Read ties

NThe & view tie command for RGB and the % view tie command for video can be used interchangeably on the matrix

switcher.
Read video and audio	X@!	X!]
output tie
Read RGB output tie	X@&	X!]
Read video output tie	X@%	X!]
Read audio output tie	X@$	X!]

Video and audio input X! tied to output X@.

RGBHV input X! tied to output X@.

Video input X! tied to output X@.

Audio input X! tied to output X@.

Video mute commmands

RGB or video mute	X@*1B
RGB or video unmute	X@*0B
View RGB or video mute	X@B
Global RGB or video mute	1*B
Global RGB or video unmute	0*B

VmtX@*1] VmtX@*0]

X$]

Vmt1]

Vmt0]

Mute output X@ RGB (video off).

Unmute output X@ RGB (video on).

1 = mute on, 0 = mute off. Mute all RGB outputs. Unmute all RGB outputs.

Audio input gain and attenuation

NThe set gain (G) and attenuation (g) commands are case sensitive. The increment, decrement, and read level commands are not case sensitive.

Set input audio gain to	X%*X^G	InX%•AudX&]
+ dB value
Example:	1*2G	In001•Aud+02]		Set input 1 audio gain to
				+2 dB.
Set input audio attenuation	X%*X*g	InX%•AudX&]
to - dB value
Increment level	X%+G	InX%•AudX&]		Increase audio level by 1 dB.
Example:	5+G	In005•Aud+03]		Increment audio input 5
				level from +2 dB to +3 dB.
Decrement level	X%-G	InX%•AudX&]		Decrease audio level by 1 dB.
Example:	7-G	In007•-09]		Decrement audio input 7
				level from -08 dB to -9 dB.
Read input audio level	X%G	X&]
Audio mute
Audio mute	X@*1Z	AmtX@*1]		Mute audio output X@
				(audio off).
Audio unmute	X@*0Z	AmtX@*0]		Unmute audio output X@
				(audio on).
Read audio mute	X@Z	X$]		1 = mute on, 0 = mute off.
Global audio mute	1*Z	Amt1]		Mute all audio outputs.
Global audio ummute	0*Z	Amt0]		Unmute all audio outputs.
N X@ = Output number		001 – maximum number of outputs
X! = Input number		000 – maximum number of inputs (000 = untied)
X$ = Mute status		0 = off (unmuted)	1 = on (muted)
X% = Input number		001 – maximum number of outputs
X^ = Audio gain		00 – 09 (1 dB per step)
X& = Numeric dB value		-24 – +09
X* = Audio attenuation		-01 – -24 (1 dB per step)
