No signal via ADAT Optical

[almon]

Unable to get an audio signal in to protools via ADAT Optical.
I connected optical cables and verified connection, setup I/O and hardware to ADAT optical,
set session to 48kHz, selected ADAT input on each track, press play on source and still no signal.

I also attempted to change clock soure to OPTICAL but PT would not allow.

What are you using through the optical cable? I have a motu 8pre and my 003 shows the ADAT connection, the tracks are record enabled, channel assignments are correct, and STILL it doesn't show a signal until... I turn the volume knob on the 8pre. I know, it sounds kind of ridiculous, but I read that turning the volume knob can actually do the trick and so far it's worked flawlessly for me. Not sure if this will help you, but I thought I'd suggest it.

That usually means something isn't connected right.

I am connecting a MOTIF ES8 keyboard.
I have the volume turned up on he motif still no signal.
I have also tried reconnecting with a new optical cable and still have no luck.

This is a guess (since I don't own the Motif) but is the optical output of the Motif two-channel S/PDIF?

If so, you need to select S/PDIF as your clock source and make sure your input assignement matches up. I am not in front of my system right now, but I believe S/PDIF input defaults to channels 17/18.
