Switcher error responses

When the switcher receives an SIS command and determines that it is valid, it performs the command and sends a response to the host device. If the switcher is unable to perform the command because the command is invalid or contains invalid parameters, the switcher returns an error response to the host. The error response codes are:

E01 — Invalid input channel number (out of range)

E10 — Invalid command

E11 — Invalid preset number (out of range)

E12 — Invalid output number (out of range)

E13 — Invalid value (out of range)

E14 — Invalid command for this configuration

Using the command/response table

The command/response table begins on page 4-5. Symbols used in the table represent variables in the command/response fields. Command and response examples are shown throughout the table. The ASCII to HEX conversion table below is for use with the command/response table.

ASCII to HEX Conversion Table

Space

NWith the exception of the audio input gain and attenuation commands, the SIS commands are not case sensitive.

Symbol definitions:

] = Carriage return/line feed

}= Carriage return (no line feed)

• = space

E = Escape key

X!	= Input number (for tie)	0 (untie) – maximum number of inputs
X@	= Output number	1 through 4 (MVX 44, MVX 84) or 1 through 8 (MVX 48, MVX 88)

N Input and output numbers in commands may be entered as either 1-digit, 2-digit, or 3-digit numbers. All input and output numbers are

	reported as 1-digit numbers in the response.
X#	= Executive mode, mute	1	= on 0 = off
X$	= Input number	1 through 4 (MVX 44, MVX 48) or 1 through 8 (MVX 84, MVX 88)
X%	= Input audio gain	0 through 10 (1 dB/step)
X^	= Numeric dB value	–18 to +10 (29 steps [dB] of audio attenuation and gain)
X&	= Input audio attenuation	1 through 18 (1 dB/step)
X*	= Output gain	0	= consumer level (–10 dBV) 1 = pro level (+4 dBu)
X(	= Preset number	00 through 16 (00 = current configuration)
X1)	= Video/audio mute	0	= no mutes	2 = audio mute
		1	= video mute	3 = video and audio mute
X1!	= RGB delay in ½ second increments (10 [5 seconds] maximum)
X1@	= Controller firmware version number to second decimal place
