CMD12 (3Ch) — Mute Selected Outputs
The Host tells the Matrix to mute specific planes within selected outputs.
Format: CMD12, Mute1, Mute2, ... Mute
n, Cks1, Cks2, EOT
Where: MuteX 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, Cks1, Cks2, 04h
The following outputs are muted:
87h
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, Cks1, Cks2, EOT
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, Cks1, Cks2, EOT
Example: 3Dh, 80h, BDh, 04h
Response: CMD13, Erc, Mute1, Mute2, ... Mute
n, Cks1, Cks2, EOT
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.
CMD14 (3Eh) — Set Sequence
The Host tells the Matrix 200 to create a Sequence of presets and store it under
a specified Sequence number. The command also specifies how long each
preset will run (be active).
Format: CMD14, Seq#, {(PSet#, Hr, Min, Sec, CR), ..} Cks1, Cks2, EOT
Where: SEQ# Sequence number (1 to 31).
(PSET#, Hr, Min, Sec, CR) repeat this string for each Preset that will be
part of the Sequence. Each Preset string will become a sequence “step”.
PSet# Preset number (1 to 20)
Hr
Number of hours to run (0 to 17)
Min
Number of minutes to run (0 to 59)
Sec
Number of seconds to run (0 to 59)
Notes: 1. Maximum number of sequences is 31.
