(If you are trying to connect a Digital Transport Adapter (DTA) to your Series2 DVR, click here.)

A tuning adapter is a small set top box that gives your CableCARD-equipped TiVo box the ability to request switched digital video (SDV) channels. Like CableCARDs, tuning adapters are part of the digital cable system, so they must be issued by your cable provider.


Tuning adapters are installed in the cable line between your TiVo DVR and your cable wall outlet. An additional USB connection is used by the TiVo DVR to send channel tuning requests to the tuning adapter, which transmits the requests back to the cable system.


Tuning Adapter Installation 

Installation Instructions 

1. Install your CableCARD(s) and confirm they are activated by ensuring you can view all the non-SDV channels in your cable package.

CableCARDs are required for decrypting programming and for decoding copy protection on your channels. CableCARD(s) must be working properly before you can test the operation of a tuning adapter.

2. Remove the coaxial cable from the TiVo device.

3. Attach the coax cable from the wall to a coax splitter.

4. From the coax splitter, connect one coax cable to the tuning adapter, and one to the TiVo device.

5. Connect the USB cable from the tuning adapter to the TiVo device.

Note:  TiVo EDGE and TiVo BOLT users: always connect the USB cable to the TOP USB port.

6. Plug in the tuning adapter power cable.

The tuning adapter will start up and download a channel map, which contains information the TiVo device requires to tune to your channels. While the channel map is loading, you will see "Please wait. Acquiring Channel Information" in Live TV.

Your cable provider may require you to call to activate your Tuning Adapter before the adapter can download the channel map. If you still see "Please wait. Acquiring channel information." after 20 minutes, contact your cable provider.



  • Make sure the Tuning adapter is hooked correctly. 
  • Tuning adapter light must be solid. If blinking, then reboot. 
  • If the issue persists, refer to your carrier. 

7. Once the channel map is loaded, test your channels.

If you are using a MoCA network and a TiVo Bridge with your setup, you will need an additional split in the coax line. See MoCA Networking: Help for a diagram of this setup.
