System Parameters
MDCP protocol version 3.0 adds commands for setting and querying configuration and other system
parameters. These commands greatly simplify the MDCP command set and supersede several configuration
commands.
System parameter values can be set in Stored memory and/or Active memory. Stored values are loaded on
system startup. Active values are the current control values of the running system, but wont be retained after a
system restart if they differ from the Stored value.
