Installation

This section provides instructions to cable the DCT3080 and check its
operation. The cabling diagrams illustrate connections to high-definition
or standard-definition TVs, home theater receivers, and stereo VCRs.

Important Safety Considerations

The DCT3080 requires careful handling to avoid potential damage to its
internal hard disk drive or the loss of recorded data. Be sure to follow these
requirements during transportation and installation.

During Transportation to the Subscriber Home

Transport the cable terminal in its shipping box or an equally padded
container.
Do not expose the terminal to rain or moisture.

During Installation

• Do not place the cable terminal in an enclosed area where the

cooling vents are blocked or impede the flow of air through the

ventilation openings.

• Install the terminal so that its position does not interfere with its

proper ventilation. For example, do not place the terminal on a

bed, sofa, rug, or similar surface that could block the ventilation

openings.

• Install the terminal away from heat sources such as radiators,

heat registers, and stoves. Installation of the terminal near

17

DCT3080 Installation Manual

consumer electronics devices, such as stereo receiver/amplifiers

and televisions, is permitted as long as the air surrounding the

terminal does not exceed 40 ºC (104 ºF).

• Place the terminal on a flat surface not prone to vibration or

impact.

• Do not install the terminal in an area where condensation

occurs.

• To prevent the temporary loss of guide data and cause a

temporarily non-responding terminal, do not plug the AC power

cord into a switched power outlet.

• To avoid shock and vibration damage to the internal hard drive,

do not move the terminal while it is plugged in.

• To allow the hard drive to spin down and park its heads, wait at

least 10 seconds after disconnecting power before moving the

terminal.

Before You Begin

Before you move or change components on the subscriber
entertainment system:

 Review the installation instructions.

 Determine if you are connecting to a standard TV, a composite

(baseband) monitor, or a component monitor.

 Verify that you have the necessary cables and other required items.

Note: If the terminal was previously used, clear its hard drive before
installing it at a new subscriber location.

Clearing the Hard Drive

On a previously used cable terminal, delete all recorded programs from
the hard drive before installing it at a new subscriber location. This
prevents your new subscriber from viewing programming they may not
have purchased or may not want to see.

To prevent subscribers from accidentally deleting all of their recorded
programs, a specific set of keystrokes is required to clear the hard drive.
Having a TV connected is optional.
To clear the hard drive:

off, and complete the clearing process.

Video Connection Options

Use the following guidelines to determine the best video connection for
the subscriber home entertainment system. To determine the available
video inputs on the TV, check the manual supplied with the TV or the TV
itself.

The DCT3080 offers the following video outputs:

S-Video

Video
(composite)

SDTV

only

SDTV

only

If your TV has an S-Video input, use S-Video. S-Video is
the highest quality standard-definition video output on
the DCT3080.

If your TV does not have an S-Video input, use the
composite video (

VIDEO) output.

RF

SDTV

only

If your TV only has a coaxial RF input, connect it to the

DCT3080

RF OUT connector.

19

DCT3080 Installation Manual

Audio Connection Options

Connect the stereo audio cable to the AUDIO R and L connectors on the
DCT3080 and the audio left and right connectors on the TV. If the
equipment supports it, use the
output instead of the

AUDIO R and L outputs. In most cases, these

outputs offer better audio quality, including support for 5.1 Surround
Sound.
When connecting to a home theater receiver, depending on its inputs,
you can use the following DCT3080 audio outputs:

OPTICAL SPDIF OR
COAXIAL SPDIF

BASEBAND
AUDIO

R AND L

If the receiver supports it, use the

SPDIF audio output to deliver Dolby AC-3 audio to a Dolby

Digital home theater receiver.

If the audio receiver does not support Dolby Digital, use the
baseband
receiver.

The cabling diagrams show sample audio/video (A/V) connections to an
audio receiver, where the receiver functions as an A/V router. When
connecting to an audio receiver, reference its installation instructions for
directions on connecting to baseband and SPDIF ports.

The VCR and TV receive their A/V signals from the currently selected
input device on the audio receiver. This is important when the subscriber
has another A/V device such as a DVD player, a secondary VCR, a CD
player, or other electronic component. We recommend connecting the
TV to the monitor output so on-screen menus for the receiver can be
displayed. (In many cases, the receivers themselves have interactive
on-screen menus.)

Installation Overview

You are connecting to a standard definition TV – Connect the S-VIDEO
connector using an S-video cable, or connect the composite
connector using an RCA phono cable. If the TV only has a coaxial RF
input, connect it to the DCT3080

RF OUT connector.

Determine if you are connecting the audio to a home theater receiver or
directly to the TV:
 If the receiver or TV has an SPDIF input, use the optical spdif or

coaxial spdif outputs.

 Otherwise, use the baseband left and right audio out outputs.

1 Locate the cabling diagram(s) that best match the subscriber

configuration.
