7.3.15.2 Data Description
sys_param_values:
Data Type: Array of unsigned 8 bit Integers
Max Each value is set by its system parameter definition.
Array Size: Set by the System Parameter Count in the “Unit Configuration Packet”.
7.3.15.3 DC-2/MC-1 Response
The DC-2/MC-1 will assign the values from the packet to the system parameter values in Nonvolatile RAM,
and reset the unit to initialize the new values.
7.3.15.4 Data Validation
If any of the values exceeds it’s maximum value the DC-2/MC-1 will ignore the command and transmit a
DC_NAK command with an error code DC_INVALID_DATA.
7.3.16 Set Effect Parameter Values
Commands DC-2/MC-1 to replace the given effect parameter values with the values in this packet.
