Thanks all for everything. I didn't see anything in the bios that mentioned any ports, and I went through all the menus, twice. I will check again. I'll look into the null modem cable thing. I gotta pull the package out the trash!

And yeah joykrash, I am on SP2 as well. Trying to work this all in with Pro Tools. The only reason I need this interface is because I just got a second MPC and want my Mbox to sync to both of them when I need, as well as use both MPC's to sequence my hardware and soft synths, all without having to move cables around. Everything was so simple with 1 MPC.
The one thing I am really confused on is where exactly am I supposed to go to even select a port for the unit to connect to? The manual says to do so right in this following menu, but there is no where to select it??? And how is the unit detect? To my understanding, it's not like USB where you plug it in and it just pops up. I tried turning the power on and off and nothing ever happens.
