DAT tapes thru SPDIF coax

Trying to play DAT tape thru SPDIF coax connection into Cubase LE mastering. Interface is e-mu 0404. Is this possible? I don’t seem to get any signal in. Device manager recognizes E-Mu but states that its inactive.

Yes it’s possible.
If Windows device manger: It is not relevant for Cubase.
If Cubase device manager: check the manual on how to set up the busses.
