Command/response table for SIS commands (continued)

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

Audio input gain and attenuation

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

Set input audio gain to +dB	X!*X%G	InX!•AudX$]
value
Example:	1*2G	In01•Aud+02]	Set input 1 audio gain to
			+2 dB.
Set input audio attenuation	X!*X%g	InX!•AudX$]
to -dB value
Increment gain	X!+G	InX!•AudX$]	Increase gain by 1 dB.
Example:	5+G	In05•Aud+03]	Increase Audio input 5 level
			from +2 dB to +3 dB.
Decrement gain	X!-G	InX!•AudX$]	Decrease gain by 1 dB.
Example:	7-G	In07•Aud-09]	Decrease audio input 7 level
			from -8 dB to -9 dB.
Read input gain	X!G	X$]

Audio output volume

NThe table on page 4-8 defines the value of each audio volume step.

Set the audio volume to a	X#*X&V	OutX#•VolX&]
specific value
Example:	1*50v	Out01•Vol50]	Set output 1 volume to 79%.
Increment volume	X#+V	OutX#•VolX&]	Increment volume by 1 step.
Example:	1+V	Out01•Vol51]
Decrement volume	X#-V	OutX#•VolX&]	Decrease volume by 1 step.
Read output volume	X#V	X&]
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.
