Set audio gain and attenuation

NOTE: The set gain (G) and set attenuation command (g) are case sensitive. The increment, decrement and view commands are not case sensitive.

Set gain	X!*X2#G	X!AudX2@]
Example:	4*3G	4Aud+•3]
Set attenuation	X!*X2$g	X!AudX2@]
Increment level	X!+G	X!AudX2@]
Decrement level	X!–G	X!AudX2@]
View audio level	X!g	X2@]
Example:	4G	–•3]

Set gain for input X! to X2# dB. Set gain for input 4 to 3 dB.

Set attenuation for input X! to –X2@ dB. Increase input X! audio level by +1 dB. Decrease input X! audio level by –1 dB. View gain for input X!.

The ISM reports that the input 4 audio level is at –3 dB of attenuation.

Audio mute

	Audio mute on	X@*1Z	X@AmtX#]	Mute the X@ audio output.
	Audio mute off	X@*0Z	X@AmtX#]	Unmute the X@ audio output.
	View audio mute status	X@Z	X#]	Audio mute is X# for X@ output.
Front panel security lockout (Executive mode)
	Disable	0X	Exe0]	Adjustments and selections can
				be made from the front panel.
	Enable (lock image adjustments)	1X	Exe1]	Lock front panel adjustments;
				adjust image via RS-232 only.
	View the executive mode status	X	X#]	Show executive mode status.
	Example:	X	0]	Executive mode is off.
Verbose mode
	NOTE: The default for verbose mode is on for the RS-232 connection and off for Ethernet connections.
	Disable (block reports)	E0CV}	Vrb0]	Turn off verbose mode. The ISM does
				not send the reports listed in Switcher-
				initiated messages earlier in this
				chapter.

NOTE: Disabling verbose mode blocks reports for front panel operations only, to this connection (RS-232 or Ethernet) only. The ISM continues to send responses to SIS commands to all ports. The ISM continues to send reports for front panel operations to other connections.

Enable (allow reports)	E1CV}	Vrb1]	Turn on verbose mode. The ISM sends
			all reports.
View the verbose mode status	ECV}	X#]	Show verbose mode status.
Example:	ECV}	1]	Verbose mode is on (the ISM ISMues
			reports).
NOTE: X! = Input number		1 through 8
X@ = Output number		1 or 2
X# = Freeze and front panel lock status		0 = off, 1 = on
X2# = Gain/attenuation		-24dBto +•9dB, each step = 1 dB
X2$ = Gain value		Numeric dB value, 0 to +9
X2% = Attenuation value		Numeric dB value, –1to –24
