Thanks for posting to our Forums! I'm sorry to hear you are having an issue hooking up your Slingbox 500.
Below is an article that will explain to you what you need to use the Slingbox 500:

I also need a solution to this problem. I have no set top box. Do you have a recommended minimal set top box that can be bought rather than rented from the cable company. I have basic cable at $20 a month and getting a set top box from them will double that cost. Or is there a computer video/tuner card that will work and give an HDMI output that can be the input to the Slingbox. Then I could use WIndows Media Center perhaps.
As I understand the operation, the Slingbox does not have a tuner in it. It can control a tuner, or decoder, or set top box, through the infra-red.
Mine is a Slingbox 500.
Your previous link to the spec sheet was not helpful.
