Notes:

4.This command is only available in System 4xi units with the following firmware revision levels, or higher:

System 4LDxi – revision 3.0 System 4LQxi – revision 4.0

6.Only available on System 4LDxi and 4LQxi.

Aud Lvl	C1h - FFh = Audio level (-31dB to +31dB)
H Shift	81h	- FFh = Horizontal shift (-63 to +63 in steps of 2)
Cont	81h	- FFh = Contrast level (-63 to +63 in steps of 2)
Color	81h	- FFh = Color level (-63 to +63 in steps of 2)
Tint	81h	- FFh = Tint level (-63 to +63 in steps of 2)
Chroma Det	81h	= On
	82h	= Off
	83h = not supported
Luma Det6	81h-84h = Decoded-modes Sharpness levels 1 - 4
	80h = not supported
reserved	80h	= reserved
EOT	04h	= End Of Transmission

Example:

Request Configuration for Input Channel #4: 1Bh, 3Ah, 84h, 04h

Response example:

Input #4 is configured for line-doubled S-video (motion), Audio at 0dB and all picture controls (H Shift, Contrast, Color and Tint) at mid-range (zero), Chroma Detail (not applicable), Luma Detail at level 1.

This would be:

1Bh, 3Ah, 80h, 8Ah, E0h, C0h, C0h, C0h, C0h, 82h, 81h, 80h 04h
