CMD8 (38h) - Download Status and Presets
The Host asks the Matrix 100 to send the contents of the specified preset.
Same variables are used as in CMD7. Stored presets are numbered 1 thru 8.
_______ The current Matrix setup can be accessed as preset # 0.
Format: CMD8, Preset, 80h, 80h, EOT
Response: CMD8, Erc, {(BdAd, Inp1, Inp2, ...Inpn, CR), ...}, 80h,
80h, 04h
Possible Ercs: C1 = Preset file not found
Where: Preset can be 80h (current configuration) or 81h (1) thru 88h (8).
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, 80h, 80h, 04h
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 = 080h, 083h. Red and Green channels are
muted. All RGB displays connected to Matrix 100 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, 80h, 80h, 04h
Where: Preset can be 81h (1) thru 88h (8).
Response: CMD10, Erc, 80h, 80h, 04h
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, 80h, 80h, 04h
Response: CMD11, Erc, 80h, 80h, 04h
Possible Ercs: C2 = Preset file not found
