Syncing a DA88 with Cubase 4

I have a DA88 and Cubase 4, SY88 installed. I also have two MTPAVs. Mac computer Presonus Firepod/FP10. I wanted to know how to sync the DA88 with Cubase 4.
I have already just ran the DA88 and connected the audio outs to the Presonus and just did a little editing. But I figured it could be easier somewhat to just sync the two.
Also I wonder if it's possible to just digitally transfer the audio from the DA88 into Cubase?
