Set the Data Options
Navigate to the
Data
Menu
. If serial data, either RS-232 or RS-422, is to
be encoded then configure the input source and bit-rates.
4.9
Set the Output Options
The
Output Menu
allows the output of the Encoder to be selected. If the
modulator output is to be used then the Output Format should be set to
Sat. Modulator.
The
Satellite Modulator Menu
is then available to allow all the
modulator parameters to be configured.

Configuring Option Cards
For information regarding configuring any option cards that may be
fitted to the Encoder refer to the Reference Guide.

Satellite Modulator Control
A major advantage of having the satellite modulator integrated into the
Encoder is that the Encoder bit-rate can be automatically linked to the
satellite modulator modulation type, symbol rate and FEC rate.
Changing any one of these parameters causes the others to be
automatically updated.
4.11.1
Initial State of the Modulator
Following power-up the Modulator is configured into a safe state such
that:
>
The Modulator output is off.
>
Modulation is switched on.
>
The output power is set to the ‘Low’ setting.
The exception to this is if ‘Power Dip Recovery’ (in the
Setup/General
Menu
) has been enabled, and the power interruption was less than
eight seconds. In this case the unit will power up in the same state as
when the power failed.
