SIS™ Programming and Control, cont’d

Command/response table for SIS commands (continued)

Command	ASCII command		Response	Additional
	(host to switcher)		(switcher to host)	description
Digital Sync Validation Processing
List individual sync	X!	LS	X1% X1%]	Listed as H freq., V freq.
frequency			,
Example:	2LS		031.50,060.00]	Input 2 frequency is 31.5
				kHz horizontal and 60 Hz
				vertical.

NThe matrix switcher returns 000.00,000.00 if there is no connection or sync frequencies are not applicable.

Video mute commands

RGB mute	X#*1B	VmtX#*1]
RGB unmute	X#*0B	VmtX#*0]
Read RGB mute	X#B	X(]
Global RGB mute	1*B	Vmt1]
Global RGB unmute	0*B	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.

RGB delay

Set RGB delay	EX#*X1#D}	OutX#•DlyX1#]
Example:	E13*7D}	Out13•Dly07]	Set the RGB interval for
			switches to output 13 to 3.5
			seconds (7 x 0.5 seconds).
Read RGB delay	EX#D}	X1#]
Example:	E14D}	05]	Output 14 interval is 2.5
			seconds
			(5 x 0.5 seconds).

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$]	Increase gain by 1 dB.
Example:	5+G	In05•Aud+03]	Audio input 5 level
			incremented from +2 dB to
			+3 dB.
Decrement gain	X!-G	InX!•AudX$]	Decrease gain by 1 dB.
Example:	7-G	In07•Aud-09]	Audio input 7 level
			decremented from -8 dB to
			-9 dB.
Read input gain	X!G	X$]

Audio output volume

NThe table on page 4-9 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&]
