I ask this, because TiVo and Spectrum, give two different ways to setup a tuning adapter. Tivo tells you to connect the coaxial from the wall to a splitter, then have two separate coaxial cables from the splitter. One cable going to the tuning adapter in, and one going to the TiVo. With the only direct connection between the two is a USB cable. Tivo Customer Support Community Spectrum's self install pamphlet, tells you to connect the coaxial from the wall directly to the tuning adapter in, then a separate coaxial cable from tuning adapter out to TiVo coaxial. You plug in the tuning adapter and wait until the light turns green, which is supposed to take 10 minutes. (Mine hasn't yet after 30 minutes, and spectrum chat is currently not working). Then you add the USB cable (TOP usb port). I think my tuning adapter needs to be turned on/paired. I'm going to call tomorrow if I need to, so I'm getting a jump on this thread. I wanted to know which way was correct, but I would REALLY like to know WHY? Thank you. (I just noticed I am getting 8 blinks. I searched and found this thread: Tuning Adapter Blinking That says that the TA is not paired. I am going to sleep, I will call later).
