DCT3412 Installation Manual

Section 3

Installation

This section provides instructions to cable the DCT3412 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 DCT3412 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 consumer electronics devices, such as stereo receiver/amplifiers and televisions, is permitted as long as the air surrounding the terminal does not exceed 40º C (104º F).

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.

DCT3412 Installation Manual

3-2 Installation

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:

1 Start the Diagnostics as described in Section 4, “Diagnostics.”

The DCT3412 offers the following video outputs:

Component (Y Pb Pr)

HDTV and

SDTV

The Y Pb Pr outputs provide component video, the most widely supported HD video connection.

HDMI or IEEE 1394

HDTV and

SDTV

HDMI and IEEE 1394 offer higher quality HD video than component video. If the TV has an HDMI or a DVI input, use the

HDMI output instead of the IEEE 1394 output.

HDMI and IEEE 1394 are video and audio connections. If you use HDMI or IEEE 1394, no separate audio connection to the TV is required.

HDMI is compatible with DVI. If the TV has a DVI input, you can use an HDMI-to-

HDMI connector.

S-Video

DVI converter cable to connect to the DCT3412

If you use IEEE

1394, on-screen graphics do not display.

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 DCT3412.

Video

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

VIDEO) output.

(composite)

SDTV only If your TV only has a coaxial RF input, connect it to the DCT3412

RF OUT connector.

Audio Connection Options

Connect the stereo audio cable to the AUDIO R and L connectors on the DCT3412 and the audio left and right connectors on the TV. If the equipment supports it, use the coaxial digital

SPDIF 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

DCT3412 audio outputs:

OPTICAL SPDIF OR

COAXIAL SPDIF

BASEBAND

R AND L

AUDIO

If the receiver supports it, use the Dolby AC-3 audio to a Dolby Digital home theater receiver.

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

OPTICAL SPDIF or coaxial SPDIF audio output to deliver

OPTICAL SPDIF or

AUDIO R and L

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.)

Installing the Optional IR Blaster

The optional IR Blaster provides control of the subscriber VCR from the terminal. It consists of a low-power infrared transmitter attached to a six-foot cord and a mounting bracket. The mounting bracket is a clear plastic holder that has a pad of adhesive tape that enables you to install the IR Blaster near the VCR IR receiver. A mini-pin connector at the end of the cord connects the IR Blaster to the terminal. The IR Blaster is sold separately as an accessory item.

The availability and functionality of the IR Blaster depends on the installed application software. Some IPGs may not support the IR Blaster.

Figure 3-7 IR transmitter installed in mounting bracket

Once installed, the IR Blaster is activated automatically through the electronic program guide. Individual VCR codes are broadcast through the out-of-band data channel and are updated periodically as new codes are added.

The procedure for installing the IR Blaster is described in the following paragraphs.

Locating the IR Receiver on the VCR

The IR receiver area is not visible on some VCRs. To locate it:

 Obtain a piece of opaque material, such as a 3- by 5-inch index card.  Use the card to block off areas of the VCR where the IR receiver might be located. Try to

turn the VCR on and off with the remote control pointed directly at it, and close enough to reduce the possibility that the receiver will see IR reflections.

 Note the blocked area where the VCR is unresponsive to the remote control. This region

contains the sensor and can be marked by loosely taping the index card to the area.

Because the IR Blaster radiates in an area approximately 40 degrees wide, you do not need to be precisely on target with the receiver. You may prefer to offset the location of the IR Blaster transmitter so that it is less likely to interfere with operation of the VCR remote control.

DCT3412 Installation Manual

3-16 Installation

Connecting the IR Blaster

To connect the IR Blaster:

1 Fit the transmitter into the mounting bracket (refer to Figure 3-7). 2 Plug the mini-pin connector into the

Figure 3-8 IR Blaster installed

IR jack on the rear panel:

3 Remove the adhesive tape cover from the mounting bracket. 4 Position and press firmly to attach the mounting bracket to the IR receiver on the VCR. Be

careful to route the wire so that it does not prevent loading tapes.

Checking the IR Blaster

The IR Blaster is now located near the receiver and the VCR can be controlled through the terminal. As a final check, operate the VCR using the remote control from various positions in the room. If the IR Blaster is obstructing the IR receiver on the VCR, move it slightly.

Boot Cycle

After connecting the proper cabling to the DCT3412, plug the power cord into the DCT3412 and electrical wall outlet. Begin performing the boot cycle procedure:

 After a few moments, the LED displays HUNT and then FR 1.  The DCT3412 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 DCT3412 model is acquired.

