Configuring the TDR7

Configuring the

TDR7 to DVB Defaults

Your

TDR7 is configured to DVB default parameters before it is shipped

to you to allow you to quickly establish communications. Once the
configuration parameters have been changed from the DVB defaults,
you can easily restore them.

To restore the TDR7 to DVB default parameters:

At the RCD prompt, type

MC_FLASH_DVB

, then press the

Enter

key.

Keep in mind that when you restore the

TDR7 parameters to DVB

defaults, the demodulator parameters also revert to the DVB defaults.
Unless your incoming signal frequency and polarization, LO frequency,
Viterbi code rate, and transport stream data rate parameters all match
the DVB default settings, you will not be able to achieve demodulator,
decoder, or transport stream lock.

After you have restored the

TDR7 to the DVB defaults, you can

configure the demodulator to the parameters you require, then issue
the

MC_FLASH_SAVE

command. Then, whenever the

TDR7 is

powered on or reset, the unit restores the demodulator to the
parameters you specified, and restores all other parameters to the DVB
defaults.
