CMD12 (3Ch) - Mute Selected Outputs

MRAM = Medium Resolution
Analog Module.

CMD13 (3Dh) - Request Mute Map

A-11
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.
PlnMap0 to access the RGBS Switcher (planes 1, 2, 3 & 4)
Plane # n/a
Plane Use n/a
PlnMap Bit # 7
MuteN 1
Example: Assume an 8 x 8 switch, with RGBS, Composite video and Audio.
3Ch, 87h, A0h, 90h, 97h, 80h, 80h, 80h, 80h, 80h, 80h, 04h
The following outputs are muted:
87h Output 1:
A0h Output 2:
90h Output 3:
97h Output 4:
80h outputs 5 - 8
Response: CMD12, Erc, 80h, 80h, 04h
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.
