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 at right is for use with
the command/response
table.
Symbol definitions:
= Carriage return/line feed
= Escape key
Esc
= Input number
X1
= Input number (for tie)
X2
= Output number
X3
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.
= Numeric dB value
X4
= Input audio gain
X5
= Input audio attenuation
X6
= Video/audio mute
X7
= Executive mode, mute
X8
= Output gain
X9
= Preset number
X10
See the note about leading zeros in preset numbers on page 4-7.
= Controller firmware version number to second decimal place
X11
= RGB delay in ½ second increments (10 [5 seconds] maximum)
X12

With the exception of the audio input gain and attenuation commands, the SIS
commands are not case sensitive.
= Carriage return (no line feed)
1 through 4 (MVX 44, MVX 48) or 1 through 8 (MVX 84, MVX 88)
0 (untie) – maximum number of inputs
1 through 4 (MVX 44, MVX 84) or 1 through 8 (MVX 48, MVX 88)
–18 to +10 (29 steps [dB] of audio attenuation and gain)
0 through 10 (1 dB/step)
1 through 18 (1 dB/step)
0 = no mutes
1 = video mute
1 = on
0 = consumer level (–10 dBV)
01 through 16
•
= space
2 = audio mute
3 = video and audio mute
0 = off
1 = pro level (+4 dBu)
