Command/Response Table for SIS Commands (continued)

Command Function	ASCII Command	Response	Additional description
	(Host to Unit)	(Unit to Host)
RGB mute commands
RGB mute	X@*1B	VmtX@*1]	Mute output X@ RGB (video off).
RGB unmute	X@*0B	VmtX@*0]	Unmute output X@ RGB (video on).
Read RGB mute	X@B	X#]	1 = mute on, 0 = mute off.
Global RGB mute	1*B	Vmt1]	Mute all RGB outputs.
Global RGB unmute	0*B	Vmt0]	Unmute all RGB outputs.

IR 501 mute command responses

NOTE: An IR 501 user can mute video, audio, or both with a string of IR commands that cannot be duplicated by a computer or control system sending SIS commands. The switcher sends the following responses shown in the entries below.

IR 501	RGB and audio mute	{none}	MutX@*1]
			VmtX@*1]
IR 501	RGB mute	{none}
			Zpz]
IR 501	RGB and audio unmute	{none}

The RGB and audio from output X@ are muted.

The RGB from X@ output is muted.

The RGB and audio from output X@ are unmuted.

Audio input gain and attenuation

NOTE: The set gain (G) and set attenuation (g) commands are case sensitive.

Set audio input gain to +dB value Example:

Set audio input attenuation to -dB value

Increment gain

Example:

X$*X%G

1*2G

X$*X&g

X$+G

5+G

InX$•AudX^]
In1•Aud+02]	Set input 1 audio gain to +2 dB.
InX$•AudX^]
InX$•AudX^]	Increase gain by 1 dB.
In5•Aud+03]	Increase audio input 5 level from +2 dB
	to +3 dB.

Decrement gain	X$-G	InX$•AudX^]	Decrease gain by 1 dB.
Example:	7-G	In7•Aud-09]	Decrease audio input 7 level from -8 dB
			to -9 dB.
Read input gain	X$G	X^]
Example:	3G	-06]	Audio input 3 level is at -6 dB.

Audio output level

Set audio output to the consumer level (-10 dBV)

Set audio output to the professional level (+4 dBu)

Read output level

Example:

X@*0*40#

X@*1*40#

X@+40# 3*40#

OutX@•Lvl0]	Set output X@ level to consumer (-10
	dBV).
OutX@•Lvl1]	Set output X@ level to pro (+4 dBu)
	(default).
X*]
1]	Output 3 audio level is pro (+4 dBu).

Audio mute commands

Audio mute	X@*1Z	AmtX@*1]		Mute output X@ audio (audio off).
Audio unmute	X@*0Z	AmtX@*0]		Unmute output X@ audio (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 unmute	0*Z	Amt0]		Unmute all audio outputs.
NOTE: X@ = Output number		1 through 4 (MVX 44, MVX 84) or 1 through 8 (MVX 48, MVX 88)
X# = Mute status		1 = on	0 = off
X$ = Input number		1 through 4 (MVX 44, MVX 48) or 1 through 8 (MVX 84, MVX 88)
X% = Input audio gain		0 through 10 (1 dB per step)
X^ = Numeric dB value		–18 to +10 (29 steps [dB] of audio attenuation and gain)
X& = Input audio attenuation		1 through 18 (1 dB per step)
X* = Output gain		0 = consumer level (–10 dBV)	1 = pro level (+4 dBu)
