card or do I need a card that just has optical/Adat. I could always try just the TDIF in this card but I don't have one of those cables yet. Any wisdom on this subject would be greatly appreciated.
Thank you,
Paul

I am talking about the window in the meter bridge on the right side just under the Mackie logo. I am trying to determine if your console is seeing clock signal. If it is not, you aren't going to hear audio. You should be able to pick up the embedded signal on the optical/light pipe signal.

Edit: Just found this, also posted on your other thread....

I just found this on the Mackie site. This could be your issue.

Can the DIO-8 card derive word clock from the light pipe input?
No. Like the OPT-8 card, the DIO-8 cannot derive word clock from the light pipe input.


I thought at some point a long time ago I got this to work but I am guessing my memory is wrong on this one.

You can find more info. here:

Can you take the light pipe output from the d8b into an input on the MOTU 2408 and then make it sync to the d8b clock? It looks like that should work.
