CMD23 (47h) — Request the Clock Information
The Host asks the Matrix for its clock settings.
Format: CMD23, Cks1, Cks2, EOT
Example: 47h, 80h, C7h, 04h
Response: CMD23, Erc, Yr, Mo, Day, Hr, Min, Sec, Cks1, Cks2, EOT
Possible Ercs: C4 = Clock not set
CMD24 (48h) — Turn Executive Mode On/Off
The Host requests the Matrix to turn Executive Mode on/off.
Format: CMD24, Mode, Cks1, Cks2, EOT
Where: Mode = 80h turn Executive mode On
81h turn Executive mode Off
Example 1: 48h, 80h, 81h, C8h, 04h
Response: CMD24, Erc, Cks1, Cks2, EOT
Example 2: 48h, 81h, 81h, C9h, 04h
Response: CMD24, Erc, Cks1, Cks2, EOT
CMD25 (49h) — Set RGB Delay
The Matrix is instructed to set values for RGB delay. When switching occurs, the
R, G and B switching will take place after the specified time delay. The sync
switching takes place immediately, but the RGB outputs are muted during this
delay period. This allows the projector to get in sync before the picture arrives,
providing seamless switching.
Format: CMD25, Dly1, Dly2, .... Dly n, Cks1, Cks2, EOT
Where: Bits 0-6 of DlyX represent the RGB-to-sync delay for output X
(expressed in increments of 0.1 sec). The “
n” represents the number of outputs
as determined by command CMD1. (Dly1 = output #1; Dly2 = output #2,
etc.)
Delays must be specified for each output. For zero time delay, DLY =
80h. The time delay depends on the requirements of the output device
(projector, etc.).
Example: 49h, 84h, 90h, etc. says the RGB for output #1 will be delayed by 0.4
seconds, and output #2 will be delayed by 1.6 seconds, etc.
Response: CMD25, Erc, Cks1, Cks2, EOT
CMD26 (4Ah) — Request RGB Delay Information
The Host asks the Matrix to send delay switching information for the RGB
planes.
Format: CMD26, Cks1, Cks2, EOT
Example: 4Ah, 80h, CAh, 04h
Response: CMD26, Erc, Dly1, Dly2, .... Dly n, Cks1, Cks2, EOT
Where: DlyX characters have the same significance as in previous command.
