The Serial number will "attach" the cablecard to your account so it can access the programming you subscribe to.RavenFan said:Are these numbers required to activate the card? I supplied a HostID and Card ID that appeared in the Pairing display on the TiVo. A CSR asked for the cable card model, but I didn't know it. I'll try to call with this info tomorrow.
Of course, the tech that came to my house had never seen a cableCARD and only supplied the Serial Number when he called his dispatcher.
The HostID/CardID will marry the card to your set.
