Software Type: An unsigned 8 bit value indicating the current configuration of t he unit’s

software. The following table shows the values assigned to the available types:

SW Type

THX 1

AC3 2

DTS 3

Software Level: The following table shows the values assigned to the possible software levels:

SW Level

RELEASED 0

PRE_ALPHA 1

ALPHA 2

*Note: SW level indicates the status of the DC-2/MC-1 internal application software.

Software Major Revision: An unsigned 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 integer value indicating this units minor so ft ware version. Indicates

the units software operation has changed but effects, effect parameters, or system

parameters have not changed.

Protocol Major Revision: An unsigned int e ger value indicating the serial communication protocol majo r

version. The host should use this value to determine if new commands,

notifications, or response packets have been added or deleted from this

specification.

Protocol Minor Revision: An unsigned inte ger 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

Total Number of System Parameters: An unsigned integer value indicating the maximum number of

system parameters for this version of software. This should be used to determine

the data count for the “DC-2/MC-1 System Parameter Values Packet” and “Set

System Parameter Values Packet”.

Total Number of Effects: An unsigned integer value indicating the maximum number of effects available

for this version of software. This should be used to determine the maximum

EffectId used in the “Get Effect Definition Packet”, “Get Effect Parameter

Definition Packet”, “Set Effect Name Packet” , and “Set Effect Parameter

Values Packet”.
