Command/response table for SIS commands (continued)

Command	ASCII command	Response	Additional
	(host to switcher)	(switcher to host)	description
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.

NAn IR 501 user can mute video and/or audio 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:

IR 501 RGB and audio mute	{none}	MutX@*1]	Output X@’s RGB and audio
			are muted.
IR 501 RGB mute	{none}	VmtX@*1]	Output X@’s RGB is muted.
IR 501 RGB and audio	{none}	Zpz]	Output X@’s RGB and audio
unmute			are unmuted.

Audio input gain and attenuation

NThe set gain (G) and set attenuation (g) commands are case sensitive.

Set audio input gain to +dB	X$*X%G	InX$•AudX^]
value
Example:	1*2G	In1•Aud+02]	Set input 1 audio gain to +2 dB.
Set audio input attenuation	X$*X&g	InX$•AudX^]
to -dB value
Increment gain	X$+G	InX$•AudX^]	Increase gain by 1 dB.
Example:	5+G	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	X@*0*40#
consumer level (-10 dBV)
Set audio output to the	X@*1*40#
proffesional level (+4 dBu)
Read output level	X@+40#
Example:	3*40#

OutX@•Lvl0]

X*]

1]

Set output X@ level to consumer (-10 dBV).

Set output X@ level to pro (+4 dBu) (default).

Output 3 audio level is pro (+4 dBu).

N X@= Output number	1	– (maximum number of outputs for your model)
X#= Mute	1	= on (muted)
X$= Input number	0	= off (unmuted)
	1	– (maximum number of inputs for your model)
X%= Audio gain	0	– 24 (1 dB/step)
X^= Numeric dB value	–18 to +24 (45 steps of gain or attenuation) (Default = 0 dB)
X&= Audio attenuation	1	– 18 (1 dB/step)
X*= Output gain	0	= consumer level (–10 dBV)
	1	= professional level (+4 dBu)
