Extron electronic 450 Plus Command/response table for SIS commands continued, RGB / Video mute

Command/response table for SIS commands (continued)

Command	ASCII command	Response	Additional
	(host to switcher)	(switcher to host)	description
Digital Sync Validation Processing (DSVP)
Individual sync frequency	X!LS	X1%,X1%]	Listed as horizontal
			frequency, vertical frequency.
Example:	2LS	031.5,060.00]	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.

List input signal status for	0LS	X1^1,X1^2,X1^3, ... ,X1^n]	Each X1^ value is an input.
all inputs			n is the highest-numbered
			input for this model.
RGB / Video mute
RGB/video mute	X#*1B	VmtX#*1]	Mute RGB or video,
			output X# (video off).
RGB/video unmute	X#*0B	VmtX#*0]	Unmute RGB or video,
			output X# (video on).
Read RGB/video mute	X#B	X(]	1 = mute on, 0 = mute off.
Global RGB/video mute	1*B	Vmt1]	Mute all RGB or video
			outputs.
Global RGB/video ummute	0*B	Vmt0]	Unmute all RGB or video
			outputs.
RGB delay
Set RGB delay	EX#*X1#D}	OutX#•DlyX1#]
Example:	E43*7D}	Out43•Dly07]	Set the RGB interval for
			switches to output 43 to 3.5
			seconds (7 x 0.5).
Read RGB delay	EX#D}	X1#]
Example:	E54D}	05]	Output 54 switching interval
			is 2.5 seconds (5 x 0.5).

Audio input gain and attenuation

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

You can set the input level to whole dB values only, using the X!*X%G command. The increment and decrement level (X!+G and X!-G) commands increase and decrease the level in steps of 0.5 dB only. The X$ values for all audio gain and attenuation commands are reported in whole dB levels only; the reported X$ value is rounded up to the next higher magnitude value (for example, 1.5 dB is reported as 2 dB and -3.5 dB is reported as -4 dB).

Set input audio gain to	X!*X%G	InX!•AudX$]
+ dB value
Example:	1*2G	In01•Aud+02]	Set input 1 audio gain to
			+2 dB.
Set input audio attenuation	X!*X^g	InX!•AudX$]
to - dB value
Increment level	X!+G	InX!•AudX$]	Increase audio level by 0.5 dB.
Example:	55+G	In55•Aud+03]	Increment audio input 55
			level from +2 dB to +2.5 dB.
Decrement level	X!-G	InX!•AudX$]	Decrease audio level by 0.5 dB.
Example:	7-G	In07•-09]	Decrement audio input 7
			level from -08 dB to -8.5 dB.
Read input gain	X!G	X$]
