3 INSTALLATION
Before You Begin
Before you move or change components on the subscriber’s entertainment system:
•
Review the installation instructions.
•
Determine if you are connecting to a standard analog NTSC TV (supporting an RF
input), a composite (baseband) video input, or an S-Video input) or a High-Definition
TV (supporting component video input, HDMI input, or an IEEE-1394 input).
•
Determine if the subscriber has other equipment to be connected to the terminal
(home theater or A/V receiver, VCR, etc.)
•
Verify that you have the necessary cables and other required items.
•
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 the Diagnostics section; d 01 is displayed on the
front-panel display.
2. Using a remote control, within five seconds, press REPLAY, MY DVR three times, and
LIVE TV. (On some remote controls, the MY DVR key may be labeled LIST.)
3. If you correctly enter this key sequence in five seconds or less, the hard drive is
cleared and the front-panel displays Clr.
4. If Clr is not displayed, re-enter the key sequence in step 2.
5. If Clr is displayed, press any other key to reset the terminal, turn it off, and complete
the clearing process.

3 INSTALLATION
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 DCH3416 offers the following video outputs:
Component
(YPbPr)
HDTV and
SDTV
The YPbPr 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-DVI converter cable or adapter to connect to the DCH3416 HDMI
connector.
If you use IEEE-1394, on-screen graphics do not display.
S-Video
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 DCH3416.
Video
(composite)
SDTV only
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 DCH3416 RF out
connector.
Audio Connection Options
When connecting to a home theater receiver, depending on its inputs, you can use the
following DCH3416 audio outputs:
Digital audio optical
(S/PDIF) or digital audio
coaxial (S/PDIF)
Baseband Audio L and R
If the receiver supports it, use the digital audio optical (S/PDIF) or digital
audio coaxial (S/PDIF) audio output to deliver Dolby AC-3 audio to a Dolby
Digital home theater receiver.
•
For an HDMI or IEEE-1394 video connection, no additional audio
connections to the TV are required.
•
For RF output, no further audio connection is required.
If the audio receiver does not support Dolby Digital, use the baseband
AUDIO L and R outputs to connect to the audio receiver.
Connect the stereo audio cable to the AUDIO L and R connectors on the DCH3416 and
the audio left and right connectors on the TV. If the equipment supports it, use the
optical SPDIF or coaxial digital SPDIF output instead of the AUDIO L and R outputs. In
most cases, these outputs offer better audio quality, including support for 5.1 Surround
Sound.
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 digital
audio (S/PDIF) ports.
10
3 INSTALLATION
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
1. Determine if you are connecting to a:
High-Definition
TV or monitor
Use the component video (YPbPr), HDMI, or IEEE-1394 outputs. No other video
connection supports HDTV.
If your TV has a DVI input, connect a DVI-to-HDMI adapter or cable to the HDMI out
connector on the DCH receiver instead of the IEEE-1394 connection and the DVIHDTV connector on your TV.
StandardDefinition TV
Connect the S-Video connector using an S-video cable or connect the composite
video connector using a composite (RCA phono) cable. If the TV only has a coaxial
RF input, connect it to the DCH3416 RF OUT connector.
2. Determine if you are connecting the audio to a home theater receiver or directly to
the TV:
•
For an HDMI or IEEE-1394 video connection, no additional audio connections to
the TV are required.
•
If the receiver or TV has a digital audio (S/PDIF) input, use the digital audio
OPTICAL (S/PDIF) or COAXIAL (S/PDIF) outputs.
•
Otherwise, use the baseband left and right audio out outputs.
3. Locate the cabling diagram(s) that best match the subscriber’s configuration.
4. Connect the audio and video cables in a manner matching that diagram.
5. Determine if you are connecting to a data device (see Data Device Connections in
this section). For installation details, refer to the instructions included with the data
device.
6. Connect the cable terminal to the coaxial cable wall outlet.
7. Perform the operational check for the remote control.
8. Optimize the High-Definition settings. See Optimizing the High-Definition Settings in
this section.
11
3 INSTALLATION
Cabling to an HDTV for Video
For the best possible HDTV video quality:
•
If the TV has an HDMI input, connect it to the DCH3416 HDMI output. If the TV has a
DVI input, you can connect it to the DCH3416 HDMI output using and HDMI-to-DVI
converter cable or adapter.
•
If the TV has neither an HDMI nor a DVI input but has an IEEE-1394 input, connect it
to the DCH3416 IEEE-1394 output. If you use IEEE-1394, on-screen graphics do not
display.
•
Otherwise, use the component video (Y, Pb, and Pr) connectors.
Note: Be sure to match up each signal to the same connection on the TV. Otherwise,
the colors will not appear correctly on your TV.
Figure 3-1 Cabling to an HDTV
Because HDMI and IEEE-1394
provide both video and audio
output, no additional audio
connections to the TV are required
if you use either of these
connections.

