CMD25 (49h) - Set RGB Delay

CMD26 (4Ah) - Request RGB Delay Information

Extron • Matrix 100 • User's Manual
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, .... DlyN, 80h, 80h, 04h
Where: Bits 0-6 of each "Dly" byte represent the RGB-to-sync delay for that
output (expressed in increments of 0.1 sec). "N" represents the number of last
available output, 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 (84h) will be delayed
by 0.4 seconds, and output #2 (90h) will be delayed by 1.6 seconds, etc.
Response: CMD25, Erc, 80h, 80h, 04h
The Host asks the Matrix to send delay switching information for each of the
RGB planes.
Format:CMD26, 80h, 80h, 04h
Example: 4Ah, 80h, 80h, 04h
Response: CMD26, Erc, Dly1, Dly2, .... DlyN, 80h, 80h, 04h
Where: The "Dly" characters have the same significance as in previous
command (CMD25). "N" represents the number of last available output, as
determined by command CMD1. (Dly1 = output #1; Dly2 = output #2, etc.)
