It is never installed from the casinos. The casinos use a central server for TITO validation. For home use, we buy a product that enables ticket validation. Unless you told your dealer to install it, you probably don't have it. But if you want to look, in the back of the slot there's a grey box with some connectors on it, the top right one is a 5 pin single row molex connector. This is the connector where the TITO home devices connect to. The photo below shows one of my machines. There are various versions of the TITO device for home use. This is just one example, but they all connect to this part as shown.
