CMD3 (33h) — Turn Power Off
The Host tells the Matrix to turn power off. The action is independent of other
active control ports, e.g., Front Panel Controller.
Format: CMD3, Cks1, Cks2, EOT
Example: 33h, 80h, B3h, 04h
Response: CMD3, Erc, Cks1, Cks2, EOT
CMD4 (34h) — Send Software Version
The Host asks the Matrix to send the current software version. The format is
“x.y”.
Format: CMD4, Cks1, Cks2, EOT
Example: 34h, 80h, B4h, 04h
Response: CMD4, Erc, SfVer, Cks1, Cks2, EOT
Example: Assuming software version is 1.3 (x=1, y=3)
To determine the SfVer from x.y:
1. calculate 10x + y (decimal) (10x1 + 3 = 13d)
2. convert to hex (13d = Dh)
3. force bit 7 to become 8Dh
Response: 34h, 80h, 8Dh, Cks1, Cks2, 04h
