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, 80h, 80h, 04h
Example: 33h, 80h, 80h, 04h
Response: CMD3, Erc, 80h, 80h, 04h
The Host asks the Matrix to send the current software version.
The format is "x.y".
Format:CMD4, 80h, 80h, 04h
Example: 34h, 80h, 80h, 04h
Response: CMD4, Erc, SfVer, 80h, 80h, 04h
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
The response is 34h, 80h, 8Dh, 80h, 80h, 04h
