I've got a couple new IF-AD/DM (ADAT) cards and am finding that my DM-24 is not playing well with them. Upon selecting inputs from the cards, I will get either no input or full level digital noise. I have no issue with input from my Presonus Digimax using the built-in ADAT connector, but when using the ADAT cards in the option slots, no dice. My machine is at V2.10. Tascam says that first thing to do is to update the mixer to V3.0. Has anyone else had bad luck with IF-AD/DM cards and V2.10? Any suggestions in getting the cards up and running properly in my V2.10 mixer? I don't mind doing the update, but, if not necessary, I'd rather skip it, unless there are other benefits.
