Command/response table for SIS commands (continued)

Command	ASCII Command	Response	Additional description
	(host to scaler)	(scaler to host)

Audio mute (audio models only)

Mute on	1Z	Amt1]
Mute off	0Z	Amt0]
View status	Z	X8)]

Mute selected input. Un-mute selected input.

View mute status

(0= mute off, 1= mute on).

Audio gain and attenuation (audio models only)

NThe set gain (G) and set attenuation (g) commands are case sensitive. The increment, decrement, and view commands are not. N Add a leading 0 when it is a single digit value

Specific gain	X10@G	Aud X10@ ]	Set gain to X10@ dB.
Set attenuation	X10#g	Aud X10# ]	Set attenuation to X10# dB.
Increment	+G	Aud X10! ]	Increment audio level (up).
Decrement	- G	Aud X10! ]	Decrement audio level (down).
View	G	X10! ]	View current audio level.

Volume control (audio models only)

Specific volume	X10$V
Increment	+V
Decrement	- V
View	V

Test Pattern

NThese commands are not case sensitive.

Vol X10$ ]	Set volume to X10$.
Vol X10$ ]	Increase volume.
Vol X10$ ]	Decrease volume.
X10$ ]	View current volume setting.

Both (J) and (j) can be used interchangeably.

Crop	1J	Tst 1]	Set crop test pattern on.
Alternating pixels	2j	Tst 2]	Set alternate pixels on.
Color bars	3J	Tst 3]	Set color bars on.
Off	0J	Tst 0 ]	Set test pattern off.
View Test Pattern	J	X10$ ]	View the test pattern.

Freeze

NThese commands are not case sensitive. Both (F) and (f) can be used interchangeably

Enable	1f	Frz 1]	Freeze selected input.
Disable	0F	Frz 0]	Unfreeze selected input.
View	F	X8) ]	Show the freeze status (1= on, 0=
			off).
RGB delay time
Set RGB Delay	3*X10& #	Dly X10& ]	Set RGB delay to (X10& x 0.5)
			seconds.
View setting	3#	X10& ]	View RGB delay setting.

N X8) = 0 or 1
X10! = Audio level adjustment	range: -15 to +9 dB
X10@ = Audio gain adjustment	range: 0 to 9 dB
X10# = Audio attenuation	adjustment range: -15 to 0 dB
X10$ = Volume range:	000 to 100 (always returns 3 digits)
X10& = RGB delay:	0 to 10 (0 to 5 seconds in 0.5 second steps)
