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.
With 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
Esc
= Escape key
X1
= Input number 1 through 4 (MVX 44, MVX 48) or 1 through 8 (MVX 84, MVX 88)
X2
= Input number (for tie) 0 (untie) – maximum number of inputs
X3
= Output number 1 through 4 (MVX 44, MVX 84) or 1 through 8 (MVX 48, MVX 88)
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.
X4
= Numeric dB value –18 to +10 (29 steps [dB] of audio attenuation and gain)
X5
= Input audio gain 0 through 10 (1 dB/step)
X6
= Input audio attenuation 1 through 18 (1 dB/step)
X7
= Video/audio mute 0 = no mutes 2 = audio mute
1 = video mute 3 = video and audio mute
X8
= Executive mode, mute 1 = on 0 = off
X9
= Output gain 0 = consumer level (–10 dBV) 1 = pro level (+4 dBu)
X10
= Preset number 01 through 16
See the note about leading zeros in preset numbers on page 4-7.
X11
= Controller firmware version number to second decimal place
X12
= RGB delay in ½ second increments (10 [5 seconds] maximum)
