CMD12 (3Ch) - Mute Selected Outputs
The Host tells the Matrix to mute specific planes, within selected outputs.
Format: CMD12, Mute1, Mute2, ... MuteN, 80h, 80h, 04h
Where: MuteN specifies planes to be muted for the output corresponding to the
mute byte number. This uses the same format as PlnMap shown below.

3Ch, 87h, A0h, 90h, 97h, 80h, 80h, 80h, 80h, 80h, 80h, 04h
The following outputs are muted:

Output 1:
R, G, B (leave sync on)
A0h
Output 2:
Audio Stereo (Left + Right)
90h
Output 3:
Composite video
97h
Output 4:
R, G, B and Composite video
80h
outputs 5 - 8
Outputs not muted
Response: CMD12, Erc, 80h, 80h, 04h
CMD13 (3Dh) - Request Mute Map
The Host asks the Matrix to send which outputs are muted. The response sends
back the same data, in the same format as CMD12.
Format: CMD13, 80h, 80h, 04h
Example: 3Dh, 80h, 80h, 04h
Response: CMD13, Erc, Mute1, Mute2, ... MuteN, 80h, 80h, 04h
Where: MuteX specifies planes to be muted for the output corresponding to the
mute byte number. This uses the same format as PlnMap shown above.