If the receiver can check the baseband and digital audio (S/PDIF) ports for appropriate
channels, connect both the baseband and digital audio connections. Otherwise, do not
connect both the baseband left/right composite connections and the coaxial digital
connection. The baseband connections are not necessary because the digital audio port
provides a single audio interface for digital channels.
Note: If the A/V receiver includes HDMI inputs & output(s) then the DCH3416 HDMI
output can be directly connected to the A/V receiver.

MAC Abort
Cntr
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 DCH3416
receives an ACK. If the counter reaches the MAC abort count limit, the DCH3416
assumes the MAC layer is unavailable due to noise, congestion, or some other problem.
The DCH3416 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
the default or if the MAC Abort CNTR is not configured or unknown.

Problem
Possible Solution
The DCH receiver will
not power on
The DCH receiver may have received a software update and may not power on while the
new software is being installed. Try again in a few minutes.
The remote control
does not work
•
Verify that the AC power cord is connected to the DCH receiver and an AC
outlet. Unplug the DCH receiver from the AC outlet, plug it back in, and then
press the POWER button.
•
If the DCH receiver is connected to a switched outlet on another unit, verify that
that unit is powered on. Unplug the power cord from the DCH receiver’s AC
outlet, plug it back it in, and then press the POWER button. It is recommended
to use an unswitched outlet, if possible.
•
Press the POWER button on the DCH receiver’s 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 DCH
receiver. Aim the remote control directly at the DCH receiver front panel, not the
TV or VCR.
The angle between the remote control and the DCH receiver may be too large. Stand in
front of the DCH receiver 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 DCH receiver front panel.
•
Check the batteries in the remote control. Install new batteries if needed.
•
Verify that the mute button on the DCH receiver or the remote control has not
been pressed. Press MUTE on the remote control to restore sound.
•
If the DCH receiver audio output is connected to the TV, verify that the mute
button on the TV has not been pressed.
•
If the DCH receiver 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 has not been pressed.
•
Verify that you have the correct cables for the audio connections.
•
Verify that the audio cables are firmly connected between the DCH receiver 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 S/PDIF cable (coaxial or optical) is firmly connected to the DCH
receiver 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®, Dolby Pro Logic®).
•
Verify that the receiver is properly configured to work with all connected
speakers.
•
Verify that the TV is powered on and set to the appropriate input source for the
DCH receiver.
•
Verify that the DCH receiver is powered on and tuned to an authorized cable
channel.

5 TROUBLESHOOTING
Problem
Possible Solution
•
Verify that all video cables between the DCH receiver and the TV are firmly
connected.
•
Verify that the coaxial cable feed is firmly connected to the DCH receiver and the
wall jack.
•
If the DCH receiver video output 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 DCH receiver video output is connected to a TV through an HDMI
connection, power off the TV and then power off the DCH receiver. 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 DCH receiver. To select a different format:
No graphics or
program guides
appear on the TV
screen
No closed captions
display
•
Ensure that your DCH receiver is plugged into a power outlet and is turned off.
•
Press the MENU key on the front panel. Your settings are displayed on the DCH
receiver front panel display.
•
Press the ▲ and ▼ keys to display the HDMI/YPbPr OUTPUT setting.
•
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 by the DCH receiver. On-screen graphics and captions
may still be overlaid by your TV, if enabled. Alternatively, use HDMI or component video
instead.
•
Verify on the User Settings menu that closed captions are enabled on the DCH
receiver.
•
Verify that closed captions are enabled on the TV.
Note: Closed captioning may not be available on the current program.
There are black bars
to the right and left of
the picture
Widescreen 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 widescreen TVs to
stretch the video to fill the screen (see your TV manual for information about stretching
4:3 video).
•
If the DCH3416 is connected to a widescreen 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.
There are black bars
above and below the
picture
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 DCH3416 is
tuned to a 4:3 program.
•
Set the TV TYPE to 4:3 Pan-Scan. This enables the DCH3416 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 widescreen 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).
60
5 TROUBLESHOOTING
Problem
Possible Solution
There are black bars
on all four sides of the
picture
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 widescreen 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 DCH3416 cannot correct the video. You
may be able to minimize the border using the zoom feature on the TV.
Colors do not appear
correctly
Be sure to match up each signal to the same YPbPr connection on the TV. Otherwise,
colors will not appear correctly on your TV.
The DCH receiver is
making a humming
noise.
The DCH3416 includes an integrated hard drive and a fan for cooling. During normal
operation, the DCH3416 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 DCH receiver. Please note the hard drive will stay on even
when the DCH3416 is turned off (standby).
