selection of this chart MUST be defined in the DHS.
The DHS allows to:
• Select the clock the card uses
• Select the input source
• Set analog and digital gains of an input
• Enable Sample Rate Converters of an input
• Select the input monitored on an output
• Set the monitoring gains
• Set the analog and digital gains of an output
• Define the digital output format
