Extron electronic MTPX Plus Series X1$ =, X3# =, X3@ =, which can consist of from 1 to 16 outputs

X1$ =		Local output sync polarity	0	= H- / V- (default)
			1	= H+ / V-
			2	= H- / V+
			3	= H+ / V+
			4	= No sync stripping (composite, S-video, YUV)
X1%	=	Local audio output number	1	– 4 (matrix sizes 1616 and smaller)
			1	– 8 (matrix sizes 1632 and larger)
X1^ =		Volume adjustment range	0	– 64 (1 dB/step except for 0-to-1, which is 22 dB)
			(default = 64 [0 dB])
			(See the table on page 4-14.)
X1& =		Audio gain	0	– 24 (1 dB/step)
X1*	=	Numeric dB value	–18 to +24 (45 steps of gain or attenuation) (Default = 0 dB)
X1( =		Audio attenuation	1	– 18 (1 dB/step)
X2)	=	Global or room preset #	0	- 32, 10 maximum for a room preset (0 = current configuration)

N A Room preset is a stored configuration with all of the outputs assigned to a single room. When a room preset is retrieved from memory, it becomes the current configuration.

X2! = Name	12 characters maximum for input, output, and global preset names
	Upper- and lower-case alphanumeric characters and
	_ / and spaces are valid.

NThe following characters are invalid in the name: {space} ~ , @ = ‘ [ ] { } < > ’ “ ; : \ and ?.

X2@ = Room # (for room presets) 10 max. (each can have up to 10 presets (X2)s) assigned)

N A Room is a subset of operator-selected outputs that relate to each other. The MTPX Plus switchers support up to 10 rooms, each of

which can consist of from 1 to 16 outputs.

X2# = Group # (for I/O grouping)

X2$ = Audio or RS-232 mute:

1 through 4 groups (0 = no group)

0 = no mutes

2 = audio or RS-232 mute

X2%	=	Local input select DIP switch status	0 = RJ-45 position, 1 = local input position
X2^ =		Number of inputs	8, 16, or 32
X2& =		Number of outputs	8, 16, or 32
X2*	=	Part number	60-nnn-nn
X2( =		Firmware version number to second decimal place (x.xx)
X3)	=	Verbose firmware version-description-upload date/time.
		See the Query firmware version (verbose) command on page 4-22.
X3! =		Voltage	Positive or negative voltage and magnitude
X3@ =		Internal temperature	Degrees Fahrenheit
X3# =		Fan speed	RPM
