Step 3: Selecting a Service
The TDR60 automatically selects the first service in the transport stream. You
may need to select another service. To select a service using the front panel:
1. From the main menu select Service>Available Services. The LCD displays
the current service.
2. Select the service, which begins to flash.
3. Scroll through the list of services until the required service is displayed.
4. Press the Enter button.
To select a service using the remote unit issue the command
DC PROG #,
where
#
is the number of the required service.

TDR60 Detailed Configuration Procedure
To configure the TDR60 to your site-specific requirements, follow the
Configuration Procedure found at the beginning of this chapter.
Example
All examples presented in this section follow the TDR60 Configuration Procedure
presented at the beginning of this chapter and use the DVB factory configuration
as the default.
In the TDR60, both the video decoder and the audio decoder are fully auto-detecting, which means
that the TDR60 automatically sets all of the video and audio parameters required for operation based
on the incoming service signal. Since the TDR60 audio and video decoders are auto-detecting, the
only TDR60 parameters you must configure to establish communications are those required for the
demodulator and service selection.
This example configures the TDR60 to a basic SCPC setup. Use this example as a
guideline, substituting your site-specific parameter values as required.
Step 1:
In this example, assume that the following is a list of your TDR60
operational parameters:
■
RF Freq: 11.774 GHz
■
LO Freq: 10.750 GHz
■
Data Rate: 8.448 Mbps
■
Code Rate: 3/4
■
LNB Power: 13V
Step 2:
After comparing these operational requirements against the TDR60 DVB
parameters, it is determined that the following parameters need to be set:
■
RF Freq: 11.774 GHz
■
LO Freq: 10.750 GHz
■
Code Rate: 3/4
■
LNB Power: 13V
Since the TDR60 audio and video decoders are auto-detecting, the audio and
video parameters do not need to be set.
