CMD8 (38h) — Download Status and Presets
The Host asks the Matrix 200 to send the contents of the specified preset. Same
variables are used as in CMD7. (Stored presets are numbered 1 thru 20,
however, the current Matrix setup can be accessed as preset “0”.)
Format: CMD8, Preset, Cks1, Cks2, EOT
Response: CMD8, Erc, {(BdAd, Inp1, Inp2, ...Inp
n, CR), ...}, Cks1,
Cks2, EOT
Possible Ercs: C1 = Preset file not found
Where: Preset can be 80h (current configuration) or 81h (1) thru 94h (20).
As described in CMD7, there is a data string for each plane starting with
its board address (BdAd) and ending with 0Dh (carriage return).
CMD9 (39h) — Mute All Planes
The Host instructs the Matrix to mute (deactivate) all outputs in specified planes.
Format: CMD9, PlnMap1, PlnMap0, Cks1, Cks2, EOT
Where: PlnMap1 and PlnMap0 follow the format described for CMD1.
Bits are “0” for normal operation and “1” to mute the plane.
Example: If PlnMap1, PlnMap0 = 80h, 83h. Red and Green channels are
muted. All RGB displays connected to Matrix 200 outputs will show
only the blue component of the signal.
_______ At this time, only PlnMap0 is supported by hardware. PlnMap1 = 80h.
Bits for nonexisting planes are forced to 0.
CMD10 (3Ah) — Save Current as Preset #
The Host tells the unit to save its current connections as a preset.
(The preset can be called later using CMD11.)
Format: CMD10, Preset, Cks1, Cks2, EOT
Where: Preset can be 81h (1) thru 94h (20).
Response: CMD10, Erc, Cks1, Cks2, EOT
Possible Ercs: C3 = Out of memory space
CMD11 (3Bh) — Load Preset #
The Host tells the Matrix to load (activate) a stored preset configuration. The
connections previously stored under the specified preset number become active.
The current connections are lost, unless they have also been saved as a preset.
Format: CMD11, Preset, Cks1, Cks2, EOT
Response: CMD11, Erc, Cks1, Cks2, EOT
Possible Ercs: C2 = Preset file not found
