Just hook both to your network. If you don't have a network then you can use a crossover cable and assign both a static IP and that should work. The actual process of scheduling all the shows to transfer is a huge PITA. Lots, and lots, of button presses. Plus the S3 units are really slow to transfer so it's going to take a couple days for everything to finish. But once it's done, it's done, and you don't have to worry about it again for at least a few years.
