Software Major Revision: An unsigned 8 bit integer value indicating the unit’s major software version.
The host should use this information to determine if new effects, effect
parameters, or system parameters have been added or removed.
Software Minor Revision: An unsigned 8 bit integer value indicating this units minor software version.

specification.
Protocol Minor Revision: An unsigned 8 bit integer value indicating the serial communication protocol
minor version. The host should use this value to determine if the existing
commands, notifications, or response packets have changed in this specification
Parameter Count: An unsigned 16 bit integer value indicating the maximum number of parameters
for this version of software. All Parameters are sequential ordered with in the
unit so cycling from ParamId 0 to ParamId = Parameter Count -1 allows for the
host system to learn the Parameter definitions for all Parameters defined for a
given software version. The 16 bit value is packed LSB followed by the MSB.
