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

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.

SDTV

only

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

DCT3080

RF OUT connector.

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.)

Boot Cycle

After connecting the proper cabling to the DCT3080, plug the power cord into the DCT3080 and electrical wall outlet. Begin performing the boot cycle procedure:

 After a few moments, the LED displays HUNT and then FR 1.

 The DCT3080 searches for the headend out-of-band (OOB)

frequency carrier. If the OOB frequency is not set to 75.25 MHz, the LED flashes FR 1 and then flashes FR 2. This searching process repeats until the correct OOB frequency is found and the required message for the DCT3080 model is acquired.

 The LED displays and OOB frequencies are:

Authenticating code object (displays only after download)

The progress indicator usually moves at a consistent rate as segment downloads are received. If all the segments are retrieved in the first pass, the EF, AU, and FP messages are displayed on the LED. If segments are dropped, the progress indicator appears to stall and then inch forward after the dropped segments are retired. The software download may take up to 45 minutes (or longer if the system is experiencing high demand). As long as the progress indicator is spinning, the download is progressing.

When the progress indicator alternates between rapid and sluggish movement, this may indicate that the stream is spinning too fast for existing plant conditions.

 When the software object download is complete, the LED displays:

For up to 60 seconds during flash erasure

For up to 60 seconds during flash programming

Troubleshooting

This section provides troubleshooting guidelines. If problems still occur after performing the diagnostics, call the TRC for assistance as described in Section 1, “Introduction.”

Problem Possible Solutions

The cable terminal will not power on

The remote control does not work

The cable terminal may have received a software update and may not power on while the new software is being installed. Try again in a few minutes.

Verify that the AC power cord is connected to the cable terminal and an AC outlet. Unplug the cable terminal from the AC outlet, plug it back in, and then press the

If the cable terminal is connected to a switched outlet on another unit, verify that that unit is powered on.

Press the POWER button on the cable terminal front panel instead of the remote control. The batteries in the remote control may be depleted.

Verify that the remote control is in “Cable” mode.

Verify that there are no obstructions between the remote control and the cable terminal. Aim the remote control directly at the cable terminal front panel, not the TV or VCR.

The angle between the remote control and the cable terminal may be too large. Stand in front of the cable terminal and not too far to either side.

Press and release operation keys one at a time, firmly and deliberately.

Try changing channels using the buttons on the cable terminal front panel.

Check the batteries in the remote control. Install new batteries if needed.

There is no audio from the center and/or surround speakers of a home theater receiver connected to the cable terminal

Verify that the MUTE button on the cable terminal or the remote control was not pressed. Press restore sound.

If the cable terminal audio output is connected to the TV, verify that the

MUTE button on the TV was not pressed.

If the cable terminal audio output is connected to a home theater receiver, verify that the receiver is set to the appropriate input source and the mute button on the receiver was not pressed.

Verify that you used the correct audio cables for the ports.

Verify that the audio cables are firmly connected between the cable terminal and the audio playback device (TV, receiver, DVD player, etc.).

Not all Dolby Digital programs feature full 5.1 surround sound. In some cases, the programs may only contain left and right stereo audio.

Verify that the coaxial or optical SPDIF cable is firmly connected to the cable terminal and the home theater receiver.

Verify that the home theater receiver is set to a surround sound audio mode (Dolby Digital, Dolby Pro Logic Dolby Pro Logic).

There are black bars on all four sides of the picture

The cable terminal is making a humming noise.

Verify that the TV is powered on and set to the appropriate input source for the cable terminal.

Verify that the cable terminal is powered on and tuned to an authorized cable channel.

Verify that all video cables between the cable terminal and the TV are firmly connected.

Verify that the coaxial cable feed is firmly connected to the cable terminal and the wall jack.

Verify that closed captions are enabled on the TV.

Some SD programs are broadcast in the letterbox format with black bars above and below the picture. Some widescreens TVs offer a zoom feature that may be able to remove the black bars. Note: If tuned to HD and the TV Type = 4:3 LETTERBOX, black bars will appear above and below the picture. Try setting the TV Type to 4:3 PAN/SCAN to get a full-screen picture with no black bars.

A broadcaster may include black bars on either side of a wide screen broadcast. This is called a “hybrid” aspect ratio and results in a black border surrounding the video on a 4:3 TV. Because this is part of the broadcast, the cable terminal cannot correct the video. Borders can be eliminated by selecting the 4:3 PAN/SCAN option on the TV Type setting.

The DCT3080 includes an integrated hard drive and a fan for cooling. During normal operation, the DCT3080 emits a low humming noise, similar to a personal computer. The noise varies in volume occasionally when the speed of the internal fan adjusts to changes in the temperature around the DCT3080. Please note the hard drive will stay on even when the DCT3080 is turned off.
