Section 3

Installation

This section provides step-by-step instructions for installing and cabling the cable terminal in the subscriber’s location. The cabling diagrams shown in this section include the following configurations, both with and without PPV options (STARFONE and STARVUE II):

Standard wiring

A/B Switch-out

A/B Switch-in

If you are adding a VCR or stereo components to the configuration, see Section 4, Adding a VCR or Stereo Components, for cabling suggestions.

Before You Begin

Before beginning the installation process, do the following:

Look at the TV set or monitor to determine if it is a standard TV or a composite (baseband) monitor. Make certain you have the correct connecting cables.

Make certain you have the correct connecting cables for the audio connectors.

Determine if you are going to connect a VCR to the DCT 1000 cable terminal.

If the subscriber location requires an A/B switch-in, an A/B switch-out, or a STARVUE II or STARFONE module, install these options before beginning cabling. Installation of these units is described in the installation instructions provided with them.

After installation is completed, the cable terminal should be placed on a smooth, flat surface with no obstructions to interfere with the free flow of air over, under, and around the cable terminal. Tell the subscriber that nothing should be placed on top of the unit.

Installing the DCT 1000

To install the DCT 1000 in your subscriber’s site: Refer to the section that describes the cabling for the subscriber’s cable terminal configuration:

standard wiring (page 3-2), A/B switch-out (page 3-4); or A/B switch-in (page 3-6).

1 Follow the general instructions as you do the cabling. 2 Perform the basic operational check beginning on page 3-8 after you successfully install

the cable terminal.

3 Check the troubleshooting suggestions on page 3-9 if you have a problem with the

operational check.

DCT1000 Installation Manual

3-2 Installation

General Configuration Instructions

The DCT 1000 cable terminal is available in numerous configurations. The cabling for each configuration is illustrated in this section. Use these general installation instructions and the cabling illustrations to install the terminal in the subscriber location.

To install the DCT 1000 cable terminal: Connect the 75-Ohm coaxial cable drop to the F-type connector that is labeled

RF IN on the

cable terminal.

1 If your configuration includes a STARVUE II module, connect the 75-Ohm coaxial cable

jumper as shown on the appropriate configuration illustration.

2 To connect the video, do one of the following:

For a conventional TV set, use a 75-Ohm coaxial cable with F-type connectors to connect the cable terminal labeled

TO TV either directly to the input of the TV set or through a

matching transformer to the 300-Ohm input of the set. For a monitor, use a cable with an RCA connector to connect the cable terminal labeled

VIDEO to the monitor.

3 Plug the TV set into the convenience outlet on the back of the cable terminal.

Standard Wiring Cabling Diagrams

Figure 3-1 illustrates a standard wiring configuration. If the cable terminal has an RF or telephone return modem, use Figure 3-2 or Figure 3-3) to determine the correct wiring for the configuration.

Figure 3-7 A/B switch-in without a PPV module

If the cable terminal is equipped with a PPV module, refer to the PPV diagrams (Figure 3-8, Figure 3-9, and Figure 3-10) to determine the correct wiring for the configuration. The path for the return system determines which configuration to choose, the one shown in Figure 3-8 (return on cable A) or the one shown in Figure 3-9 (return on cable B).

Operational Check

The operational check tests the communication link between the remote control and the cable terminal. The procedures verify the terminal’s response to the remote control commands. You use the remote control to test a basic cable terminal. If the terminal does not operate properly, refer to the Troubleshooting section.

Testing Procedure Action

Power on 1 Press and release the POWER key to turn on the terminal.

2 Turn on the TV and tune it to the output channel of the cable terminal (channel

3 or 4).

Channel Selection

Volume Control

1 Scan through the channels using the CHANNEL keys on the cable terminal and

CHAN keys on the remote control.

the

2 Tune to several channels by entering the channel number with the numeric

keys on the remote control.

3 Using the TV set volume control, adjust the sound volume to a moderate level. 4 Using the VOL key on the remote control, increase the volume to its upper limit. 5 Again using the VOL key, reduce the volume to its lowest level. Adjust the

volume to a comfortable level using the

6 Press MUTE to turn the sound completely off. Press MUTE again to restore the

sound.

VOL key.

DCT1000 Installation Manual

Installation 3-9

Troubleshooting

Occasionally a terminal may fail to operate as described. Follow these suggestions to correct problems:

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

Aim the remote control directly at the cable terminal, not the TV or VCR. Be sure there are no obstructions between the remote control and the cable terminal.

Be certain that the TV set is tuned to the output channel of the terminal (channel 3 or 4).

If the channels can be changed with the cable terminal buttons, but not with the remote control keys, the problem may be a weak remote control battery or the terminal is not initialized correctly.

In the primary configuration (shown in solid lines), mode A tunes the TV to the VCR output channel and the VCR can record a scrambled or non-scrambled channel. Mode B allows B cable channels to operate in the same manner.

The alternate configuration (indicated by dotted lines), shows an optional placement for a VCR in either the A or the B side.

TV Guide On Screen

The DCT 1000 supports the TV Guide On Screen electronic program guide. If your cable company offers this service, this section will help you get TV Guide On Screen up and running for your subscriber. It also describes a few basic operations to help you introduce the subscriber to TV Guide On Screen. Refer the subscriber to the TV Guide On Screen Reference Guide for complete instructions on all the features and their use.

Remote Control

When operating through the TV Guide On Screen program guide, the DCT 1000 uses the XRC 200 remote control. The XRC 200 may require programming before use; refer to its user guide for programming instructions.
