Configuring format parameters
Each standard and custom format is defined by a set of parameters. These parameters
are categorized in the generator as either Options or Settings. You can view and modify
the parameters of a format in the following ways:
• On the generator’s front panel display
• On a display connected to the generator (view only)
• Through the command line interface
• In the format’s XML file
• Through the Format Editor
Viewing and modifying format parameters through the front panel
Procedures for viewing and modifying the format parameters and format options through
the front panel are provided below. Format options are selections that are of a binary
nature, i.e. either on or off. Settings are attributes of a format that can take on a wider
range of values.
Note that format setting and option changes made through the front panel do not persist
through power cycles or changes in formats. If you make a change to a format parameter,
then choose another format, and then go back to the format you changed, you will find that
the parameter has been reset to the default value for that format.
To view and modify a format’s options using the front panel:
1. Press the Source key and choose a format by pressing the adjacent soft key.
2. Press the Options key. The format options appear on the generator’s display as shown
below.
3. To set an option, do one of the following:
a. To choose an option, press the soft key adjacent to the option. An asterisk (*)
appears next to the option, indicating it is selected.
b. To enable or disable an option, press the soft key adjacent to the option. A + sign
indicates the option is enabled; a - sign indicates it is disabled.
c. To set an option to a value (for example, AFD), increment the value by pressing the
+ key.