 The LED displays and OOB frequencies are:

 When the correct OOB frequency is acquired, the LED flashes FR number.  When multiple OOB frequencies are used, the DCT3412 pauses 40 seconds on each valid

frequency. The LED displays dl and a progress indicator, which identifies a software object download. The progress indicator, or crawling ant, moves one position around the dl display for each segment of download received. If the dl stops moving up and down on the LED for an extended period of time, contact the headend operator.

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

 When the LED display is blank, the terminal is ready for initialization and service

authorization using the addressable controller. Verify that the terminal is powered up or reset within two minutes of a completed download.

Field Description

MAC Abort Cntr

Socket Port State

This counter increments every time the MAC layer reaches the cell abort count limit. It is reset by the successful upstream transmission of a cell – for example, when the DCT3412 receives an ACK. If the counter reaches the MAC abort count limit, the DCT3412 assumes the MAC layer is unavailable due to noise, congestion, or some other problem. The DCT3412 stops transmitting data upstream, reports an error to the calling function, and attempts to re-enter the network using the initialization process. 0000 is displayed as default or if the MAC Abort CNTR is not configured or unknown.

The socket mode and activity:

 UNUSED — The socket is not being used.  OPENED — The socket is open.  READY — The socket is ready to send or receive.  RECEIVING — The socket is receiving data from the application server.  SENDING — The socket is sending data to the application server.  UNKNOWN — The socket state is invalid or unknown.

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

There is no audio when viewing cable channels

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

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

POWER button.

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.

Verify that the

MUTE on the remote control to restore sound.

Press

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

MUTE button on the cable terminal or the remote control was not pressed.

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

II, or Dolby Pro Logic).

Verify that the receiver is properly configured to work with all connected speakers.

Problem Possible Solutions

There is no video on the TV screen

No graphics or program guides appear on the TV screen

No closed captions display

There are black bars to the right and left of the picture

There are black bars above and below the picture

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.

If the cable terminal is connected to a home theater unit, verify that the home theater unit is powered on and set to the appropriate input source.

If the cable terminal is connected to a TV through its HDMI connection, power off the TV and then power off the cable terminal. Wait one second and then power on the devices.

Not all HDTVs can display every output format (1080i, 720p, 480p, or 480i) available on the cable terminal. To select a different format:

Ensure that your cable terminal is plugged into a power outlet and is turned off. Press the

MENU key on the front panel. Your settings are displayed on the cable

terminal front panel display. Press the ▲ and ▼ keys to display the HDMI/YPbPr OUTPUT setting. 1 Press the • key to cycle through the available output formats until a picture

displays on the TV.

If you use the IEEE 1394 connection, on-screen graphics, including closed captions and program guides, are not displayed. If possible, use HDMI or component video instead.

Verify on the User Settings menu that closed captions are enabled on the cable terminal.

Verify that closed captions are enabled on the TV.

Wide screen TVs display 4:3 programs in this format unless set to Stretch. Turn on the 4:3 OVERRIDE feature in the User Settings menu. This enables most wide screen TVs to stretch the video to fill the screen (see your TV manual for information about stretching 4:3 video).

If the cable terminal is connected to a wide screen TV, verify that the TV TYPE is set to 16:9 in the User Settings menu.

Many HD programs are broadcast in pillar-box format with black bars to the left and right of the picture. These programs are broadcast in 16:9 HD formats, even though the video is not 16:9.

All 4:3 HDTVs display HD programs in letterbox format (black bars above and below the picture) because of the shape of the display screen.

Turn on the 4:3 OVERRIDE feature in the User Settings menu. This enables most standard screen TVs to display a full screen picture when the cable terminal is tuned to a 4:3 program.

Set the TV TYPE to 4:3 Pan-Scan. This enables the cable terminal to remove the black bars above and below the picture when possible.

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. (See your TV manual for information about zooming 4:3 video.)

DCT3412 Installation Manual

Troubleshooting 5-3

Problem Possible Solutions

There are black bars on all four sides of the picture

The cable terminal is making a humming noise.

This may occur on a 4:3 TV if the 4:3 OVERRIDE setting is OFF. To set 4:3 SD programming to fill the screen, depending on the capabilities of the TV, set 4:3 OVERRIDE to 480i or 480p.

This may occur on a 16:9 TV if the active video for an SD broadcast is in letterbox format. To confirm, wait for a commercial or look for a graphic, such as a network logo. If the commercial fills the screen from top to bottom, or the graphic appears below the active video, the program is being letterboxed by the broadcaster. You can minimize this by activating the zoom feature on the TV.

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. You may be able to minimize the border using the zoom feature on the TV.

The DCT3412 includes an integrated hard drive and a fan for cooling. During normal operation, the DCT3412 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 DCT3412. Please note the hard drive will stay on even when the DCT3412 is turned off.
