What exactly IS a Lightning to 30-pin adapter?

Hi everyone, first post here.🙂

So, this week (hopefully), my Product Red, engraved, 5th Gen iPod touch is coming in. Although I didn't order a Lightning to 30-pin adapter, I may get one for Christmas. I have a Sony iPod Docking station (only works with earlier gens). Does the Lightning to 30-pin adapter have 30-pin on bottom and Lightning on top? So, like, it just plops right onto the Dock and then put my iPod 5th gen on top?

Thanks for any help.😉
