Can someone help me hook up my PS2 to my old Orion TV?

I have an old tv - an Orion No. TV1329B - and I want to connect my old game system - PS2 - to it. The tv only has a coaxial connection for an antenna on the back of it. I bought an RCA digital converter box - model DTA800B1 - (and antenna) for it, and it works for showing tv channels - but I can't make it play my PS2. The converter box has the audio/visual ports for the system, but I don't know how to make the screen show the game. Can someone please help me?
